OpenHandle: Languages Support

Following up the earlier post on OpenHandle, there are now a number of language examples which have been contributed to the project. The diagram below shows the OpenHandle service in schematic with various languages support. Briefly, OpenHandle aims to provide a web services interface to the Handle System to simplify access to the data stored for a given Handle.
(Note that the diagram is an HTML imagemap and all elements are “clickable”.)

NIH Mandate and PMCIDs

The NIH Public Access Policy says “When citing their NIH-funded articles in NIH applications, proposals or progress reports, authors must include the PubMed Central reference number for each article” and the FAQ provides some examples of this:
Examples:
Varmus H, Klausner R, Zerhouni E, Acharya T, Daar A, Singer P. 2003. PUBLIC HEALTH: Grand Challenges in Global Health. Science 302(5644): 398-399. PMCID: 243493
Zerhouni, EA. (2003) A New Vision for the National Institutes of Health. Journal of Biomedicine and Biotechnology (3), 159-160. PMCID: 400215
It’s interesting to note that on PMC itself both the PMCID and DOI are included – but the DOI isn’t linked. Two things occur to me – 1) should CrossRef map DOIs to PMCIDs and vice versa and make PMCIDs available in it’s query interfaces and 2) shouldn’t publishers ask that the PMC copy of the article link back to the publisher version? It would be very easy with the DOI.
