That is also correct, you would have to do this: <div property="a:b" datatype="rdf:XMLLiteral"><foo>bar</foo></div> which would result in this triple: <> a:b "<foo>bar</foo>"^^rdf:XMLLiteral . Doing this, <div property="a:b"><foo>bar</foo></div> would result in this triple: <> a:b "bar" . > We gave a special role to the @datatype="" in this respect and I think > it is essential to keep that.

Anybody at a semantic search provider that could help us figure out a rough number (percentages?) of how many XMLLiterals you have in your triple store vs. other types of triples? Any chance we could get a sample set of triples? We could analyze some of the data by seeing if XMLLiteral is allow-able via rdfs:range? Michael, could DERI help us out with this in some way through the Sindice triple store? -- manu -- Manu Sporny (skype: msporny, twitter: manusporny) President/CEO - Digital Bazaar, Inc. blog: Bitmunk 3.1 Released - Browser-based P2P Commerce http://blog.digitalbazaar.com/2009/06/29/browser-based-p2p-commerce/
