== Use Cases ==
 +
To focus the discussion, please add use cases below that will help show what problems the citation microformat will be solving.

== Contributors ==
+
Use cases for both publishing and consuming citation information can help to focus citation brainstorming on efforts that provide real world utility to users.
 +
For now, please add any uses cases you think of, however common or obscure (feel free to note opinions as to expected/known frequency of use of such use cases).
 +
 +
=== improve web citations ===
 +
Articles on the web often cite other online articles with permalinks (e.g. <span id="Blogs_quoting_other_resources.2C_including_blogs">blogs quoting other resources, including blogs</span>). Such web citations could be improved both in content and interaction in a number of useful ways:
 +
* '''richer citations.''' Existing web citations typically include only permalink URL and article title in a hyperlink. An explicit format (both in microformat and style) for web citations could encourage the use of richer citations with information like author and date(time) of publication. Author information is useful because it provides an immediate inline proxy for reputation, and date of publication is useful because it sets a context for the information backed by the citation.
 +
* '''richer citation interfaces.''' Web articles sometimes provide an explicit user interface to copy/paste a permalink for reference purposes, or a hyperlink embed code for linking to the article from another web article. An explicit markup structure/format could encourage such interfaces to provide a richer citation structure (e.g. including author, date of publication) to copy/paste, with little to no change in overall UI. This is useful in that it would help propagate richer citations themselves, which have the advantages mentioned above.
 +
 +
Additional useful rich citation enhancements:
 +
* '''access date.''' Rich citations could include the access date when an author (blogger) made a citation, because resources on the other side of those links can change without notice.

== Use Cases ==
+
=== I read this ===
 +
A reader wants to collect a set of things they've read (e.g. on the web), perhaps for the purposes of cataloging them, adding notes, and using the information to generate later citations, potentially in other forms, such as BibTeX or Docbook, for inclusion in a publication of their own.
-
To focus the discussion, please add use cases below that will help show what problems the citation microformat will be solving.
+
If web articles (e.g. blog posts) contained discoverable descriptions of self-citations (e.g. permalinks plus authorship), browsers/aggregators could both automatically collect these, perhaps as part of an enhanced browser history functionality, or allow explicit collection, e.g. bookmarking with additional structure.
-
I've included two, focusing on consuming information - I've assumed that use cases for generating microformatted content would just involve the desire to enable your content to be consumed better, but I'm interested to see if there's something I'm missing here -Mike
+
Notes: In this case, it isn't important to the user what style the citation takes as displayed on the page where they find it. What *is* important is that it contains enough information to allow generation of the format they will ultimately re-publish it in. This implies that it may be worthwhile to err a little on the side of verbosity, but at most enough to provide typical TCMOS/APA/MLA citations.
-
=== Acquiring reference information from the web ===
+
=== collect further reading ===
 +
Was part of <span id="Acquiring_reference_information_from_the_web">Acquiring reference information from the web</span>.
-
A user either finds an author's papers page, or is viewing the results of a search and would like to import the information about the displayed papers into their local reference database, for the purposes of cataloging things they've read, adding notes, and using the information to generate later citations, potentially in other forms, such as BibTeX or Docbook, for inclusion in a publication of their own.
+
A reader finds a list of citations (e.g. a paper's bibliography, an author's papers page, results of a search for academic papers), and wants to add them to a queue of things they'd like to read, perhaps as part of further research on whatever subject/person they were reading/researching.

Marking up the list of citations with a microformat would enable to browsers/aggregators to present an explicit list of structured citations with a user interface for one-click addition to a read it later list (or a local reference database).
-
Also, links to downloadable full representations of the cited work are very important - e.g. a link to the PDF of a journal article, or to a music file.

Links to downloadable full representations of the cited work (e.g. link to the PDF of a journal article, or to a music file) would help the reader find cited works, and perhaps even have their browser/aggregator prefetch/cache/download them.

=== Blogs quoting other resources, including blogs ===
 
-
Any blog that cites online content, whether a blog or news article, could use an hCitation to properly link to the cited reference. Such citations could include the access date when the blogger made the citation, because resources on the other side of those links can change without notice.
 
-
 
-
Instead, today we have simple formating with a link to the permaURL. The citation data is completely lacking. See [http://doc.weblogs.com Doc Searl's blog] for a style of referencing that could benefit from proper a citation uF.
 
-
 
-
 
-
Fascinating... after I added the last two use cases, I realized they focus on potentially marginal cases. The first because it is missing the "output" part of the cut & paste, where the uF would actually be used as part of the paste.  The latter because bloggers have a working citation mechanism that is just a link to the URL (hopefully a permaURL). One could argue they wouldn't want a full hCitation. And in fact, until a tool exists that makes it easy, they probably won't.  However, a tool that cuts & pastes from anywhere on the web into a blog with a full citation seems like a nice tool.  But again, I'm not really paving the cowpaths with these ideas. -Joe Andrieu

Adding a class of, say, "self" to an attribute of the proposed strawman would allow users (or user agents) to extract the data required to cite the page being visited, when referring to it elsewhere. There would be the added advantage of allowing the citation to be ignored by any parser which might be building a "tree" of citations, and preventing the setting up of an infinite loop.

A user agent should be capable of reading a citation from a web page, in a given format, and converting it into a second format, for use elsewhere. For a list of such formats, and examples, see [http://en.wikipedia.org/wiki/Citation#Format_styles  Wikipedia, Citation styles]. [[User:AndyMabbett|Andy Mabbett]] 11:05, 30 Mar 2007 (PDT)

==Requirements==
+
-
 
+
-
Generally, use cases are used to flesh out requirements, but I don't see any on this page, so I've added a new section for this.  Here are some suggested requirements. [[ThomasBreuel]]
+
-
 
+
-
===Possible Requirement: Lossless Round-Trip Conversions===
+
-
 
+
-
One of the primary uses for a citation format is to permit people to put individual citations or entire bibliographies on the web.  For that purpose, it's important that if someone puts up my bibliography on the web and someone else downloads it, they actually get back the citations correctly, and don't have to spend time fixing up the citations manually.  Therefore, I suggest the following requirement.
+
-
 
+
-
''If X is one of the common citation formats (BibTeX, EndNote, etc.), then conversion of the form X -> hCitation -> X must not lose information and must not require manual fixing up of the result.''
+
-
 
+
-
Note that this has multiple components.  First, for a format like BibTeX, it's important that the field names be preserved.  Second, in general, markup (italics, math, chemical formulas, spacing, special characters) needs to be preserved.
+
-
 
+
-
===Possible Requirement: Citation Markup===
+
-
 
+
-
Citations may contain markup, such as italics, subscripts, superscripts, special characters, and chemical formulas.  For a correct presentation of the citation format to the user, the format must permit even fairly complex markup.  Note that this markup cannot easily be converted automatically between different bibliographic processors.
+
-
 
