Part of the overall effort to develop a citation microformat.
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:
- 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.
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:
- a reading list for a seminar
- The publication list for a conference (e.g., subscribe to SIGGRAPH and see the updated conference proceedings every year)
- the issues of a journal
- a particular research group or researcher's publications
- Not just research: a popular author's publications (e.g., Malcolm Gladwell's Archive)
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 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.
Cite a journal on Wikipedia
- (from a mailing list):
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
- Zotero, a Firefox extension to help collect, manage, and cite research sources.
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:
- microformats design principles
- Semantic HTML Design Principles
- use as precise as HTML semantics as are available
Semantic HTML Design Principles
- Reuse the schema (names, objects, properties, values, types, hierarchies, constraints) as much as possible from pre-existing, established, well-supported microformats.
- 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.
- For types with multiple components, use nested elements with class names equivalent to the names of the components.
- Plural components are made singular, and thus multiple nested elements are used to represent multiple text values that are comma-delimited.
- Use the most accurately precise semantic HTML building block for each object etc.
- Otherwise use a generic structural element (e.g.
<div>), or the appropriate contextual element (e.g. an
- 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.
- 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?)
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 citation properties
In rough order of presentation and relevance/frequency:
dt-published- reused from uf2 h-entry
p-author- same, with optional substructured h-card
p-name- common property instead of entry-title
u-url- a URL to access the cited work
u-uid- a URL/URI that uniquely/canonically identifies the cited work, canonical permalink.
p-publication- 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.
dt-accessed- 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.
p-contentfor when the citation includes the content itself, like when citing short text notes (e.g. tweets).
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:
- 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 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.
web citation property details
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:
- for each property, what equivalent TCMOS, APA, MLA terms/vocabulary is being expressed/captured as researched in the 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.
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>
- 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.
web citation examples in the wild
Real world in the wild examples:
- ... add uses of h-cite you see in the wild here.
Real but not quite wild (use by the brainstorm author)
- Every blog post on http://tantek.com has a text field for copying h-cite markup for that blog post.
- Why you should say HTML classes, CSS class selectors, or CSS pseudo-classes, but not CSS classes 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.
- Test #IndieWeb : Parvenir à « POSSEr » un article vers Twitter has an h-cite of a short note:
<blockquote><p> <cite class="h-cite"> <a class="u-url p-name" href="http://tantek.com/2013/104/t2/urls-readable-speakable-listenable-retypable"> URLs should be readable, speakable, listenable, and unambiguously retypable, e.g. from print: tantek.com/w/ShortURLPrintExample #UX </a> (<abbr class="p-author h-card" title="Tantek Çelik">Çelik</abbr> <time class="dt-published">2013-04-14</time>) </cite> </p></blockquote>
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:
- IndieWebCamp2012: Academic Citations for the Web
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.)

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.
- 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.
- Perhaps class="hcite" with
<cite>recommended as the root element. E.g.
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 Edward 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
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.
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)
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.
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:
- Avoid re-keying references
- Adapt to new journal styles by changing CSS
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.
Examples in the wild
Pages which start to use the discussion above to create working examples in using hcite: (This section could be used as a base for a page like "hcite-examples-in-wild" later).
Please add new examples to the top of this section.
- Example User Page at the regional computer lab Erlangen, Germany, based on the universal information system UnivIS marked up with vcard, hcalender (optional, if user makes a lecture) and hcite.
