Andrei,

I would be interested. I have worked on ACL a lot recently, with a
goal to produce a transparent JAX-RS authorization filter for our
Graphity platform: http://graphity.org.

I have successfully implemented the filter using W3C ACL ontology and
plain SPARQL 1.1, but the code is unfortunately closed-source so far.
Single SPARQL query checks access for a specific foaf:Agent instance
(or foaf:Agent class in case of public access) and uses federation if
necessary. The main issues I've encountered were mostly related to
distributing ACL data across repositories and/or named graphs and
attaching them to user accounts.