+
-
===Possible Requirement: Encapsulation of Non-Semantic Content===
+
-
 
+
-
===Possible Requirement: No Additional Converters===
+
-
 
+

== Original hBib Discussion ==
+
== principles ==
 +
Principles help guide and compare various different brainstorming proposals.
-
During the WWW2005 Developer's Day [[microformats]] track, Rohit Khare gave a [[presentations|presentation]] where he discussed the microformats [[process]], and then did  a quick demonstration wherein a bunch of us got on a shared Subethaedit document, and brainstormed some thoughts on what an "hBib" bibliography citation microformat would look like.  Rohit placed the [http://cnlabs.commerce.net/~rohit/hBib%20Discussion.html document on his Commercenet site].
+
In the first three years of development the citation microformat effort generated a number of brainstorm proposals without clear consensus or adoption of any of them in particular. Thus any new (2012+) proposals must be written with references to particular principles for each design decision, justifying why/how the new proposal is an improvement upon previous proposals.
-
* http://cnlabs.commerce.net/~rohit/hBib%20Discussion.html
+
Principles to use:
 +
* microformats design [[principles]]
 +
* Semantic HTML Design Principles
 +
* use as precise as HTML semantics as are available
-
''An attempt to summarize and inline the linked document follows. -Mike''
+
=== Semantic HTML Design Principles ===
 +
{{semantic-html-design-principles}}
-
Two major goals were outlined by the group:
+
Brainstorm proposals should take into account the Semantic HTML Design Principles.
-
* Avoid re-keying references
+
=== semantic elements to consider ===
-
* Adapt to new journal styles by changing CSS
+
One of the guiding principles of Microformats is to encourage the use of the most precisely semantically rich element to describe each node (Point 2 of Semantic HTML Design Principles: Use the most accurately precise semantic HTML building block for each object etc). Since we are dealing with HTML and citations, several elements are candidates to be used to enrich the semantic meaning. [http://www.w3.org/TR/REC-html40/struct/text.html CITE, BLOCKQUOTE, Q, A], (are there more?)
-
+
-
The fundamental problem was discussed in terms of display - the ability to transform XHTML+hBib into the many journal-specific formats. For example, how to display "et.al" when all authors are present in the source, and how to re-order the elements if a style defines a set order of elements that conflicts with the ordering in the source. Using hCard for authors was agreed on, and the beginnings of an example were shown.
+
-
== XHTML Structure ==
+
== brainstorm proposals ==
-
With my exprience working X2V and hCa* has taught me what elememts are easy to find and which are not. Since the Citation microformat is very new it is possible to not make a lot of the same errors twice and to make things easier for extracting application to find and imply certain properties.
+
-
* There should be some sort of 'root node' that implies all child elements are for the hCitation microformat.
+
=== web citations ===
-
* Since most people will have multiple citations there should be away to represent each hCitation object as a unqiue block independent of another. This is to keep the parse from finding 'author' and applying that to all citations. Each citation should be in a container (class="hcite") that is separated from others.
+
{{main|h-cite}}
-
* Perhaps class="hcite" with <code>&lt;cite&gt;</code> recommended as the root element. E.g. <code>&lt;cite class="hcite"&gt;</code>
+
-
'''Note: This section was the original content of the document. Since then, class='hcite' has been agreed on as the root class name. See  [http://microformats.org/wiki?title=citation-brainstorming#.27hcite.27_as_Root_Element_name explanation].'''
+
This brainstorm has now been moved to a draft microformat:
 +
* [[h-cite]]
-
== Citation vs. [[media-info]] ==
+
The remainder of this brainstorm proposal is left here for historical purposes:
-
What distinguishes a cite from say [[media-info]] (e.g. [[media-info-examples]]) is that a cite is a reference to something explicitly external to the current piece of content or document, whereas [[media-info]] describes information about content embedded or inline in the current document.
+
The <dfn>web citations</dfn> proposal uses a smaller, [[simpler]] set of only ''eight'' properties to solve the [[specific]] problem of how to markup citations in an article <em>on the web</em> that refers to other articles <em>on the web</em>. Offline to offline, and online to offline references are specifically not addressed.
-
== Semantic Meaning ==
+
==== web citations background ====
-
One of the guiding priniciple of Microformats is to use the most semantically rich element to describe each node (Point 2 of Semantic XHTML Design Principles: Use the most accurately precise semantic XHTML building block for each object etc). Since we are dealing with HTML and citations, several elements are candidates to be used to enrich the semantic meaning. [http://www.w3.org/TR/REC-html40/struct/text.html CITE, BLOCKQUOTE, Q, A], (are there more?)
+
This work is based on how existing [[citation-formats#styles|citation format ''styles'']] (APA, MLA, TCMOS) represent references to articles on the web, and is designed to match the implied schema of those styles. The web citations proposal defines how to markup such reference representation styles in order to satisfy the use-cases above.
-
The [[citation-brainstorming|Citation Brainstorming Page]] has a few development and ideas about how to give another person credit for a link. Some of the semantic ideas behind their choices of tags can be applied to a full bibliographic type reference. ''Does this sentence make sense only historically? -Mike''
+
==== web citation illustrative example ====
 +
Here is a simple minimal abstract web citation example:
 +
<source lang=html4strict>
 +
<span class="h-cite">
 +
  <time class="dt-published">YYYY-MM-DD</time>
 +
  <span class="p-author h-card">AUTHOR</span>:
 +
  <cite><a class="u-url p-name" href="URL">TITLE</a></cite>
 +
</span>
 +
</source>
-
== OCLC's WorldCat for titles ==  
+
==== web citation properties ====
-
Question: what about using something like OCLC's [http://www.oclc.org/worldcat/open/isbnissnlinking/default.htm WorldCat] for linking titles? - Tim White
+
root classname: '''<code>h-cite</code>'''
-
== This and That ==
+
In rough order of presentation and relevance/frequency:
-
After reading through alot of different citation encoding formats, i noticed that each format was being used in onw of two ways. It was either to describe the Current page (THIS.PAGE) or being used to encode references that point to external resources (THAT.PAGE)
+
-
The informatation being encoded was identical for both resources (author, date, name, etc) they just reference different things. For this microformat, i'm not sure if we want to try to solve both problems, or just one? The meta tags in the head element would be the ideal place for information about the THIS.PAGE, but that is not in following with the ideals of microformats where information is human-readable. The THAT.PAGE idea where a list of references is at the end of a document in the form of a bibliography is more inline with the ideals of a microformat where the data is human-readable. That doesn't mean that data about the current document shouldn't be human-readable, so some of the same properties used to reference extermal resources can be used for the current document (THIS.PAGE). To do this a different root item could be used and transforming applications could either extract the citation data about the current page, or information about this page's references.
+
properties:
 +
* '''<code>dt-published</code>''' - reused from [[uf2]] h-entry
 +
* '''<code>p-author</code>''' - same, with optional substructured h-card
 +
* '''<code>p-name</code>''' - common property instead of entry-title
 +
* '''<code>u-url</code>''' - a URL to access the cited work
 +
* '''<code>u-uid</code>''' - a URL/URI that uniquely/canonically identifies the cited work, canonical permalink.
 +
* '''<code>p-publication</code>''' - for citing articles in publications with more than one author, or perhaps when the author has a specific publication vehicle for the cited work. Also works when the publication is known, but the authorship information is either unknown, ambiguous, unclear, or collaboratively complex enough to be unable to list explicit author(s), e.g. like with many wiki pages.
 +
* '''<code>dt-accessed</code>''' - date the cited work was accessed for whatever reason it is being cited. Useful in case online work changes and it's possible to access the dt-accessed datetimestamped version in particular, e.g. via the Internet Archive.
 +
* '''<code>p-content</code>''' for when the citation includes the content itself, like when citing short text notes (e.g. tweets).
-
This is open for discussion, but either way, i believe that the properties used to describe a page will be the same for both THIS and THAT. [http://suda.co.uk/ brian suda]
+
==== web citations vs previous proposals ====
 +
I think the biggest problem with all previous proposals is that they tried to do too much. They didn't design a citation ''micro''format that could be used as a building block, but rather, erred on the side of attempting to describe the myriad types of references to dead-tree resources. They were so over-designed that their authors didn't even dogfood them on their own sites. -- [[User:Tantek|Tantek]] 00:56, 7 August 2012 (UTC)
-
== More on This and That ==
+
A primary goal of the web citation effort is to both start small, and always "make small possible", that is, no matter how it is extended, continue permitting very small meaningful citations with perhaps only 2-3 properties (e.g. date published, author, name of work).
-
Citation microformats are being explored as a possibility for citing genealogical information at [http://eatslikeahuman.blogspot.com Dan Lawyer's blog].
+
==== web citations design principles ====
 +
Principles driving this proposal:
 +
* '''solve a [[specific]] problem'''. In this case '''web citations''' seeks to solve a ''more'' specific problem than previous proposals, that of citations from the web to the web (more constrained than any publication to any publication).
 +
* [[solve simpler problems first]]. Existing web-to-web citations contain very little information compared to generalized academic citations, thus '''web citations''' is greatly simplified compared to previous proposals by only starting with a handful of properties.
 +
* [[humans first]] - '''web citations''' focuses on the human readability and writability aspects of citations in articles first and foremost, and only secondarily considers the machine readability/reusability of the data contained therein.
 +
* [[reuse]] building blocks - by re-using the better designed aspects of [[citation-formats#styles|existing citation conventions]] for web resources, '''web citations''' builds on top of previous work to make citations human readable/writable, as well as what implied properties are commonly expressed by such previous work.
-
This is a case where frequently the citation would refer to (THIS.PAGE), but would have nested within it a reference to (THAT.PAGE), possibly a few levels deep. For instance, a web page might contain data extracted from a microfilm of a census. The citation would need to include information about the web page, information about the microfilm, and information about the census. Genealogical citations are expected to include the repository (where can this book or microfilm be found. Is this the same as ''venue''?). So, at each level the information should contain the repository of the referenced item. A nesting (recursive) mechanism for citation microformats would be useful in this case. Is this the function of the "container" element in the Straw Format?
+
==== web citation property details ====
 +
(stub)
-
== Date Formatting ==
+
All web citation properties are derived from the implied schema in [[citation-formats#styles|existing citation styling guides]] for citing permalinks to articles and short text notes online.
-
Since microformats are all about re-use and the accepted way to encode Date-Time has been pretty much settled, then this is a good place to start when dealing with all the different date citation types.  
+
-
These are all the different fields from various citation formats that are of temporal nature:
+
Date-time properties (dt-published, dt-accessed) may optionally include time information in addition to the date if relevant to the citation (e.g. when citing short text notes (tweets) of which there may be several in a single day).
-
* Date (available | created | dateAccepted | dateCopyrighted | dateSubmitted | issued | modified | valid)
+
-
* originInfo/dateIssued
+
-
* originInfo/dateCreated
+
-
* originInfo/dateCaptured
+
-
* originInfo/dateOther
+
-
* month
+
-
* year
+
-
* Copyright Year
+
-
* Date - Generic
+
-
* Date of Confernce
+
-
* Date of Publication
+
-
* Date of update/revisou/issuance of database record
+
-
* Former Date
+
-
* Entry Date for Database Record
+
-
* Database Update
+
-
* Year of Publication
+
-
There are several common properties across several citation domains and will certainly be in the citation microformat, the unique instances will need further consideration, otherwise there could be no end to posiblities.  
+
To be added:
 +
* for each property, what equivalent TCMOS, APA, MLA terms/vocabulary is being expressed/captured as researched in the [[citation-formats#styles|citation formats styles]] section.
 +
* transforms from the web citations proposal properties into each of those citation styles.
 +
** for citations of blog posts / articles
 +
** for citations of text notes / tweets
 +
** see examples in wild below for markup samples to style in each of the TCMOS/APA/MLA styles for blog/note citations.
-
There are also several properties (year, month, Year of publication) that can be extracted from another source. Therefore, if you only encode a more specific property such as; Date of Publication, you can extract the 'year of publication' from that. Since the date-time format we are modeling after is the ISO date-time format, just the Year portion is an acceptable date. So if you ONLY know the year of publication, the you can form a valid 'Date of Publication' as a microformat (which inturn is a valid 'year of publication') - you milage may vary when it comes to importing into citation applications.
+
==== web citation additional uses ====
 +
The web citation proposal could be used for simple web-to-off-web citation use cases. As suggested by Ed Summers, dropping the hyperlink to the cited web article provides a simple off-web citation:
-
...
+
<source lang=html4strict>
 +
<span class="h-cite">
 +
  <time class="dt-published">YYYY-MM-DD</time>
 +
  <span class="p-author h-card">AUTHOR</span>:
 +
  <cite class="p-name">TITLE</cite>
 +
</span>
 +
</source>
-
It seems to me that these can be collapsed to maybe one or two different date properties. As far as the specific human readable formatting of the date, that can be chosen per whatever the presentation style guide says, and the [[datetime-design-pattern]] used to simplify the markup. - Tantek
+
Next steps:
 +
* Try such markup with actual content being published on the web (perhaps a bibliography, list of papers in a resume, etc.)
 +
* See how it works/feels there
 +
* Determine what seems to be missing.  
 +
* See if the "p-publisher" property helps in some web-to-off-web citation use cases.
 +

