There was a suggestion on the list last summer that transformation grammars could be used to formally specify the translation of RDF XML to triples. A quick search around the web revealled that such grammars were proposed in natural language processing, but I didn't find anything immediately useful. I liked the idea of formal definition of the transformation. I also thought it would be good to have an 'executable' specification, i.e. one that we could execute against test cases and would spit out the triples. My first thought was to use XSLT to define the transform, but that turned out pretty unreadable. My second attempt has been to produce and attribute grammar for RDF. It turns out that an attribute grammar works reasonably well, and there is a simple, possibly automatable, way of turning the attribute grammar into an XSLT transform. An experimental version can be found at: http://www.bmcb.btinternet.co.uk/2001/rdf/exec-grammar/spec.xsl The attribute grammar can be found in the header comment, and the XSLT is executable, though probably buggy.
