Aside:

Just checked these out - it would be better to use Commons Logging
rather than hardwire log4j because sparq4j is a library that has to
co-exist with other subsystems.

Using org.apache.logging is just as easy.  It uses Log4J if it can find
an implementation on the classpath else uses Java logging else uses a
simple built in logger.

Will do.

What data and implementations are we going to test against?  It would be
useful to be able for us all to be able to recreate the same tests.

I have a small server at http://sparql.org/sparql which is backed by
Joseki and ARQ.  See http://sparql.org/query.html  Just don't overload
it by loading large graphs (it should give an error if the graph is over
10K triples).

What's the state of Profium's engine?  I'd like to try my client library
in parallel to compare SPARQl4j with it.  It's in the ARQ codebase - and
the command line arq.sparql will access remote services with the
--service argument (over HTTP).

Good way forward.
