I am pleased to announce the first release of the Jena GRDDL Reader.

This implements (my best guess at the next draft of) the GRDDL
specification:

http://www.w3.org/TR/grddl/

Download from the usual place:
http://sourceforge.net/project/showfiles.php?group_id=40417&package_id=220278

Documentation is included in the download and is also at:
http://jena.sourceforge.net/grddl/

Note:
Like all technologies that involve executing untrusted code from the
Web, GRDDL presents security issues. Please read the security related
documentation before use.

The abstract of the GRDDL primer reads:
http://www.w3.org/TR/2006/WD-grddl-primer-20061002/

[[
GRDDL is a mechanism for Gleaning Resource Descriptions from Dialects of
Languages. It is a technique for obtaining RDF data from XML documents
and in particular XHTML pages. Authors may explicitly associate
documents with transformation algorithms, typically represented in XSLT,
using a link element in the head of the document. Alternatively the
information needed to obtain the transformation may be held in an
associated metadata profile document or namespace document. Clients
reading the document can follow their nose using techniques described in
the GRDDL specification to discover the appropriate transformations.
This document uses a number of examples from the GRDDL Use Cases
document to illustrate in detail the techniques GRDDL provides for
associating documents with appropriate instructions for extracting any
embedded data.
]]

The Jena GRDDL Reader also supports transforms of HTML pages, and use of
XSLT 2.0.
