I'm not sure that data uri's are in fact isomorphic with literals as defined in m&s. Consider: <rdf:Description> <foo:bar xml:lang="en">weekend</foo:bar> <foo:bar xml:lang="fr">weekend</foo:bar> </rdf:Description> With literals this would be: _:a <foo:bar> "weekend"-"en" . (I've invented this syntax for lang attrs) _:a <foo:bar> "weekend"-"fr" . with data uri's it would be: _:a <foo:bar> <data:text/plain;weekend> . <data:text/plain;weekend> <xml:lang> <data:text/plain;en> . <data:text/plain;weekend> <xml:lang> <data:text/plain;fr> . The later is not isomorphic with the former. Brian
