transform XML and XHTML to RDF

 GRDDL is a W3C Recommendation
 for extracting RDF data from arbitrary XML and XHTML
 via a transformation, typically written in XSLT.
 See <http://www.w3.org/TR/grddl/> for more details.
 .
 This module implements GRDDL in Perl.
 It offers both a low level interface,
 allowing you to generate a list of transformations
 associated with the document being processed,
 and thus the ability to selectively run the transformation;
 and a high-level interface where a single RDF model is returned
 representing the union of the RDF graphs
 generated by applying all available transformations.
