Girlwithglasses: /* A Prescriptive Propose */ a few basic grammar / spelling errors corrected

<h1> Citation microformat efforts </h1>

This wiki page outlines the overall effort to develop a citation microformat. We are documenting current examples of [http://en.wikipedia.org/wiki/Citation cites/citations] on the web today, their implicit/explicit schemas, and current cite/citation formats, with the intent of deriving a cite microformat from that research.

== Semantic XHTML Design Principles ==
{{semantic-xhtml-design-principles}}

== Example Citations ==
[[citation-examples|Citation Examples]] are citations found in the wild that could benefit from semantic mark-up. This is a growing list of examples from all sorts of places including W3C specifications, RFCs and others. These are the examples which will determine the schema for the citation microformat.

== Known Citation Formats ==
The [[citation-formats|Citation Formats Page]] will be a running tab of known formats for publishing citations.

Eventually, I would like to see a chart of how each value from the implicit schema determined by the [[citation-examples]] is represented in each format, and what formats have additional properties that do not map between them. (For example, Format1 calls 'author' 'author', in format2 'author' is called 'writer'. etc)

== A Prescriptive Proposal ==

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".

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.)

== Issues ==
The [[citation-issues]] page is intended to capture ongoing issues.

== To Do ==
* [[existing-classes|Using existing class names]] and creating new names, create property names for the profile
* Based on implicit schemas in [[citation-examples]], and terms from one or more [[citation-formats]], do some [[citation-brainstorming]] for a simple citation microformat.
* Create additional strawman proposals

== Modularity ==
My hope for this microformat is that it can be a sort of module that can be used in other microformats. Once this is developed and flushed out, citation references could easily be used for publications on a Resume/CV, therefore the citation microformat would be a module (subset) of all the possible Resume Values.

Other Microformats that could use the Citation Module
* [[hresume|hResume]]
* [[work-of-art]]

Other Microformats that the Citation Module will use
* [[hcard|hCard]] encodings for things like Author, Publisher (people and companies)
* [[hatom|hAtom]] encodings as a possible container, and author/date-time properties
* [[rel-tag]] encoding for keywords
* [[rel-license]] encoding for copyright

== References ==
=== Informative References ===

Girlwithglasses: Correcting an error that was causing the page not to render correctly

= Citation Formats =

This page will display several different types of citation format types. The idea is to compare what properties are common amonst all of the formats and which ones should be blended into this microformat.

== Comparison chart ==
The following chart maps the terms from one implementation to another. This is important because if all the properties are introduced to this microformat, then it's possible to map them to a number of different formats. The table currently only uses Dublin Core, MODS, and bibTeX. Each column has all the properties and their equivalent in each format. If there is no corresponding property, the cell is grey. At the bottom of the list are the unique terms to each format. Dublin Core has basic terms and terms that extend the basic ones. If the property is an extension of a basic term it is in ()'s. MODS uses XML, so any sub-properties are listed in their tree form, property/sub-property.

THIS IS NOT DEFINITIVE, any errors should be corrected. More formats will be added to the list as they are mapped.

== Dublin Core Metadata ==
[http://dublincore.org/ Dublin Core] metadata uses a small vocabulary to describe the data.
* contributor
* coverage
* creator
* date
* description
* format
* identifier
* language
* publisher
* relation
* rights
* source
* subject
* title
* type

From those there are specialised types which are just refinements of the previous, for example:

* abstract refines description
* accessRights refines rights

[http://dublincore.org/documents/dc-citation-guidelines/ Guidelines for Encoding Bibliographic Citation Information in Dublin Core Metadata]

== MODS (Metadata Object Description Schema) ==
This is a format developed for the Library of Congress for a bibliographic element set that may be used for a variety of purposes, and particularly for library applications.

[http://www.loc.gov/standards/mods/ http://www.loc.gov/standards/mods/]

(the schema is very big, once i devote the proper time to review it, i will post more about the structure -brian)

== NCBI-NLM Journal Publishing DTD ==

[http://dtd.nlm.nih.gov/publishing/tag-library/2.1/n-fv30.html http://dtd.nlm.nih.gov/publishing/tag-library/2.1/n-fv30.html]

The [http://dtd.nlm.nih.gov/publishing/tag-library/ NLM Journal Publishing DTD] defines the schema used for publishing journal articles as XML. The <pre><citation></pre> element can be placed with paragraphs or within a <pre><ref-list></pre> element at the end of the article.