* Every blog post on http://tantek.com has a text field for copying h-cite markup for that blog post.
 +
* <cite class="h-cite">[http://tantek.com/2012/353/b1/why-html-classes-css-class-selectors Why you should say HTML classes, CSS class selectors, or CSS pseudo-classes, but not CSS classes]</cite> has a couple of interesting uses of h-cite:
 +
** properties used: p-name, u-url, p-author, p-publication, dt-published, dt-accessed (basically all proposed properties except p-content!)
 +
** additional experimental property: p-x-translation - which refers to a nested h-cite with its own implied p-name and implied u-url.

* <cite class="h-cite">[http://christopheducamp.com/blog/test-indieweb-parvenir-a-posser-un-article-vers-twitter/ Test #IndieWeb : Parvenir à « POSSEr » un article vers Twitter]</cite> has an h-cite of a short note:

'''Seasons'''
+
==== web citation references ====
-
Some journals have seasonal issues (e.g. "Summer 2006 edition") instead of, or as well as, editions labelled by month or other calendar-date. [[User:AndyMabbett|AndyMabbett]] 05:05, 4 Nov 2006 (PST)
+
I've been iterating on this design for some time, however, first publicly proposed it as the result of an interactive web citation design discussion during IndieWebCamp2012:
 +
* <span class="h-cite"><time class="dt-published">2012-07-01</time> <span class="p-publisher">IndieWebCamp2012</span>: <cite class="p-name">[http://indiewebcamp.com/2012/Academic_Citations_Web Academic Citations for the Web]</cite></span>
-
== Tags ==
 
-
Some of the citation formats has a place for 'keywords' or 'generic tags', etc. This might be a good place to re-use the [http://microformats.org/wiki/rel-tag RelTag microformat]. The downside would be that they are then forced to be links, which might be the correct way to mark-up these terms.
 
-
== MARC / MODS / Dublin Core ==
+
----
-
The MODS ([http://www.loc.gov/standards/marcxml/Sandburg/sandburgmods.xml example]) and Dublin Core ([http://www.loc.gov/standards/marcxml/Sandburg/sandburgdc.xml example]) transformations of MARC21 may contain some useful ideas.

