The namespace URI for treetriples is <http://djpowell.net/schemas/treetriples/1/> This URI is also an XHTML page which uses eRDF in the HEAD to make the assertion: S: <http://djpowell.net/schemas/treetriples/1/> P: <http://www.w3.org/2003/g/data-view#namespaceTransformation> O: <http://djpowell.net/schemas/treetriples/1/xslt/tt2rdfxml.xsl> Therefore any GRDDL agents will know that treetriples documents with the <http://djpowell.net/schemas/treetriples/1/> namespace can be transformed into RDF/XML using that XSLT transform. It is a bit like this example <http://www.w3.org/TR/grddl/#ns-bind>, but rather than have RDF/XML as the namespace document, it has eRDF, which is itself GRDDLable, and therefore does the same job. The result is that GRDDL-enabled software such as: <http://librdf.org/parse> can take a treetriples file such as <http://djpowell.net/schemas/treetriples/1/examples/feed-t2.xml> and parse it, without requiring any GRDDL annotations on the instance document. -- Dave
