"This version of the Jena toolkit is a preview release of Jena 2. It has considerably less functionality than the current Jena 1 release (no DAML support, no persistenence support, no reification support). It is newer and thus less well tested in the field. However, it does have fully compliant support for datatyped literals, parsers and writers that are fully conformant with the RDFCore WG last call drafts and a preview of the proposed support for RDFS inference. The RDFCore team intend to complete the functionality missing from Jena 1 as soon as possible."
The tests seem to work fine. This is great I can get to play with datatyping and inferencing.