=== A Prescriptive Proposal ===

Here's a first attempt at rewriting the linked examples in XHTML (written in response to a [http://microformats.org/discuss/mail/microformats-discuss/2005-December/002438.html mailing list query about encoding book information with microformats]):
+
Here is a proposal which was derived from what one actually has to give as information in a citation in university work. (I don't know where to put that, so I put it right here.)
-
<pre><nowiki>
+
First, we need a frame, let's say "hcitation". Multiple citations can be put in a "hcitation" frame. Inside there, we need to describe the type of citation; I suggest "monograph", "anthology", "periodical" , "reference", "thesis" , "standard", "internet", or "specialist".

== Basic Citation Stuctures ==
+
If a "label" was used to refer to the resource in the text (often in square brackets) it can be named so.
-
There are basic structures to any citation, this is an overview of some of the types
+
-
[http://www.users.muohio.edu/darcusb/misc/citations-spec.html http://www.users.muohio.edu/darcusb/misc/citations-spec.html]
+
 +
Here comes the list of field names we need: "article", "atime", "author", "ctime", "department", "edition", "editor", "eligibility", "employer", "number", "overalltitle", "pagerange", "part", "place", "publisher", "subseries", "title", "type", "url", "volume", "volumetitle", "year".
-
== Concerns not addressed by existing formats ==
+
The field "page" is to mark up which page you actually quote from. Marking up whatever as "prefix" should give you a hint that this is to be put at first place, but not to refer to when sorting. E.G. "The" should be marked as "prefix" either in "The Crocodile" and also in "Crocodile, the".
-
There are some aspects '''NOT adequately''' covered by existing formats. I have addressed this issue on the OpenOffice.org wiki page, too. [see http://wiki.services.openoffice.org/wiki/Bibliographic_Database for an extending discussion, the paragraph on ''Reference Types'']

This table shows what has to go together. Numbers give the typical ordered structure of the values. Other Information than given here (eg.

These issues pertain mainly to '''Errata''', '''Comments and Authors Reply''' and '''Article Retractions'''.
+
==== Sample Usage ====
-
* a bidirectional link could be necessary to implement these features (original article <=> eratum, reply, retraction letter)
+
-
* '''IMPORTANT: Errata'''
+
-
** Erata: one or more Corrections might be posted in various issues of the journal
+
-
** this is usually cited as: Orininal Article Citation Data (Correction available in ''Journal, Issue Nr, Year, Pages'') (repeat for more than one correction)
+
-
** it is possibly never cited alone
+
-
** there should be a link to the original article, while the original article should contain a link to this ''Errata''
+
-
* '''IMPORTANT: Commentary and Author Reply'''
+
-
** similar to Errata, there might be one or more Comments and Author Replys; this should be stored, too
+
-
** however, it is usually not included in the original citation
+
-
** it might be used however in a citation, but I do not know exaclty how to cite it optimally (original article should be provided as well)
+
-
* '''IMPORTANT: Article Retraction'''
+
-
** an article may be retracted because of plagiarism or some other flaw
+
-
** this should not be used any further in the research
+
-
** however, it might be used e.g. for an article on plagiarism or flawed research
+
-
** there should be therefore one field storing this information, too, and a link to:
+
-
** the published withdrawal letter (which explains why the article was retracted)
+
-
* this issue may need a time-controlled event
+
<pre><nowiki>
-
* '''IMPORTANT: electronic publishing ahead of print (EPUB)'''
+
<h1>The Bibliography</h1>
-
** more and more articles are initially posted online, before the published article gets actually printed
+
-
** How should this be used/cited?
+
-
** Is this changed, after the print version becomes available?

== Outstanding Issues ==
 
-
The 3 main points i (Brian) came across so far are:
 
-
1) IDENTIFIERS
 
-
2) FORMAT TYPES
 
-
3) NESTING
 
-
1) In hCard/hCalendar there is a UID field. Added with URL it makes for a great unique identifier. There are loads of other identifers besides URL, ISBN, LOC call number, SKU, ISSN, etc. Many of these are unique in their domain, but not globally unique. So how to they get marked-up? Much like the hCard TEL/ADR properties, we can use something like:
 
-
<pre>
 
-
<nowiki>
 
-
<div class="uid"><span class="type">ISBN</span>: <span
 
-
class="value">123456</span></div>
 
-
</nowiki>
 
-
</pre>
 
-
This makes the encoding the most extensible... if we start use class="isbn" then it is an enumerated list, with class="type" it is open ended.
 
-
2) I keep mis-using "format", format is the medium - hardback, softback. The TYPE (there probably is a better word - container?) is book, article, conference, manifesto, etc. Much like the identifers we can make an enumerated list of values, class="book", class="article", but that boxes us in, whereas something like: <pre><nowiki><span class="type">article</span></nowiki></pre> leaves things more open.
+
----
-
3) Nesting citation data in a citation. The ability to nest the same microformat inside itself is something that other microformats don't explicitly handle.
+
=== XHTML Structure ===
 +
With my exprience working X2V and hCa* has taught me what elememts are easy to find and which are not. Since the Citation microformat is very new it is possible to not make a lot of the same errors twice and to make things easier for extracting application to find and imply certain properties.
-
The two options are:
+
* There should be some sort of 'root node' that implies all child elements are for the hCitation microformat.
-
i) Using class="book"
+
* Since most people will have multiple citations there should be away to represent each hCitation object as a unqiue block independent of another. This is to keep the parse from finding 'author' and applying that to all citations. Each citation should be in a container (class="hcite") that is separated from others.
-
<pre>
+
* Perhaps class="hcite" with <code>&lt;cite&gt;</code> recommended as the root element. E.g. <code>&lt;cite class="hcite"&gt;</code>  
-
<nowiki>
+
-
<div class="hcite">
+
-
<div class="book">
+
-
  <span class="fn">Book Title</span>
+
-
  <div class="chapter">
+
-
    <span class="fn">Chapter Title</span>
+
-
  </div>
+
-
</div>
+
-
</div>
+
-
</nowiki>
+
-
</pre>
+
-
This makes things easy to nest and to figure out exactly what is
+
'''Note: This section was the original content of the document. Since then, class='hcite' has been agreed on as the root class name. See  [http://microformats.org/wiki?title=citation-brainstorming#.27hcite.27_as_Root_Element_name explanation].'''
-
associated with what, but the downside is that we have enumerated
+
-
lists of values for the class properties.
+
-
ii) using the TYPE for book
 
-
<pre>
 
-
<nowiki>
 
-
<div class="hcite">
 
-
<div class="type">book</div>
 
-
<span class="fn">Book Title</span>
 
-
<div class="type">chapter</div>
 
-
<span class="fn">Chapter Title</span>
 
-
</div>
 
-
</nowiki>
 
-
</pre>
 
-
now the class="fn" is not nested inside the class="book" or
 
-
class="chapter" so there would have to be some other mechanism to
 
-
associate the data with the type.

