Today two new record types were added to dx.doi.org resolution for Crossref DOIs. These allow anyone to retrieve DOI bibliographic metadata as formatted bibliographic entries. To perform the formatting we’re using the citation style language processor, citeproc-js which supports a shed load of citation styles and locales.

In fact, all the styles and locales found in the CSL repositories, including many common styles such as bibtex, apa, ieee, harvard, vancouver and chicago are supported. First off, if you’d like to try citation formatting without using content negotiation, there’s a simple web UI that allows input of a DOI, style and locale selection. If you’re more into accessing the web via your favorite programming language, have a look at these content negotiation curl examples. To make a request for the new “text/bibliography” record type: $ curl -LH “Accept: text/bibliography; style=bibtex” http://dx.doi.org.ezproxy.csu.edu.au/10.1038/nrd842 @article{Atkins_Gershell_2002, title={From the analyst’s couch: Selective anticancer drugs}, volume={1}, DOI={10.1038/nrd842}, number={7}, journal={Nature Reviews Drug Discovery}, author={Atkins, Joshua H. and Gershell, Leland J.}, year={2002}, month={Jul}, pages={491-492}} A locale can be specified with the “locale” record type parameter, like this: $ curl -LH “Accept: text/bibliography; style=mla; locale=fr-FR” http://dx.doi.org.ezproxy.csu.edu.au/10.1038/nrd842 Atkins, Joshua H., et Leland J. Gershell. « From the analyst’s couch: Selective anticancer drugs ». Nature Reviews Drug Discovery 1.7 (2002): 491-492. You may want to process metadata through CSL yourself. For this use case, there’s another new record type, “application/citeproc+json” that returns metadata in a citeproc-friendly JSON form: $ curl -LH “Accept: application/citeproc+json” http://dx.doi.org.ezproxy.csu.edu.au/10.1038/nrd842 {“volume”:“1”,“issue”:“7”,“DOI”:“10.1038/nrd842”,“title”:“From the analyst’s couch: Selective anticancer drugs”,“container-title”:“Nature Reviews Drug Discovery”,“issued”:{“date-parts”:[[2002,7]]},“author”:[{“family”:“Atkins”,“given”:“Joshua H.”},{“family”:“Gershell”,“given”:“Leland J.”}],“page”:“491-492”,“type”:“article-journal”} Finally, to retrieve lists of supported styles and locales, see:

Further to my previous post “NIH Mandate and PMCIDs” we’ve been looking into linking to articles on publishers’ sites from PubMed Central (PMC). There are a couple of ways this happens currently (see details below) but these are complicated and will lead to broken links and more difficulty for PMC and publishers in managing the links. Crossref is going to be putting together a briefing note for its members on this soon.

The main issue we are raising with PMC, and that we will encourage publishers to raise too, is why doesn’t PMC just automatically link DOIs? Most of the articles in PMC have DOIs so this would require very little effort from PMC and no effort from publishers and would give readers a perisistent link to the publisher’s version of an article.

A couple weeks back there was a meeting of the Open Archive Initiative‘s Object Reuse and Exchange (OAI-ORE) Technical Committee hosted in the Butler Library at Columbia University, New York.

Lorcan Dempsey of OCLC blogs here on the report (PDF format) that was generated from that meeting. As does Pete Johnston of Eduserv here.
