ANN: Sesame 2.0-final

Dear all,

After two years of intensive developement, Aduna recently released
Sesame 2.0. Sesame 2 is a major revision of the Sesame RDF storage and
querying framework, building on the feedback that has been gathered
during the past years. A lot of improvements have been made to various
APIs as well as the framework as a whole.

A short introduction for those who are new to Sesame:

Sesame is one of the major open source frameworks for RDF storage,
querying and inferencing. The framework is fully extensible and
configurable with respect to storage mechanisms, inferencers, RDF file
formats, query result formats and query languages. Sesame is both a Java
library as well as an RDF server and is distributed under a BSD-style
license. Ports and client libraries for other programming languages are
available as well.

So what's new in Sesame 2? Well, to highlight just the most prominent

- Support for the SPARQL Query Language, SPARQL Protocol and SPARQL
   Query Results XML Format, which have just been promoted to W3C
   Recommendation. Please ignore the implementation overview that is
   referenced from the SPARQL press release; except for DESCRIBE-queries,
   Sesame now supports all SPARQL features.

- Support for contexts/named graphs, allowing you to keep track of
   individual RDF data units (like files, for instance).

- Much more targeted at the use as a library, while retaining all the
   powerful server features.

- A JDBC-like API with a complete transactional model.

- An easier to use REST-ful HTTP protocol for client-server
   communication with considerably less overhead.

I'd like to thank the huge amount of people who have helped us to reach
this mile stone by testing the software and giving feedback on it.