==== Notes about missing / changed fields in the schema ====
+
=== This and That ===
 +
After reading through alot of different citation encoding formats, i noticed that each format was being used in one of two ways. It was either to describe the Current page (THIS.PAGE) or being used to encode references that point to external resources (THAT.PAGE)
-
This section lists fields that are intentionally ''not'' included in the straw schema, or are not represented directly, and links to discussion about each.
+
The informatation being encoded was identical for both resources (author, date, name, etc) they just reference different things. For this microformat, i'm not sure if we want to try to solve both problems, or just one? The meta tags in the head element would be the ideal place for information about the THIS.PAGE, but that is not in following with the ideals of microformats where information is human-readable. The THAT.PAGE idea where a list of references is at the end of a document in the form of a bibliography is more inline with the ideals of a microformat where the data is human-readable. That doesn't mean that data about the current document shouldn't be human-readable, so some of the same properties used to reference extermal resources can be used for the current document (THIS.PAGE). To do this a different root item could be used and transforming applications could either extract the citation data about the current page, or information about this page's references.
-
* date copyrighted ([http://microformats.org/wiki?title=citation-brainstorming#Date_Fields explanation])
+
This is open for discussion, but either way, i believe that the properties used to describe a page will be the same for both THIS and THAT. [http://suda.co.uk/ brian suda]
-
=== Examples ===
+
==== More on This and That ====
 +
Citation microformats are being explored as a possibility for citing genealogical information at [http://eatslikeahuman.blogspot.com Dan Lawyer's blog].
-
Markup examples using the above format:
+
This is a case where frequently the citation would refer to (THIS.PAGE), but would have nested within it a reference to (THAT.PAGE), possibly a few levels deep. For instance, a web page might contain data extracted from a microfilm of a census. The citation would need to include information about the web page, information about the microfilm, and information about the census. Genealogical citations are expected to include the repository (where can this book or microfilm be found. Is this the same as ''venue''?). So, at each level the information should contain the repository of the referenced item. A nesting (recursive) mechanism for citation microformats would be useful in this case. Is this the function of the "container" element in the Straw Format?

Here's a first attempt at rewriting the linked examples in XHTML (written in response to a [http://microformats.org/discuss/mail/microformats-discuss/2005-December/002438.html mailing list query about encoding book information with microformats]):

</pre>

-

-
Note: the "format" property above is incorrect. Format would refer more the physical characteristics of an item, rather than its type or genre (e.g. "article", "book", etc.). I'd rather have the main class for the li be "article" in this context, than the fairly meaningless "citation."  Of course, one could have both, which would be fine too. -- bruce

Note: Could we use ROLE from hCard to identify editors, translators, authors, etc?

* Missing a URL/URI/IRI/UID etc. field example (ISBN for Book).
+
-
* Does the "copyright" class conflict with [http://www.whatwg.org/specs/web-apps/current-work/#class WHATWG's definition]?
+
-
* WRT Bruce's comment, I'm currently using class="article citation" for my writing, as it has the most flexibility with CSS styles for titles (e.g. Book titles .citation>.fn must be italicized, while article titles must not, their container should).
+
-
* Speaking of containers, we need an "in" or "collection" field for journal articles or articles-in-books, or is that covered by "publisher"?

== comparison and use of other microformats ==
 +
=== Citation vs. [[media-info]] ===
 +
What distinguishes a cite from say [[media-info]] (e.g. [[media-info-examples]]) is that a cite is a reference to something explicitly external to the current piece of content or document, whereas [[media-info]] describes information about content embedded or inline in the current document.

==== Citing a magazine article ====
+
=== Date Formatting ===
 +
Since microformats are all about re-use and the accepted way to encode Date-Time has been pretty much settled, then this is a good place to start when dealing with all the different date citation types.
-
needs an example
+
These are all the different fields from various citation formats that are of temporal nature:
 +
* Date (available | created | dateAccepted | dateCopyrighted | dateSubmitted | issued | modified | valid)
 +
* originInfo/dateIssued
 +
* originInfo/dateCreated
 +
* originInfo/dateCaptured
 +
* originInfo/dateOther
 +
* month
 +
* year
 +
* Copyright Year
 +
* Date - Generic
 +
* Date of Confernce
 +
* Date of Publication
 +
* Date of update/revisou/issuance of database record
 +
* Former Date
 +
* Entry Date for Database Record
 +
* Database Update
 +
* Year of Publication
-
==== Citing a Patent ====
+
There are several common properties across several citation domains and will certainly be in the citation microformat, the unique instances will need further consideration, otherwise there could be no end to posiblities.
-
Drawn from this [http://microformats.org/wiki/citation-examples#U.S._Patent example from Wikipedia]:
+
There are also several properties (year, month, Year of publication) that can be extracted from another source. Therefore, if you only encode a more specific property such as; Date of Publication, you can extract the 'year of publication' from that. Since the date-time format we are modeling after is the ISO date-time format, just the Year portion is an acceptable date. So if you ONLY know the year of publication, the you can form a valid 'Date of Publication' as a microformat (which inturn is a valid 'year of publication') - you milage may vary when it comes to importing into citation applications.

==== Citing a conference publication====

It seems to me that these can be collapsed to maybe one or two different date properties.  As far as the specific human readable formatting of the date, that can be chosen per whatever the presentation style guide says, and the [[datetime-design-pattern]] used to simplify the markup. - Tantek

Some of the citation formats has a place for 'keywords' or 'generic tags', etc. This might be a good place to re-use the [http://microformats.org/wiki/rel-tag RelTag microformat]. The downside would be that they are then forced to be links, which might be the correct way to mark-up these terms.

</nowiki></pre>
+
During the WWW2005 Developer's Day [[microformats]] track, Rohit Khare gave a [[presentations|presentation]] where he discussed the microformats [[process]], and then did  a quick demonstration wherein a bunch of us got on a shared Subethaedit document, and brainstormed some thoughts on what an "hBib" bibliography citation microformat would look like. Rohit placed the [http://cnlabs.commerce.net/~rohit/hBib%20Discussion.html document on his Commercenet site].

==== Citing an external website ====

* Avoid re-keying references

+
   
   
-
<pre><nowiki>
+
The fundamental problem was discussed in terms of display - the ability to transform XHTML+hBib into the many journal-specific formats. For example, how to display "et.al" when all authors are present in the source, and how to re-order the elements if a style defines a set order of elements that conflicts with the ordering in the source. Using hCard for authors was agreed on, and the beginnings of an example were shown.

=== Discussion of Straw Format elements ===
+
-
 
+
-
This section is to provide explanations for posterity about the elements of the straw format, linking to discussions on the list and elsewhere if possible.
+
-
 
+
-
==== 'hcite' as Root Element name ====
+
-
 
+
-
This discussion took place in January of 2007, with [http://microformats.org/discuss/mail/microformats-discuss/2007-January/008098.html voting occurring on the mailing list].
+
-
 
+
-
It was decided to use 'hcite' as the root element's class-name for uniqueness and to reflect a trend in using 'h' to start microformat names.
+
-
 
+
-
==== The URI Element ====
+
-
 
+
-
It was decided to use URI for both http links to available copies or URNs.
+
-
This encompasses URLs that link directly to online copies as well as through resolvers using URIs such as urn:isbn: 0521890012
+
-
 
+
-
See the discussion from [http://microformats.org/discuss/mail/microformats-discuss/2006-November/007390.html November] and [http://microformats.org/discuss/mail/microformats-discuss/2006-December/007403.html December].
+
-
 
+
-
==== Date Fields ====
+
-
 
+
-
Brian's original straw format had three date fields, "accessed", "copyrighted", and "published".
+
-
After examining the examples of usage on the web, it was clear that 'copyrighted' was not used in the examples we have.
+
-
It was used once, but without a corresponding 'published' field (OCLC WorldCat), and it seems in that case to be used as
+
-
an equivalent to 'published'.
+
-
 
+
-
I updated the straw citation to include only 'accessed' and 'published' on January 31. --[[User:Mike|Mike]] 00:26, 31 Jan 2007 (PST)
+
-
 
