Elsevier have released this video about the challenge, featuring a few of the contestants. I couldn't get my act together in time to send anything useful, and having seen the 16 gigabytes song (full version here), I'm glad I didn't -- there's just no way I could compete with Michael Greenacre and Trevor Hastie.

One of the judges for the Elsevier Article 2.0 Contest is Andrew Perry, whose blog has some posts on Noel O'Boyle's OpenRef idea (see DOI or DOH? Proposal for a RESTful unique identifier for papers). Andrew discusses some implementations he has come up with, and compares OpenRef with OpenURL. This prompted me to add OpenRef-style identifiers to bioGUID's OpenURL resolver.

Chris Freeland's tweet alterted me to the Elsevier Article 2.0 Contest: Elsevier are clearly looking for ideas (they also have their Grand Challenge), and there's been some interesting commentary on the Article 2.0 contest.

One problem with my cunning plan to use Mediawiki REDIRECTs to handle DOIs is that some DOIs, such as those that BioOne serves based on SICIs contain square brackets, [ ], which conflicts with wiki syntax.

Bibliographic coupling is a term coined by Kessler (doi:10.1002/asi.5090140103) in 1963 as a measure of similarity between documents. If two documents, A and B, cite a third, C, then A and B are coupled. I'm interested in extending this to data, such as DNA sequences and specimens. In part this is because within the challenge dataset I'm finding cases where authors cite data, but not the paper publishing the data.

Duncan Hull alerted me to his paper "Defrosting the Digital Library: Bibliographic Tools for the Next Generation Web" ( PloS Computational Biology , doi:10.1371/journal.pcbi.1000204). Here's the abstract: It's an interesting read, and it also cites my bioGUID project.

Following on from adding specimens to my OpenURL resolver, I've added support for GenBank records. Either an OpenURL request such as http://bioguid.info/openurl?id=genbank:DQ502033, or the short URL http://bioguid.info/genbank/DQ502033 will resolve the GenBank record for accession number DQ502033.

Thinking more and more about using Mediawiki (or, more precisely, Semantic Mediawiki) as a platform for storing and querying information, rather than write my own tools completely from scratch. This means I need ways of modelling some relationships between identifiers and objects. The first is the relationship between document identifiers such as DOIs and metadata about the document itself.

Following on from the previous post, I wrote a simpe Mediawiki extension to insert a Google Book into a wiki page. Written in a few minutes, not tested much, etc. To use this, copy the code below and save in a file googlebook.php in the extensions directory of your Mediawiki installation.
