JOPA 0.9.10 Release

New version of JOPA has just been released. It brings partial implementation of an important feature - SPARQL result set mapping.

At this moment, the mapping supports variable and constructor results. Constructor results are certainly more useful, since they allow one to map variable bindings from the result set to constructor parameters, so that data can be loaded from repository without using the usual entity lifecycle.

Entity results mapping is planned for the next release.