+
-
I've mentioned more than once that "date-published" is misleadingly specific; too much for real world citations. Consider that many books are published in the year preceding their copyright date, which is in fact the date used for citation. I'd prefer just "date" and "date-accessed" as a first cut. --[[User:BDarcus|Bruce]] 3 Feb 2007
+
-
 
+
-
See the discussion from the [http://microformats.org/discuss/mail/microformats-discuss/2007-January/008175.html 'dates' thread on the list].
+
-
 
+
-
==== Container ====
+
-
 
+
-
Discussion about how to represent containing relationships is on the thread [http://microformats.org/discuss/mail/microformats-discuss/2007-March/thread.html 'nesting container elements']
+
-
 
+
-
== Old straw format discussion ==
+
-

Saved here so that I'm not just deleting people's comments.
+
-
 
+
-
 
+
-
=== Mike straw format suggestion (Deprecated) ===
+
-
 
+
-
In the interests of starting debate and having something concrete to fix, I suggest the following structure for a format. It is probably very incomplete and I claim no microformat expertise. I'm just trying to follow existing patterns. Comments and ridicule are both solicited. -Mike
+
-
 
+
-
'''NOTE:''' This format is here for historical reference. Because it was not based on existing examples, I've deprecated it and contributed examples to Brian's format. If you feel that any missing elements in here should be in the final format, find examples for them and contribute to Brian's schema. Thanks! --[[User:Mike|Mike]] 18:22, 12 Oct 2006 (PDT)
+
-
 
+
-
==== In General ====
+
-
 
+
-
The ''citation'' format is based on a set of fields common to many bibliographic data formats, which are often implied by standard citation display styles but not explicitly marked up in practice on the web.
+
-
 
+
-
==== Schema ====
+
-
 
+
-
The citation schema consists of the following:
+
-
 
+
-
* cite
+
-
** title: required, text (class = fn)
+
-
** subtitle: optional, text
+
-
** authors: optional, use hCard
+
-
** publication date: optional
+
-
** link(s) to instantiations, optional, url or use rel-enclosure? (class=url)
+
-
** UID, optional (for ISBN, DOI - use existing uid class) | permalink
+
-
** series (aka volume/issuenum) , optional (''not as sure how to handle these - suggestions?'')
+
-
** pages: startpage & endpage, optional, text
+
-
** venue, optional (hCard)
+
-
** publisher, optional (hCard)
+
-
** container: optional (nested hCite)
+
-
** abstract, optional (blockquote + class="abstract" ?)
+
-
** notes, optional (blockquote + class="notes" ?)
+
-
** keywords, optional (rel-tag)
+
-
** image, optional (for inclusion inline, unlike the url)
+
-
** copyright, optional (rel-license)
+
-
** ''what else am I missing?''
+
-
*** language, optional
+
-
 
+
-
''Looks good, but I question the use of hCard for names. Due to ambiguity issues, requring hCard would lead to extra markup in order to apply just a name, hence [http://microformats.org/discuss/mail/microformats-discuss/2006-March/003487.html the need for a root element]. We should extract the N optimization of hCard like we did with adr, in order to ease this problem.'' --[[User:RCanine|Ryan Cannon]]
+

+
-
Perhaps a Retrieved Date or Access Date would be appropriate for citing online resources. For example at http://www.crlt.umich.edu/publinks/facment_biblio.html

==== Discussion about citing legal cases ====
+
-
 
+
-
Here's some info I found about citing law:
+
-
 
+
-
I'm not a lawyer, so I'm relying on the published [http://www.legalbluebook.com "blue book" standard], at least the only part of it I can get without paying $25. I'd be happy to hear improvements from experts in the field - how do lawyers mark up references to case law in HTML now?
+
-
 
+
-
From groklaw.net and eff.org, I find mostly just links to PDFs with the name of the case as the link text. Or just this, from EFF:
+
-
<pre><nowiki>
+
-
<h1>The Betamax Case</h1>
+
-
<h2>Sony Corp. of America v. Universal City Studios, 464 U.S. 417 (1984)</h2>
+
-
</nowiki></pre>
+
-
 
+
-
From an example at the sample bluepages: http://www.legalbluebook.com/pdfs/bluepages.pdf
+
-
5 basic components:
+
-
*1 name of the case (citation title)
+
-
*2 published source in which case may be found (citation containing publication?)
+
-
*3 a parenthetical indicating the court and year of decision (citation venue?)
+
-
*4 other parenthetical information, if any (citation notes?)
+
-
*5 subsequent history of the case, if any (citation notes?)
+
-
 
+
-
Here's two examples from the bluebook. Note that there are very strict rules about abbreviations in that source!

Current revision


Part of the overall effort to develop a citation microformat.

Contents

Use Cases

To focus the discussion, please add use cases below that will help show what problems the citation microformat will be solving.

Use cases for both publishing and consuming citation information can help to focus citation brainstorming on efforts that provide real world utility to users.

For now, please add any uses cases you think of, however common or obscure (feel free to note opinions as to expected/known frequency of use of such use cases).

improve web citations

Articles on the web often cite other online articles with permalinks (e.g. blogs quoting other resources, including blogs). Such web citations could be improved both in content and interaction in a number of useful ways:

Additional useful rich citation enhancements:

I read this

A reader wants to collect a set of things they've read (e.g. on the web), perhaps for the purposes of cataloging them, adding notes, and using the information to generate later citations, potentially in other forms, such as BibTeX or Docbook, for inclusion in a publication of their own.

If web articles (e.g. blog posts) contained discoverable descriptions of self-citations (e.g. permalinks plus authorship), browsers/aggregators could both automatically collect these, perhaps as part of an enhanced browser history functionality, or allow explicit collection, e.g. bookmarking with additional structure.

Notes: In this case, it isn't important to the user what style the citation takes as displayed on the page where they find it. What *is* important is that it contains enough information to allow generation of the format they will ultimately re-publish it in. This implies that it may be worthwhile to err a little on the side of verbosity, but at most enough to provide typical TCMOS/APA/MLA citations.

collect further reading

Was part of Acquiring reference information from the web.

A reader finds a list of citations (e.g. a paper's bibliography, an author's papers page, results of a search for academic papers), and wants to add them to a queue of things they'd like to read, perhaps as part of further research on whatever subject/person they were reading/researching.

Marking up the list of citations with a microformat would enable to browsers/aggregators to present an explicit list of structured citations with a user interface for one-click addition to a read it later list (or a local reference database).

Links to downloadable full representations of the cited work (e.g. link to the PDF of a journal article, or to a music file) would help the reader find cited works, and perhaps even have their browser/aggregator prefetch/cache/download them.

Subscribing to reading lists, periodicals, etc

I would like to be able to leverage my news aggregator with hAtom to subscribe to a remote source for citation information, for example:

Aggregating reading lists and reviews

A citation microformat-specific aggregator could provide a decentralized version of CiteULike. Libraries, authors, research groups, and publishers could mark up their collections, while other people on weblogs or review sites could add tags and reviews.

At least, having a well-adopted microformat would make writing tools like CiteULike much better, since it relies in some cases on screen-scraping publisher web-sites.

Cut & Paste from web pages

Capturing/copying HTML from web pages for use in other applications (especially when those apps present HTML as output), such as pasting into Word, or a specialized application like Google Notebook, Onfolio or Kaboodle. When such captures are made, it makes sense to keep track of the full citation data, including the date it was accessed, which may or may not be the date it was published.

