[bxmlt] Eric Prud’hommeaux – SAWSDL

Eric shows off SAWSDL. I didn’t know about it before. It defines mappings from Web Services to RDF. The basic idea is to start with a WSDL description of the web service. Then add a few attributes that describe how bits of content in the XML messages map to an equivalent RDF description of the message contents. It uses SPARQL-like fragments and XPath. The fun is that the mapping works in both directions – from webservice results to RDF, and from RDF messages to webservice requests.
