Talked with Chris Lynnes a bit about URI identifiers for the
entities needed for the ToolMatch semantic service the ESIP
semantic web cluster is working on.
I want to tie it in with the GCIS identifiers we've been
talking about, and proposed we come up with a common URI
scheme which we can root under globalchange.gov.
More discussion about these URIs will continue 'over there'..

Consensus was that we would like to shoot for URIs with RDF content. No
objections to going with GCIS naming, so...let's go with it.
I would suggest that we start off with minimal properties, but one (or
more) property we should have is a pointer to somewhere where more
information can be gotten. For this, I suggest gcmdDif, doi and
datasetUrl (for dataset landing pages).
Eventually, content negotiation to fetch in RDF/XML vs. HTML would be nice.
Next question is whether service access points (WMS, WCS, OPeNDAP,
THREDDS) should also be a property within the GCIS-hosted content. What
do you think?
If you think no, we can always host the access point triples somewhere
else. We need it to try inferring which tools work with a given dataset.
As for the identifier naming scheme, my suggestion is to allow for three:
http://globalchange.gov/dataset/gcmd/<dif_entry_id>
http://globalchange.gov/dataset/doi/<doi>
http://globalchange.gov/dataset/uuid/<uuid>
The dif_entry_id can account for nearly all NASA datasets, and a lot
more besides. The doi can account for DOE and possibly others, and the
uuid can be minted by anyone that does not fall into those categories.