"Although the DTD does not enforce it, a citation to a journal article should be tagged with as many as possible of the following, so that PubMed Central, CrossRef, or other matching service can make the citation into a live link:

<table border="1">
<tr><td>source</td><td>The title of a journal, book, conference proceedings, etc. that is the source of the cited material. (Note: In PubMed Central processing, this is typically the MEDLINE abbreviation of the journal name.)</td></tr>
<tr><td>article-title</td><td>Title of the article</td></tr>
<tr><td>volume</td><td>Volume of the journal</td></tr>
<tr><td>issue</td><td>Issue of the journal</td></tr>
<tr><td>fpage</td><td>Page number on which the article starts</td></tr>
<tr><td>name</td><td>Name of an author or editor</td></tr>
<tr><td>year</td><td>Year of publication</td></tr>
<tr><td>month</td><td>Month of publication (if present)</td></tr>
<tr><td>day</td><td>Date of publication (if present)</td></tr>
</table>

The other elements (described [http://dtd.nlm.nih.gov/publishing/tag-library/2.1/n-fv30.html here]) may be tagged if desired. Use the <pre><source></pre> element for titles of books, conference proceedings, etc."

== XMLResume ==

== RIS ==

RIS is similar to BibTeX and is handled by most desktop and web-based bibliography management software.

The specification and field types/tags are described at [http://www.refman.com/support/risformat_intro.asp http://www.refman.com/support/risformat_intro.asp]

In particular, see [http://www.refman.com/support/risformat_reftypes.asp the list of different reference types].

== OpenURL ==

OpenURL aka [http://www.niso.org/standards/standard_detail.cfm?std_id=783 Z39.88] defines a standard way of bundling citation data in a URL. It is widely deployed in academic libraries around the world to provide access to licensed content via link resolvers such as [http://www.exlibrisgroup.com/sfx_openurl.htm SFX]. The Context Object in Span ([http://ocoins.info/ COinS]) community standard represents one way to embed OpenURLs in XHTML without including a resolver target. OpenURL also provides an XML encoding.

Example (from a book review written using the Structured Blogging plugin):

<pre><nowiki>
ISBN: 
0679426612
</nowiki></pre>

Another example, a journal this time:
<pre>
<nowiki>

</nowiki>
</pre>

As you can see this isn't very much like semantic XHTML at all. However significant work has gone into defining the set of Key/Encoded Values (KEVs) that can be used in various [http://alcme.oclc.org/openurl/servlet/OAIHandler?verb=ListRecords&metadataPrefix=oai_dc&set=Core:Metadata+Formats types] of citations: [http://www.openurl.info/registry/docs/mtx/info:ofi/fmt:kev:mtx:book book], [http://www.openurl.info/registry/docs/mtx/info:ofi/fmt:kev:mtx:dissertation dissertation], [http://www.openurl.info/registry/docs/mtx/info:ofi/fmt:kev:mtx:journal journal], [http://www.openurl.info/registry/docs/mtx/info:ofi/fmt:kev:mtx:patent patent]. It would be possible to simply provide a standard XHTML bundling for these keys as a microformat.

=== Example ===

<pre>

Using OpenURL in this way would enable third party applications that could, say grab citation metadata from a blog, and without much work fire it off at your university's or public libraries openurl resolver to see if the article is available via a licensed databases. The benefits [http://www.infotoday.com/newsbreaks/nb050801-1.shtml have] [http://www.ariadne.ac.uk/issue43/chudnov/ been] [http://www.wallandbinkley.com/quaedam/?p=30 noted] [http://hublog.hubmed.org/archives/001163.html elsewhere].

== The OpenURL Briefly Explained ==

An OpenURL consists of two independent parts: the ContextObject (or the bibliographic metadata surrounding a citation) and the location of resolver to parse the metadata and present contextual services based on said metadata. The problem is that the term "OpenURL" is also used as a catch-all for all of the independent parts and how they work. This is mainly because it's a catchier term than "Z39.88", which is the [http://www.niso.org/standards/standard_detail.cfm?std_id=783 NISO standard all this is based upon].