Finding in Library

Find a copy of the cited work in a nearby library (as with OpenCOinS).

Buy a copy

Find the cited work on, for example, Amazon or ABE; or subscribe to a journal via its own website.

Find reviews

Find third-party reviews of the cited work.

Give citation data for the page being visited

Adding a class of, say, "self" to an attribute of the proposed strawman would allow users (or user agents) to extract the data required to cite the page being visited, when referring to it elsewhere. There would be the added advantage of allowing the citation to be ignored by any parser which might be building a "tree" of citations, and preventing the setting up of an infinite loop.

For evidence of published "self citation" data (albeit on a secondary page) see the "cite this article" link on any Wikipedia entry, e.g. [1] from [2].

See also Proposal to include on-page citation data in Wikipedia

Cite a journal on Wikipedia

if you want to cite a [biomedical journal] journal article on Wikipedia [...] you can export a correctly-formatted citation for Wikipedia from HubMed using unAPI... http://hublog.hubmed.org/archives/001408.html

principles

Principles help guide and compare various different brainstorming proposals.

In the first three years of development the citation microformat effort generated a number of brainstorm proposals without clear consensus or adoption of any of them in particular. Thus any new (2012+) proposals must be written with references to particular principles for each design decision, justifying why/how the new proposal is an improvement upon previous proposals.

Principles to use:

Semantic HTML Design Principles

  1. Reuse the schema (names, objects, properties, values, types, hierarchies, constraints) as much as possible from pre-existing, established, well-supported microformats.
  2. When new schema are needed, reuse the schema (names, objects, properties, values, types, hierarchies, constraints) as much as possible from pre-existing, established, well-supported other formats/standards by incorporation, following the microformats naming-principles. Re-do constraints expressed in the source standard from the perspective of microformats design principles and designed primarily for web authoring. Informatively mention source standard for reference purposes.
    1. For types with multiple components, use nested elements with class names equivalent to the names of the components.
    2. Plural components are made singular, and thus multiple nested elements are used to represent multiple text values that are comma-delimited.
  3. Use the most accurately precise semantic HTML building block for each object etc.
  4. Otherwise use a generic structural element (e.g. <span> or <div>), or the appropriate contextual element (e.g. an <li> inside a <ul> or <ol>).
  5. Use class names based on names from the original schema, unless the semantic HTML building block precisely represents that part of the original schema. If names in the source schema are case-insensitive, then use an all lowercase equivalent. Components names implicit in prose (rather than explicit in the defined schema) should also use lowercase equivalents for ease of use. Spaces in component names become dash '-' characters.
  6. Finally, if the format of the data according to the original schema is too long but still human readable/listenable, use <abbr> instead of a generic structural element, and place the literal longer data into the 'title' attribute (where abbr expansions go), and the briefer equivalent into the contents of the element itself. If however, the format of the literal longer data data is not human-friendly, instead of <abbr>, use the value-class-pattern or HTML5 <time>/<data> elements as most semantically appropriate.

Brainstorm proposals should take into account the Semantic HTML Design Principles.

semantic elements to consider

One of the guiding principles of Microformats is to encourage the use of the most precisely semantically rich element to describe each node (Point 2 of Semantic HTML Design Principles: Use the most accurately precise semantic HTML building block for each object etc). Since we are dealing with HTML and citations, several elements are candidates to be used to enrich the semantic meaning. CITE, BLOCKQUOTE, Q, A, (are there more?)

Main article: h-cite

This brainstorm has now been moved to a draft microformat:

The remainder of this brainstorm proposal is left here for historical purposes:

The web citations proposal uses a smaller, simpler set of only eight properties to solve the specific problem of how to markup citations in an article on the web that refers to other articles on the web. Offline to offline, and online to offline references are specifically not addressed.

web citations background

This work is based on how existing citation format styles (APA, MLA, TCMOS) represent references to articles on the web, and is designed to match the implied schema of those styles. The web citations proposal defines how to markup such reference representation styles in order to satisfy the use-cases above.

web citation illustrative example

Here is a simple minimal abstract web citation example:

<span class="h-cite">
  <time class="dt-published">YYYY-MM-DD</time> 
  <span class="p-author h-card">AUTHOR</span>: 
  <cite><a class="u-url p-name" href="URL">TITLE</a></cite>
</span>

web citations vs previous proposals

I think the biggest problem with all previous proposals is that they tried to do too much. They didn't design a citation microformat that could be used as a building block, but rather, erred on the side of attempting to describe the myriad types of references to dead-tree resources. They were so over-designed that their authors didn't even dogfood them on their own sites. -- Tantek 00:56, 7 August 2012 (UTC)

A primary goal of the web citation effort is to both start small, and always "make small possible", that is, no matter how it is extended, continue permitting very small meaningful citations with perhaps only 2-3 properties (e.g. date published, author, name of work).

web citations design principles

Principles driving this proposal:

web citation property details

(stub)

All web citation properties are derived from the implied schema in existing citation styling guides for citing permalinks to articles and short text notes online.

Date-time properties (dt-published, dt-accessed) may optionally include time information in addition to the date if relevant to the citation (e.g. when citing short text notes (tweets) of which there may be several in a single day).

To be added:

web citation additional uses

The web citation proposal could be used for simple web-to-off-web citation use cases. As suggested by Ed Summers, dropping the hyperlink to the cited web article provides a simple off-web citation:

<span class="h-cite">
  <time class="dt-published">YYYY-MM-DD</time> 
  <span class="p-author h-card">AUTHOR</span>: 
  <cite class="p-name">TITLE</cite>
</span>

web citation references

I've been iterating on this design for some time, however, first publicly proposed it as the result of an interactive web citation design discussion during IndieWebCamp2012:



A Prescriptive Proposal

(Contributed 2008-07-09 by User:Paramaeleon to the citation page). Tantek 19:31, 27 July 2012 (UTC)

Here is a proposal which was derived from what one actually has to give as information in a citation in university work. (I don't know where to put that, so I put it right here.)

First, we need a frame, let's say "hcitation". Multiple citations can be put in a "hcitation" frame. Inside there, we need to describe the type of citation; I suggest "monograph", "anthology", "periodical" , "reference", "thesis" , "standard", "internet", or "specialist".

If a "label" was used to refer to the resource in the text (often in square brackets) it can be named so.

Here comes the list of field names we need: "article", "atime", "author", "ctime", "department", "edition", "editor", "eligibility", "employer", "number", "overalltitle", "pagerange", "part", "place", "publisher", "subseries", "title", "type", "url", "volume", "volumetitle", "year".

The field "page" is to mark up which page you actually quote from. Marking up whatever as "prefix" should give you a hint that this is to be put at first place, but not to refer to when sorting. E.G. "The" should be marked as "prefix" either in "The Crocodile" and also in "Crocodile, the".

