This is probably much like Ricardo's LSID proxy proposal. Except in my opinion it should be extended further to be a general GUID resolver to help resolve whatever form is used for GUIDs - then one could embed a handle, LSID, HTTP URI, FTP URI, LDAP URI, or even, for the ancients of the internet, z39.50 URIs in a resolver proxy URL and get something back. The problem of course is that the content that comes back will be different for different protocols - but it would, I suspect be possible to provide a generic form of metadata for the different protocols.</DIV></BLOCKQUOTE><DIV><BR class="khtml-block-placeholder"></DIV>This is pretty much what <A href="http://bioguid.info">http://bioguid.info</A> does with respect to DOIs, Handles, PubMed identifiers, and (some) specimens.

This part stalled due to my trying to extract whatever I could from GenBank records, such as specimen links and DOIs if there is no PubMed record (see <A href="http://bioguid.blogspot.com/2007/04/adding-guids-to-genbank-records.html">http://bioguid.blogspot.com/2007/04/adding-guids-to-genbank-records.html</A> for details).