The most common representation of the OpenURL ContextObject is seen as arguments in a URL string (which is referred to as "San Antonio Profile 1" -- more commonly SAP1 -- and is represented in Key Encoded Values -- KEVs). This "representation" is independent of the ContextObject (from here on known as CO) itself and is only intended to permit the CO to be transmitted via an HTTP GET request.

There is also SAP2, which is an XML representation of the CO (see: [http://alcme.oclc.org/openurl/servlet/OAIHandler?verb=GetRecord&metadataPrefix=oai_dc&identifier=info:ofi/fmt:xml:xsd:ctx here] for more information) and is a much more human readable format. This still falls outside the scope of microformats, but makes the point that encoding has nothing to do with the CO itself. They are just agreed upon means of conveying the CO to enable machines act upon them consistently.

The ContextObject could be conveyed just as easily in XHTML using attributes, as long as the terms follow the vocabulary defined in the OpenURL framework. The important thing to focus on here is the ContextObject -- the address of the link resolver ''is'' institution-specific and should be handled by a user's (or machine's) activating agent.

However, the link resolver is still a very important component to this whole process. Getting users "appropriate copy" is a very real (and very difficult) problem that libraries are trying to solve. Link resolvers are a pretty efficient means of overcoming this hurdle, so it would make sense to mark up bibiographic citations in a way that link resolvers can easily parse.

I'm not sure the best place for a guide to Z39.80 so please add links as you see fit:

== Implied Schema ==
This is the start of the short list of common properties across documented formats. Once this is finished, there will be a union of Implied schemas between EXAMPLES and IMPLEMENTATIONS and we will see what that looks like. (This currently only covers a few of the formats listed, some documented formats still need to be explored)

* creator (author, editor, translator, contributor) - this can be handled with hCard, but will need an additional property to refine what "creator" means
* publisher (this can also be handled with hCard)
* subject/topics/keywords/categories/genre (there is a rel="tag" microformat)
* Description (abstract, note, tableOfContents)
* typeOfResource/format

common location information
* volume
* issue
* page
* edition

Date Fields
* Date Published (some formats have YEAR/MONTH sperately)
* Date Accessed (see [http://www.apastyle.org/elecsource.html here] for discussion from APA style guide.)

Again, I'll emphasize: "date published" is problematic. If one needs specificity, then better to have the following list of date classes: date (the generic), issued (braoder than published), copyright (often not the same as issuance date), accessed. -- bruce

Other fields
* Copyright/usage
* audience

* identifier (ISBN, ISSN, id, internal only, other)
* language (this can be handled by the xml:lang attribute native to HTML)

== Types and Roles ==
(Section is informative only as a place to capture various parts of publication citations.)

There are many different types of publications and this information should be captured in the citation. Possible types include:
* Novel/fiction (specify type -- literature, SF, romance, etc.?)
* Non-fiction
* Poem
* Play
* Magazine
* Reference (separate out encyclopedia, dictionary, almanac, etc.?)
* Journal
* Article within a journal
* Chapter within a book
* Dissertation
* Web Site
* Page within a web site
* Music Recording
* Music Score
* Video Recording
* Interview
* Physical object (Statue, Painting, etc.)
* ??

Question:
Certain works have specific types of citations, for example, the Bible--and, I assume, other religious works--have very specific citation formats with different relevant information (chapter/verse) than others, as do the works of Shakespeare. Should these be considered separate types/roles?

A: I think in terms of types, we should at least note the items (chapter, verse, etc). How they get dealt with is still way up in the air. - [[User:Tim White|Tim White]]

Likewise, there are several different roles associated with publications -- author, co-author, editor, translator, etc. Should these be captured under a master "role" or treated as individual elements?

A: Good question. I think there is an important distinction, but whether we follow a design pattern of "role-*" (or more likely "author-*) or some other pattern hasn't been discussed yet. - Tim

== Biblio RDF Class Schema ==
Regading the issue of types notes above, the [http://vocab.org/biblio/schema biblio schema] provides a comprehensive set of classes to describe citation metadata. It might prove useful as a guide for a micro-format. The primary classes are Agent, Reference, Collection, and Event. An "Article", then, would be a subclass of "Part", which in turn is a subclass of Reference. Likewise, a "Journal" is a subclass of a "Periodical," which in turn is a subclass of "Collection." An article would typically be linked to a journal through a dcterms:isPartOf relation.

