This means we need Princeton to do a redirect, right? This may be
possible but we have to check with them.

I would like to continue working on (a) with hash URIs as it is now,
while we discuss solutions on (b). So the next RDF version and draft
Note might not reflect these discussions yet, although of course I
will try to be as up-to-date as possible. Also, if it is not possible
to let Princeton to do redirects it seems sensible to stick with the
files-with-hash-URIs solution for both (a) and (b).
I discussed with Peter Mika and Michel Klein about a solution to (b):
- we use slash URIs in the Princeton space, e.g.
http://wordnet.princeton.edu/rdf/entity
- Princeton server redirects this with 303 to another namespace which
has the version number of the latest version, e.g.
- http://wordnet.princeton.edu/rdf20/entity
- Princeton redirects this with 303 to another namespace where we host
the actual RDF files. THis can e.g. be a server at my university (VU
Amsterdam)
- there a dynamic script queries the current RDF files for all
subjects that have the requested URI in a triple which are then returned.
Advantages:
- compliant with httpRange-14
- GETting one URI does not return whole WN-RDF file
Problems/Issues:
- requires Princeton to do redirect
- three redirects for one lookup
- requires dynamic script and hosting other than Princeton
- we should agree on which triples should be returned (proposal is
only triples with that URI as subject, other possibilities exist)
- this is not best practice we're implementing
