B, b, b boca gives you an enterprise ready RDF store

IBM Semantic Layered Research Platform announced the release of Boca: "Boca is designed to make it possible to build multi-user, distributed RDF applications" Supports named graphs, security, replication, revision history and JMS notification of changes.

The users guide lists some other interesting features such as a client stack with "a fair amount of compatibility with HP's Jena API" and text indexing using Lucene. Based on the configuration it looks like it requires DB2 or Apache Derby as well as Java 5.

Via, IBM SLRP Release.

RDF on Lambda

RDF and Databases "Some RDF research dropped me to a nice paper (PDF) from IBM discussing RDF with relational databases. This combination can replace half-baked application data mechanisms. These crop up regularly in my consulting work. Think nested directories of Windows INI files and brittle, binary files breaking on minor design iterations. The pain, the pain."

"There are several projects in this domain. My favorite so far is OpenRDF Sesame. It supports querying at the semantic level. It seems more mature than others, having derived from previous efforts, and works with both PostgreSQL and MySQL as well as Oracle. An abstraction layer called SAIL makes Sesame database-agnostic. Sesame even sports a stand-alone b-tree system, or in-memory operation, if you don't want an external database."
