ANN: Sesame 2.0-ALPHA-1 released

Sesame 2.0-ALPHA-1 release: SPARQL, context, transactions, REST API

We are very pleased to be able to announce the first alpha release of
Sesame 2. Sesame 2 is a complete revision of the Sesame framework, with
a number of new main features:

* A revised Repository API that is much more targeted at embedded use of
* Support for context/provenance, allowing you to keep track of
   individual RDF data units (like files, for instance).
* Proper transaction/rollback support.
* A REST-ful HTTP protocol that includes support for the SPARQL
   protocol[1] and SPARQL Query Results XML Format[2] Last Call Working
   Drafts from the W3C.
* Support for the SPARQL Query Language[3], which was developed by Ryan
   Levering in a separate open source project:

Documentation for Sesame 2 can be found online:

  - User Documentation (SeRQL 2 manual, code examples):

  - System Design Documentation

  - JavaDoc

The current release is an Alpha release, which means that some parts of
the revised API may still undergo changes until the final release, as a
result of user feedback (and we strongly urge you to use this
opportunity!). Furthermore, Sesame 2 is not yet feature-complete: for
example, the Web interface and the RDBMS backend are not yet available.

Nevertheless, we trust that the new features will get you excited about
what's coming in Sesame 2, and we invite you to take her out for a spin
and report your experiences back to us.
