Hi Andy and all, first, welcome as new reader on this list. By the way, I'm currently planning how we will get Named Graphs and = SPARQL into the next RAP release and maybe you would comment on how our plans = fit with the DAWG and the Jena timeline. 1. Daniel Westphal will port NG4J to PHP and starting now and hopes to = be done mid May (including the API, TriX and a DB backend).=20 Q:Does Jena already have concrete plans on how to support Named Graphs? Maybe we could implement the same API. 2. Another Student (Ralf Jacob) will implement SPARQL protocol into our Joseki clone and might also implement a client library (remoteModel) and some access control mechanisms (graph, resource and predicate level). He will start 1st of June and might be done at the end of June. Q: Will the SPARQL protocol be stable enough by then for being = implemented? Q: Do you know of any other work on access control for RDF servers? 3. Alberto wrote a SPARQL query language parser for PHP.=20 http://gargonza.asemantics.org/downloads/sparql.php http://demo2.asemantics.com/rdf4food/sparql.html I'm still looking for somebody to update this parser for the new SPARQL syntax and write the actual query engine. I currently have nobody for = this. So it would be really cool if somebody from this list would volunteer. Q: Any guess on the timeline when the spec will be stable? 4. There are also two people (Hannes Gassert and Tae IL Erdmann) working = on an RDF browser implemented using RAP and Fresnel (http://simile.mit.edu/repository/fresnel/trunk/docs/manual/FresnelVocabu= lar y.htm) which might also become part of the next RAP release.=20 Q to Hannes Gassert: Right or do you want to distribute Arago as a = separate download?