Field Description monograph anthology periodical thesis standard internet specialist
article Name of the Article in question   3 3        
atime Last access time for online resources. Use abbr convention for datetime encoding.     11     5  
author Creator. Use fn or n markup for every single entity. 1 1 1 1   1 1
ctime Date / Last modification. Use abbr convention for datetime encoding.     8     4 5
department special field / faculty       6     3
edition Edition information 6 8     2    
editor Editors of an anthology. Use fn or n markup for every single entity. Add "transl" for translators and "comp" for compilers   4          
eligibility Qualification of a specialist             2
employer Name of university eg.       4     4
number Number 10 12 9   1    
overalltitle Overall Title / Title of series 9 11         8
pagerange Page range of an article in an anthology / periodical   13 10        
part Part of article (if having several parts)     4        
place Place of publication 7 9   5      
publisher Publication house 8 10          
subseries Name of subseries, if any     6        
title The main title. Anthology: name of anthology. Periodical: name of periodical 3 5 5 3 3 3 6
type Type (type of thesis or type of utterance (radio interview, e-mail, ...) of a specialist)       7     7
url URL     12     6  
volume Volume information (eg. Vol. 22) 4 6 7        
volumetitle Volume title 5 7          
year Year of appearance. 4 digit year. Use abbr convention for datetime encoding. 2 2 2 2   2  

This table shows what has to go together. Numbers give the typical ordered structure of the values. Other Information than given here (eg. ISBN, ...) actually has not to be put into citations, students would recive negative evaluations if they do so. (I hope this will help somehow. sorry for bad english.)

XHTML Structure

With my exprience working X2V and hCa* has taught me what elememts are easy to find and which are not. Since the Citation microformat is very new it is possible to not make a lot of the same errors twice and to make things easier for extracting application to find and imply certain properties.

Note: This section was the original content of the document. Since then, class='hcite' has been agreed on as the root class name. See explanation.



how to use with HTML5

Per Theresa O'Connor's email to public-html: Add a section in the citation microformat describing how to use the citation microformat in HTML5, including optional use of HTML5's <time> element and microdata feature. Encourage HTML5 to drop the "BibTeX" predefined microdata vocabulary and reference an updated citation microformat spec instead. Tantek



OCLC's WorldCat for titles

Question: what about using something like OCLC's WorldCat for linking titles? - Tim White



This and That

After reading through alot of different citation encoding formats, i noticed that each format was being used in one of two ways. It was either to describe the Current page (THIS.PAGE) or being used to encode references that point to external resources (THAT.PAGE)

The informatation being encoded was identical for both resources (author, date, name, etc) they just reference different things. For this microformat, i'm not sure if we want to try to solve both problems, or just one? The meta tags in the head element would be the ideal place for information about the THIS.PAGE, but that is not in following with the ideals of microformats where information is human-readable. The THAT.PAGE idea where a list of references is at the end of a document in the form of a bibliography is more inline with the ideals of a microformat where the data is human-readable. That doesn't mean that data about the current document shouldn't be human-readable, so some of the same properties used to reference extermal resources can be used for the current document (THIS.PAGE). To do this a different root item could be used and transforming applications could either extract the citation data about the current page, or information about this page's references.

This is open for discussion, but either way, i believe that the properties used to describe a page will be the same for both THIS and THAT. brian suda

More on This and That

Citation microformats are being explored as a possibility for citing genealogical information at Dan Lawyer's blog.

This is a case where frequently the citation would refer to (THIS.PAGE), but would have nested within it a reference to (THAT.PAGE), possibly a few levels deep. For instance, a web page might contain data extracted from a microfilm of a census. The citation would need to include information about the web page, information about the microfilm, and information about the census. Genealogical citations are expected to include the repository (where can this book or microfilm be found. Is this the same as venue?). So, at each level the information should contain the repository of the referenced item. A nesting (recursive) mechanism for citation microformats would be useful in this case. Is this the function of the "container" element in the Straw Format?



MARC / MODS / Dublin Core

The MODS (example) and Dublin Core (example) transformations of MARC21 may contain some useful ideas.

Here's a first attempt at rewriting the linked examples in XHTML (written in response to a mailing list query about encoding book information with microformats):

<div class="book" lang="en">
  <h3 class="fn">Arithmetic /</h3>
  <p>By <span class="creator"><span class="fn">Sandburg, Carl</span>,
     <span class="date">1878-1967</span></span>,
     and <span class="illustrator">Rand, Ted</span></p>
  <p>Publisher: <span class="publisher"><span class="fn">Harcourt Brace Jovanovich</span>,
     <span class="locality">San Diego</span></span></p>
  <p>Published: <span class="issued">1993</span></p>
  <p class="description">A poem about numbers and their characteristics. Features
     anamorphic, or distorted, drawings which can be restored to normal by viewing
     from a particular angle or by viewing the image's reflection in the provided
     Mylar cone.</p>
  <p class="note">One Mylar sheet included in pocket.</p>
  <p>Subjects:</p>
  <ul>
    <li class="subject">Arithmetic</li>
    <li class="subject">Children's poetry, American.</li>
    <li class="subject">Arithmetic</li>
    <li class="subject">American poetry</li>
    <li class="subject">Visual perception</li>
  </ul>
</div>

comparison and use of other microformats

Citation vs. media-info

What distinguishes a cite from say media-info (e.g. media-info-examples) is that a cite is a reference to something explicitly external to the current piece of content or document, whereas media-info describes information about content embedded or inline in the current document.

Date Formatting

Since microformats are all about re-use and the accepted way to encode Date-Time has been pretty much settled, then this is a good place to start when dealing with all the different date citation types.

These are all the different fields from various citation formats that are of temporal nature:

* Date (available | created | dateAccepted | dateCopyrighted | dateSubmitted | issued | modified | valid)
* originInfo/dateIssued
* originInfo/dateCreated
* originInfo/dateCaptured
* originInfo/dateOther
* month
* year
* Copyright Year
* Date - Generic
* Date of Confernce
* Date of Publication
* Date of update/revisou/issuance of database record
* Former Date
* Entry Date for Database Record
* Database Update
* Year of Publication

There are several common properties across several citation domains and will certainly be in the citation microformat, the unique instances will need further consideration, otherwise there could be no end to posiblities.

There are also several properties (year, month, Year of publication) that can be extracted from another source. Therefore, if you only encode a more specific property such as; Date of Publication, you can extract the 'year of publication' from that. Since the date-time format we are modeling after is the ISO date-time format, just the Year portion is an acceptable date. So if you ONLY know the year of publication, the you can form a valid 'Date of Publication' as a microformat (which inturn is a valid 'year of publication') - you milage may vary when it comes to importing into citation applications.

...

It seems to me that these can be collapsed to maybe one or two different date properties. As far as the specific human readable formatting of the date, that can be chosen per whatever the presentation style guide says, and the datetime-design-pattern used to simplify the markup. - Tantek


Important Sometimes we need a date range and not simply a date (e.g. 4-6 May 2006). See Conference Citation examples later on this page. - Discoleo

Seasons Some journals have seasonal issues (e.g. "Summer 2006 edition") instead of, or as well as, editions labelled by month or other calendar-date. AndyMabbett 05:05, 4 Nov 2006 (PST)

Tags

Some of the citation formats has a place for 'keywords' or 'generic tags', etc. This might be a good place to re-use the RelTag microformat. The downside would be that they are then forced to be links, which might be the correct way to mark-up these terms.

past discussions

Original hBib Discussion

During the WWW2005 Developer's Day microformats track, Rohit Khare gave a presentation where he discussed the microformats process, and then did a quick demonstration wherein a bunch of us got on a shared Subethaedit document, and brainstormed some thoughts on what an "hBib" bibliography citation microformat would look like. Rohit placed the document on his Commercenet site.

An attempt to summarize and inline the linked document follows. -Mike

Two major goals were outlined by the group:

The fundamental problem was discussed in terms of display - the ability to transform XHTML+hBib into the many journal-specific formats. For example, how to display "et.al" when all authors are present in the source, and how to re-order the elements if a style defines a set order of elements that conflicts with the ordering in the source. Using hCard for authors was agreed on, and the beginnings of an example were shown.

Outstanding Issues