== ISBN Uniform Resource Names ==

[http://www.faqs.org/rfcs/rfc3187.html RFC3187] defines an ISBN namespace for Uniform Resource Names (URNs).

Example:

URN:ISBN:0-395-36341-1

I'm not sure if any browser uses this data, but it might have an application in citations describing registered materials with an ISBN.

There is also a URN namespace for ISSN (International Standard Serial Number), which identifies serials/periodicals e.g. [http://alistapart.com A List Apart]. It is defined in [http://www.faqs.org/rfcs/rfc3044.html RFC3044]. Additional URN namespaces are listed at http://www.iana.org/assignments/urn-namespaces.

== You should know ==
* There are more then 1.300 citation ''styles'' in EndNote 9.
* Libraries have developed formats and rules for publications since more than 100 years. There are millions of records in library catalougues. You should '''at least''' be familiar with AACR and FRBR. There '''already are''' effords to create a new "microformat" called ''Resource Description and Access'' (RDA) [http://www.collectionscanada.ca/jsc/rdaprospectus.html]. Why don't you try to work with the professionals instead of amateurishly trying to reinvent the wheel and create yet another incompatible format? -- [[User:JakobVoss|JakobVoss]] 01:39, 5 Jun 2006 (PDT)
** I agree that the people involved in developing this microformat (including me) ought to be aware of these efforts (in particular FRBR), but I also think your argument is hopelessly naive and pretentious. The professionals you refer to are in fact library professionals, with their own bizarre traditios and unique information needs. Those are different than the professional scholars for whom citations are critical (me), or to the professional web developers who might want to implement these formats. What I do think is important is for us to understand the different design traditions, and their trade-offs, rather than to blindly create a microformat based on one of them -- Bruce (author of citeproc [http://xbiblio.sourceforge.net/citeproc] and csl [http://xbiblio.sourceforge.net/csl]).

Nice to meet you, Bruce! Maybe I'm naive but it still think that there is a way to combine the best of both worlds: scholars and library professionals. Both have developed bizarre traditions and it would be a pitty to create a new bizarre microformat that is not based on both of them. Thanks to your links to xbiblio. I a stumbled upon it a while ago but have to look at it deeper. -- [[User:JakobVoss|JakobVoss]] 11:48, 19 Jul 2006 (PDT)

=== ISBD ===

Oh, already a year ago! I was just trying to explain Microformats and its relevance for libraries ([http://jakoblog.de/2007/07/26/von-isbd-zum-web-20-mit-mikroformaten/ here (in German)]. You should have a look at the [http://en.wikipedia.org/wiki/International_Standard_Bibliographic_Description International Standard Bibliographic Description] (ISBD). These rules specify how a bibliographic should be displayed in a library catalouge. This format could be used as basis for hCitation because millions of records are availble in ISBD or variants in library catalouges all over the world.

Here is an example:

<pre>
Title: Harry Potter and the deathly hallows / Joanne K. Rowling. - [Children’s ed.], 1. ed. - London : Bloomsbury, 2007
ISBN: 0-7475-9105-9 - 978-0-7475-9105-4 (Children’s edition)
</pre>

This could be broken into "semantic peaces":

<pre>
<div class='hCitation'>
Titel:
Harry Potter and the deathly hallows /

Joanne K.
Rowling
</div>. -
[Children's ed.], 1. ed. -
London : Bloomsbury,
2007
</div>
<div>
ISBN:
0-7475-9105-9 -
978-0-7475-9105-4
(Children's edition)
</div>
</pre>

The advantage of ISBD is that it is very elaborated and covers many field and types of publications and sp*cial cases. Of course you need to simplifiy parts of it for the microformat. I'd prefer a bottom up design with the current mass of real-world records in todays libraries instead of top-down by thinking of an "ideal record" or limited playing databases. -- [[User:JakobVoss|JakobVoss]] 05:34, 26 Jul 2007 (PDT)

== OpenDocument ==
The OpenDocument Format also includes parts for citation and bibliography. See also the [http://bibliographic.openoffice.org/ OpenOffice Bibliographic project]. -- [[User:JakobVoss|JakobVoss]] 11:55, 19 Jul 2006 (PDT)
