RDF Twig: XSLT Extension Functions for Accessing RDF Graphs
This is the permanent status page for RDF Twig. RDF Twig is a set of XSLT extension functions for Saxon and Xalan that provide dynamic access to RDF graphs stored in the Jena repository. Version 0.96, supporting the Saxon 8.4 API, is now available.
RDF Twig accesses RDF graphs from XSLT. This version of RDF Twig supports the Saxon 8.4 API.
The current release is 0.96 from 25 Apr 2005. This is the third, alpha release; it is implemented in Java and runs on any platform that supports XSLT and Jena 2.x. You can get “rdftwig” from the download page on SourceForge. It is available under the Apache Software License.

0.95, from 28 Oct 2004 was an alpha release built on top of the Saxon 8.1.x API.

Comments
Very interesting. I'll be building it soon (after I install and test the requirements). In the mean time, does it support loading from rdf/xml or n3? What about Saxon's experimental XSLT 2 support?
The main feature of the 0.95 release is support for Saxon 8.x which is the Saxon version that provides experimental XSLT 2 support. The extensions load RDF/XML, but presumably getting them to load other formats (if they're supported by Jena) wouldn't be too hard, I just haven't had any need to yet.
If you want easy rdf file loading try jena's FileManager, which handles most of the pain for you (see loadModel in particular). n3 and ntriples for no extra work :-)
Oops. Replying to old comments. Sigh...
