Here are some of my ideas:

1. Greg has a subclass of RDF::Trine::Model that does forward-chaining
RDFS reasoning. It would be nice if we could get this stable-ish.
Possibly split it into a generic rules-based reasoning model, and a
separate module that provides a set of RDFS rules. We could even build
some other rules-providing modules, such as vocab-specific ones (e.g. a
set of rules for FOAF would be able to generate foaf:mbox_sha1sum
properties from foaf:mbox data).

2. I'd like to build an ACL-protected subclass of RDF::Trine::Store.
Data would be protected at a per-graph level (rather than a per-triple
level). I've already got RDF::ACL working, but need help to get the
get_statements, add_statement, etc methods of RDF::Trine::Store to
respect an ACL.

3. Given #2, I'd like to build a SPARQL protocol endpoint that uses FOAF
+SSL to establish the client's identity, and limit service to them
depending on an ACL.
