Citation Examples
The following examples are real world examples of citations found on the web. Please add to this list. The idea is that we get a solid sample of examples and see what commonalities there are amonst them and try to build this microformat so that it can meet 80% of typical uses.

Important
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]
These issues pertain mainly to Errata, Comments and Authors Reply and Article Retractions.
- 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- the published withdrawal letter (which explains why the article was retracted)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
- IMPORTANT: electronic publishing ahead of print (EPUB)
- 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?

CiteProc XHTML Output
The XHTML output for CiteProc[2] wasn't designed per se as a microformat, but is probably not a bad place to start. It is desgined to handle a wide range of content. Here is the APA output:

- volume
- issue

- issue
- container (a book serves as container for a chapter)

Wikipedia
Wikipedia makes extensive use of bibliographic citations, in particular to point readers to further information sources. There are differing formats depending on Wikipedia's language:
English Wikipdia
The kinds of citations used on the site run the full gamut. Here are breakdowns of four categories previously mentioned:
Book
- title
- author
- publisher
- year
- ISBN
- url (indirectly via special wikipedia ISBN page)
Journal Articles
- author (truncated list)
- year
- title
- journal title
- journal number
- page range
- DOI
Court cases
- title
- case number
- note that legal standards for referring to cases include some inscrutable abbreviations that are probably more detailed than just "case number"
- court name
- year
- description/abstract
U.S. Law
- title (title number, for example "50" in "50 U.S.C. chapter 36."
- chapter title (name, for example "Foreign Intelligence Surveillance" )
- chapter number
- section, paragraph, subparagraph numbers (optionally)
Conference presentations
- title
- location
- date
- author (implied - the page is about this person)

EPrints.org
Based on Expressing Dublin Core in HTML/XHTML meta and link elements and rfc2731, Eprints.org uses the following Dublin Core terms in meta tags in the HTML HEAD of each paper's page:
- title
- creator (author)
- description (abstract)
- date
- type
- identifier (a url)
- format
- a strange syntax for the meta content:"pdf http://eprints.ecs.soton.ac.uk/12070/01/Alani-final.pdf"" for the format term...
- fulltext
- this is in a rel-alternate link element. The class is 'fulltext', and the href is the same link as in format, only a valid URL this time.
In the body of the page, they use the following classes, now no longer DC terms:
- title
- authors (a flat list with abbreviated names)
- year
- conference
- conference location
Self-Citation Example
One example of an article that includes a statement "please cite as" (a self-description):

Analysis of Examples
With exception of just a few properties, all of the above appeared in atleast two different examples. The following properties were very common in most the example formats:
- title
- subtitle
- author
- publication date
- description
- pages
- ISBN
- publisher
Styles
This does NOT define a format, but instead shows how the format should be displayed. This is something out of the direct scope of this project. CSS styles will handle the look-and-feel of the text, and the author can put it in any order they choose. These links are mentioned for two reasons, one is informative, the other is so we know at least meet the minimum properties that are used in the styles.
- MLA Style
- Chicago, MLA, and APA styles
- Writer's Workshop citation style page (detailed citation style info)
- Blue Book for legal citations
- Columbia University Citation Style developed for modern internet citations
