[ann] New versions of D2RQ and D2R Server released

All,

We have released D2RQ v0.5.1 and D2R Server v0.4.

The D2RQ engine is a system for mapping relational databases to RDF.  
D2R Server is a SPARQL and Linked Data server that allows access to  
the data stored in D2RQ-mapped databases.

The major new feature in this release: D2R Server can now be deployed  
as a J2EE web application inside an existing servlet container such as  
Tomcat. See below for more detailed changelogs.

Many thanks to Inigo Surguy for his contributions to this release.

Cheers,
Richard Cyganiak
