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 microformats, then its 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 extention 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 DEFINIATIVE, any errors should be corrected. More formats will be added to the list as they are mapped.

Dublin Core Metadata
Dublin Core metadata uses a small vocabulary to descibe the data.
- contributor
- coverage
- creator
- date
- description
- format
- identifier
- language
- publisher
- relation
- rights
- source
- subject
- title
- type
From those there are specialised types where are just refinments of the previous, for example:
- abstract refines description.
- accessRights refines rights
Guidelines for Encoding Bibliographic Citation Information in Dublin Core Metadata
MODS (Metadata Object Description Schema)
This is a format developed for the Libray 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/
(the schema is very big, once i devote the proper time to review it, i will post more about the structure -brian)
NLM Journal Publishing DTD
http://dtd.nlm.nih.gov/publishing/tag-library/2.1/n-fv30.html
The NLM Journal Publishing DTD defines the schema used for publishing journal articles as XML. The
<citation>
element can be placed with paragraphs or within a
<ref-list>
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:
| source | 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.) |
| article-title | Title of the article |
| volume | Volume of the journal |
| issue | Issue of the journal |
| fpage | Page number on which the article starts |
| name | Name of an author or editor |
| year | Year of publication |
| month | Month of publication (if present) |
| day | Date of publication (if present) |
The other elements (described here) may be tagged if desired. Use the <source> element for titles of books, conference proceedings, etc."

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
In particular, see the list of different reference types.
A sample item in RIS format:
TY - JOUR A1 - Baldwin,S.A. A1 - Fugaccia,I. A1 - Brown,D.R. A1 - Brown,L.V. A1 - Scheff,S.W. T1 - Blood-brain barrier breach following cortical contusion in the rat JO - J.Neurosurg.

OpenURL
OpenURL aka 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 SFX. The Context Object in Span (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):
<p><b>ISBN</b>: <span class='Z3988' title='ctx_ver=Z39.88-2004&rft_val_fmt=info:ofi/fmt:kev:mtx:book&rft.isbn=0679426612'> 0679426612</span></p>
Another example, a journal this time:
<span class="Z3988" title="ctx_ver=Z39.88-2004&rft_val_fmt=info:ofi/fmt:kev:mtx:journal&rft.issn=1045-4438"></span>
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 types of citations: book, dissertation, journal, patent. It would be possible to simply provide a standard XHTML bundling for these keys as a microformat.
Example
<div class="openurl-journal"> <span class="aulast">Berners-Lee</span>, <span class="aufirst">Tim</a>; Hendler, James; Lassila, Ora.</span> "<span class="atitle">The Semantic Web</span>". <span class="jtitle">Scientific American</span> <span class="volume">284</span>(<span class="issue">5</span>), pp. pp. <span class="pages">34-43</span>. <span class="issn">0036-8733</span> </div>
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 have been noted 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 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: 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.

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

Date Fields
- Date Published (some formats have YEAR/MONTH sperately)
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
- 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. - 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 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:// Protocol
RFC3187 defines an isbn protocol
Example:
I'm not sure if any browser uses this data, but it might be have an application in citations describing registered materials with an ISBN
