Elmo 1.3 September 16, 2008

This release fixes a few important bugs found in the previous version and has received significant changes in the code generation model. Compiling an ontology into a jar is now, not only more efficient, but has also been significantly enhanced thanks to the contributions from Zepheira. It is now possible to declare method interfaces and implementations directly in the ontology. This allows projects to use the ontology as a complete formal description of the concepts and behaviours of a given domain. For more details please see the Elmo User Guide.

Sesame 2.2 September 12, 2008

Sesame 2.2 is a considerable step forward for Sesame. Apart from the usual bug fixes, it features a new Mulgara store, a better query optimizer and an extended and improved web front-end (Workbench). Sesame now also has supports query time-outs, loading of zip and gzip streams and store locking.

Mulgara SAIL 2.2 September 12, 2008

This marks the first stable release of the Sesame driver for Mulgara. This release depends on Mulgara 2.0.5, which is included in the lib directory of the openrdf-mulgara-sail-2.2 files. This release maps blank nodes between the Sesame interface and the underlying Mulgara database, and it does not guarantee blank node ID or Java BNode reference preservation in all situations. BNodes are also not support as contexts. Most of the effort in this release has been on the stability of the Sesame driver, as a result only inner joins are being optimized in this release. The Mulgara driver files can be found with the Sesame distribution files.
