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.
Citation styles, though perhaps present in proxy through aggregate real world [[citation-examples]], are also good source of explicit citation schemas, and thus implicit formats.

** name (username), note text, datetime, "Tweet". In more detail: author’s real name (user name if known and different), entire text of the tweet in quotation marks without changing the capitalization, date and time of the message and the medium of publication "Tweet". If only the user name is known, give it alone. e.g. <blockquote style="padding-left:2em; padding-right:2em; text-indent:-2em"><nowiki>Athar, Sohaib (ReallyVirtual). “Helicopter hovering above Abbottabad at 1AM (is a rare event).” 1 May 2011, 3:58 p.m. Tweet.</nowiki></blockquote> <blockquote>"The date and time of a message on Twitter reflect the reader’s time zone. Readers in different time zones see different times and, possibly, dates on the same tweet. The date and time that were in effect for the writer of the tweet when it was transmitted are normally not known."</blockquote>
** MLA is incorrect about "normally not known". The date and time of tweet creation *are* known and are in the markup in ISOdate form. Thus we should presume they would choose to use that information rather than that of the reader's time zone (which makes no sense, reader of the tweet? reader of the citation of the tweet? unpredictable). - [[User:Tantek|Tantek]] 20:23, 8 May 2012 (UTC)

The sub-sections probably needs sorting (alphabetical?) to make it easier to browse since it is quite large.[[User:Tantek|Tantek]] 19:26, 2 April 2009 (UTC)
 
=== 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 DEFINIATIVE, any errors should be corrected. More formats will be added to the list as they are mapped.

=== 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.

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].


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 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.

=== 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.
=== 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:
  <span class='title'>Harry Potter and the deathly hallows</span> /
  <span class='n'>
    </span><span class='given-name'>Joanne K.</span>
    <span class='family-name'>Rowling</span>
  </div>. -
  [<span class='edition'>Children's ed.</span>], <span class='edition-number'>1.</span> ed. -
  <span class='location'>London</span> : <span class='publisher-name'>Bloomsbury</span>,
  <span class='publication-year'>2007</span>
</div>
<div>
  ISBN:
  <span class='ISBN'>0-7475-9105-9</span> -
  <span class='ISBN'>978-0-7475-9105-4</span>
  (<span class='edition'>Children's edition</span>)
</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)

=== Structurally-Based Citation Formatting ===
Bruce D’Arcus has drafted a partial proposal with a few examples, and a schema for the parts of a citation:
http://www.users.muohio.edu/darcusb/misc/citations-spec.html
* container
* part numbers
* creator
* title
* publisher
* origin place
* year
* genre
* volume
* number
* date
* location
* medium
== additional sources for citation formats ==
* There are more then 1300 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)
== common properties across formats ==
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
== Concerns not addressed by existing formats ==
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?

Latest revision as of 16:21, 18 July 2020


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.

styles

Citation styles, though perhaps present in proxy through aggregate real world citation-examples, are also good source of explicit citation schemas, and thus implicit formats.

Subsections from Wikipedia: Citation Styles and focus on documenting citation styles to online resources first per the principle of solving a simpler problem first.

MLA

MLA note permalink

  • MLA Style FAQ: How do I cite a tweet?
    • name (username), note text, datetime, "Tweet". In more detail: author’s real name (user name if known and different), entire text of the tweet in quotation marks without changing the capitalization, date and time of the message and the medium of publication "Tweet". If only the user name is known, give it alone. e.g.

      Athar, Sohaib (ReallyVirtual). “Helicopter hovering above Abbottabad at 1AM (is a rare event).” 1 May 2011, 3:58 p.m. Tweet.

      "The date and time of a message on Twitter reflect the reader’s time zone. Readers in different time zones see different times and, possibly, dates on the same tweet. The date and time that were in effect for the writer of the tweet when it was transmitted are normally not known."

    • MLA is incorrect about "normally not known". The date and time of tweet creation *are* known and are in the markup in ISOdate form. Thus we should presume they would choose to use that information rather than that of the reader's time zone (which makes no sense, reader of the tweet? reader of the citation of the tweet? unpredictable). - Tantek 20:23, 8 May 2012 (UTC)

The sub-sections probably needs sorting (alphabetical?) to make it easier to browse since it is quite large.Tantek 19:26, 2 April 2009 (UTC)

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

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

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/

(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

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:

sourceThe 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-titleTitle of the article
volumeVolume of the journal
issueIssue of the journal
fpagePage number on which the article starts
nameName of an author or editor
yearYear of publication
monthMonth of publication (if present)
dayDate 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."

Bib-enabled Applications

Reference-management applications that support the bib format. This is an incomplete list.

Desktop Applications
  • EndNote (Large market share) (but not really BiBTeX oriented, importation macros are old and you must first use Jabref and export to Endnote formats)
  • BibDesk
  • BibDB
  • Bib-it
  • Jabref Probably the most useful application because of its facility to search Pubmed (and also to export in many other formats).
  • Large list of other apps at dmoz and Wikipedia
Web Applications
Academic Databases

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:

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&amp;rft_val_fmt=info:ofi/fmt:kev:mtx:book&amp;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.

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 Uniform Resource Names

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. A List Apart. It is defined in RFC3044. Additional URN namespaces are listed at http://www.iana.org/assignments/urn-namespaces.

ISBD

Oh, already a year ago! I was just trying to explain Microformats and its relevance for libraries (here (in German). You should have a look at the 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:

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)

This could be broken into "semantic peaces":

<div class='hCitation'>
  Titel:
  <span class='title'>Harry Potter and the deathly hallows</span> /
  <span class='n'>
    </span><span class='given-name'>Joanne K.</span>
    <span class='family-name'>Rowling</span>
  </div>. -
  [<span class='edition'>Children's ed.</span>], <span class='edition-number'>1.</span> ed. -
  <span class='location'>London</span> : <span class='publisher-name'>Bloomsbury</span>,
  <span class='publication-year'>2007</span>
</div>
<div>
  ISBN:
  <span class='ISBN'>0-7475-9105-9</span> -
  <span class='ISBN'>978-0-7475-9105-4</span>
  (<span class='edition'>Children's edition</span>)
</div>

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. -- JakobVoss 05:34, 26 Jul 2007 (PDT)

OpenDocument

The OpenDocument Format also includes parts for citation and bibliography. See also the OpenOffice Bibliographic project. -- JakobVoss 11:55, 19 Jul 2006 (PDT)

Wikimedia foundation projects

Structurally-Based Citation Formatting

Bruce D’Arcus has drafted a partial proposal with a few examples, and a schema for the parts of a citation:

http://www.users.muohio.edu/darcusb/misc/citations-spec.html

  • container
  • part numbers
  • creator
  • title
  • publisher
  • origin place
  • year
  • genre
  • volume
  • number
  • date
  • location
  • medium

additional sources for citation formats

  • There are more then 1300 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) [1]. Why don't you try to work with the professionals instead of amateurishly trying to reinvent the wheel and create yet another incompatible format? -- 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 [2] and csl [3]).

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. -- JakobVoss 11:48, 19 Jul 2006 (PDT)

common properties across formats

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 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. - 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


Concerns not addressed by existing formats

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?
