The Names Project

Was reminded to blog about this after reading Lorcan’s post on the Names Project being run by JISC. From the blurb: _“The project is going to scope the requirements of UK institutional and subject repositories for a service that will reliably and uniquely identify names of individuals and institutions.   It will then go on to develop a prototype service which will test the various processes involved. This will include determining the data format, setting up an appropriate database, mapping data from different sources, populating the database with records and testing the use of the data.

InChIKey

In IdentifiersInchi

The InChI (International Chemical Identifier from IUPAC) has been blogged earlier here. RSC have especially taken this on board in their Project Prospect and now routinely syndicate InChI identifiers in their RSS feeds as blogged here. As reported variously last month (see here for one such review) IUPAC have now released a new (1.02beta) version of their software which allows hashed versions (fixed length 25-character) of the InChI, so-called InChIKey’s, to be generated which are much more search engine friendly.

Oh No, Not You Again!

In Identifiers

Oh dear. Yesterday’s post “Using ISO URNs” was way off the mark. I don’t know. I thought that walk after lunch had cleared my mind. But apparently not. I guess I was fixing on eyeballing the result in RDF/N3 rather than the logic to arrive at that result.

Using ISO URNs

In Identifiers

(Update - 2007.10.02: Just realized that there were some serious flaws in the post below regarding publication and form of namespace URIs which I’ve now addressed in a subsequent post here.)

By way of experimenting with a use case for ISO URNs, below is a listing of the document metadata for an arbitrary PDF. (You can judge for yourselves whether the metadata disclosed here is sufficient to describe the document.) Here, the metadata is taken from the information dictionary and from the document metadata stream (XMP packet).

The metadata is expressed in RDF/N3. That may not be a surprise for the XMP packet which is serialized in RDF/XML, as it’s just a hop, skip and a jump to render it as RDF/N3 with properties taken from schema whose namespaces are identified by URI. What may be more unusual is to see the document information dictionary metadata (the “normal” metadata in a PDF) rendered as RDF/N3 since the information dictionary is not nodelled on RDF, not expressed in XML, and not namespaced. Here, in addition to the trusty HTTP URI scheme, I’ve made use of two particular URI schemes: “iso:” URN namespaces, and “data:” URIs.

Whole Lotta ID

In Identifiers

ISO has registered with the IANA a URN namespace identifier (“iso:”) for ISO persistent resources. From the Internet-Draft: “This URN NID is intended for use for the identification of persistent resources published by the ISO standards body (including documents, document metadata, extracted resources such as standard schemata and standard value sets, and other resources).” The toplevel grammar rules (ABNF) give some indication of scope: NSS = std-nss std-nss = "

Authors in Context?

On the subject of author IDs (a subject Crossref is interested in and on which held a meeting earlier this year, as blogged about here), this post by Karen Coyle “Name authority control, aka name identification” may be worth a read. She starts off with this: “Libraries do something they call “name authority control”. For most people in IT, this would be called “assigning unique identifiers to names.” Identifying authors is considered one of the essential aspects of library cataloging, and it isn’t done in any other bibliographic environment, as far as I know.

XMP-Ville

In Xmp

Been so busy looking into the technical details of XMP that I almost forgot to check out the current landcsape. Luckily I chanced on these articles by Ron Roszkiewicz for The Seybold Report (and apologies for lifting the title of this post from his last). The articles about XMP are well worth reading and chart the painful progress made to date:

The Name’s The Thing

In Xmp

I’m always curious about names and where they come from and what they mean. Hence, my interest was aroused with the constant references to “XAP” in XMP. As the XMP Specifcation (Sept. 2005) says:

“NOTE: The string “XAP” or “xap” appears in some namespaces, keywords, and related names in this document and in stored XMP data. It reflects an early internal code name for XMP; the names have been preserved for compatibility purposes.”

Actually, it occurs in most of the core namespaces: XAP, rather than XMP.

ACAP - Any chance of success?

In Search

ACAP has released some documents outlining the use cases they will be testing and some proposed changes to the Robots Exclusion Protocol (REP) - both robots.txt and META tags. There are some very practical proposals here to improve search engine indexing. However, the only search engine publicly participating in the project is http://www.exalead.com/ (which according to Alexa attracted 0.0043% of global internet visits over the last three months). The main docs are “ACAP pilot Summary use cases being tested”, “ACAP Technical Framework - Robots Exclusion Protocol - strawman proposals Part 1”, “ACAP Technical Framework - Robots Exclusion Protocol - strawman proposals Part 2”, “ACAP Technical Framework - Usage Definitions - draft for pilot testing”.

Style Guides Recommend DOI strings

In Citation Formats

A couple of recent posts - from A couple of recent posts - from at Jefferson University and IFST at Univ of Delaware- note that the AMA and APA style guides now recommend using a DOI, if one is assigned, in a journal article citation.

A citation in the APA style with a DOI would be:

Conley, D., Pfeiffera, K. M., & Velez, M. (2007). Explaining sibling differences in achievement and behavioral outcomes: The importance of within- and between-family factors. Social Science Research36(3), 1087-1104. doi:10.1016/j.ssresearch.2006.09.002

In the AMA style a reference would be:

Kitajima TS, Kawashima SA, Watanabe Y. The conserved kinetochore protein shugoshin protects centromeric cohesion during meiosis. Nature. 2004;427(6974):510-517. doi:10.1038/nature02312

This is great news. I haven’t looked at the full style guides but it’s not clear if information is given about linking DOIs via http://dx.doi.org/
