Jonas Liljegren has announced the first alpha release of Wraf, a framework written in Perl for applications and data defined as RDF triples that can be stored within different distributed storage sources.

Liljegren explains how the exclusive use of RDF to design a system could lead to the Semantic Web:

Wraf implements a RDF API that hopes to realize the Semantic Web. The framework uses RDF for data, user interface, modules and object methods. It uses interfaces to other sources in order to integrate all data in one environment, regardless of storage form

RDF::Service, the Perl module made available in this alpha release is intended to work as a daemon for requests and provides a key part of the framework:

The system will use intelligent caching and optimizations in order to gain in speed without sacrifice any flexibility. A persistent backend service daemon will take requests from clients in mod_perl. Other non-browser interfaces could also use the service.

Built on experience from the RDF Schema editor, Wraf is optimized for "the really heavy use of types and subClassOf and the constant use of label in the development environment."

Wraf is free software and this release is shipped with an interface to a PostreSQL database.
