Coming soon: Jena 2.4
Target date for release 2.4 completion: April 30th.
Very timely, with the Jena User Conference in May.
The main new feature seems to be support for assembler specifications, which are “RDF descriptions of how to construct a model and its associated resources, such as reasoners, prefix mappings, and initial content.â€
This means applications that can work on top of different kinds of RDF models (e.g. RDF browsers, graph visualizers, RDF servers) now get a standardized config file format for setting up the models. This also means someone (I, most likely) will have to write an assembler for D2RQ models.
