I think most of that went over my head for the moment.

Thanks, that's excellent, sorry I didn't realize what it was before.

That just worked fine for me given the dryad short from identifier to the
data.  I'm curious what the flow would look like from a Dryad identifier to
a study, i.e. if that would go through METS or OAI-PMH to get the
identifiers for each data file.  i.e. If I followed the discussion earlier,
treeBASE would be able to provide the short form dryad identifer to the
study.  It looks like I could enter that into METS as outlined in (2) on the
wiki, extract the identifiers to the data, enter each those into METS, and
proceed as on the wiki to get the files?

I see I can check the MIMETYPE once I'm on the METS page for a datafile.  I
don't suppose I can query by MIMETYPE?

Thanks for the help, just started learning my way around the api.
