When I created an experimental version of the Perl client RDF::AllegroGraph::Easy it worked against the AG server 3.1.1.

Since then some subtle changes occurred, so that I have upgraded the client to continue to work.

Franz Inc. has also provided me with a pre-release of AG 4. It is a very different machine and my first impression is that the Perl client will most likely break.

I'll try to find a time window during which I can work on a compatible version. No promises.
