[Treebase-devel] Searching metadata through OAI-PMH?

[Carl B. <cbo...@gm...>]

Hi,

I'm wondering what is the recommended way to query for TreeBASE entries
matching certain metadata (i.e. author) is, using the the OAI-PMH interface
the way one can already do with the phylo-ws interface.  I'm looking at the
specification for the
OAI-PMH<http://www.openarchives.org/OAI/openarchivesprotocol.html#ListIdentifiers>verb
ListIdentifers, and it seems I can only specify dates using from or
until, but not query by other metadata.  It seems I can change the type of
metadata format (oai_dc vs mets, though the wiki recommends oai_dc) and this
date range.

I can simply download all the metadata and search it locally, (as I do in my
current implementation for the TreeBASE R
package<http://www.carlboettiger.info/archives/1702>),
but I was wondering if there's a better way to handle this?  (Of course this
would be more of a concern if the metadata were millions of files rather
than a few thousand, but I'd also like my OAI-PMH methods to be consistent &
intelligent enough to be applied to other databases such as Dryad, etc)

Any update on getting Dryad identifiers into TreeBASE entries?


Thanks much for your advice!
Carl
