Danny Ayers released Simple Semantic Resolution - RSS 2.0 Module.

Put simply: an element is added to the source RSS 2.0 document which declares "this is RDF, and here is the mapping".

It uses my RSS to RDF converter.

XR is based on the experience of making that XSLT converter. I'm going to make an XR transformation that will do exactly the same as this RSS to RDF converter. SSR is also something that needs to be generalised to all XML documents. A possible solution could be adding a "target mime-type" attribute to the xml-stylesheet processing instruction. It would look something like this:

<?xml-stylesheet type="application/x-xr+xml"
  target-type="application/rdf+xml"
  href="http://w3future.com/tools/xhtml2rdf.xml"?>

XR (XML -> RDF) is a transformation format that indicates how RDF can be extracted from a certain XML format. Once a transformation for a certian XML format is defined, RDF can be automatically extracted from every XML file in that format.

This is a work in progress, and comments are very welcome. The documentation needs a lot of work, but I hope the tutorial and the examples will be clear enough for some to play with this.
