[tdwg-guid] First step in implementing LSIDs

SPARQL will handle URIs that aren't HTTP URIs. For example, I can
perform SPARQL queries on uBio RDF that has some namespaces and
resources identified by LSIDs.
By Semantic web tools I'm thinking more generally, such as data
browsers and triple stores, that is, anything that reads RDF and
expects to be able to follow any resource in the RDF. If those
resources aren't HTTP URIs then these tools won't know how to fetch
One case where SPARQL does need HTTRP URIs is the "FROM" statement,
where it can fetch data from the web as part of the query.
