I wasn't talking about implementing any such thing. I was talking about merging data from the different sources. You had pointed out places where the mapping couldn't work without breaking out of DL. I'm suggesting that if you want to use real-world RSS 1.0 with RSS 1.1 then you'll have to be prepared to. > And if you really want to talk to me about pragmatism, I think you > should be talking about XSLT instead of RDF anyway. Yes, that would be one route to merging. But it would help to have a mapping to begin.

No objections there, I just felt "we can't do a pure mapping so we won't do one at all" wasn't much use in pragmatic terms. > > there's a good chance the XML won't even be well-formed, let alone > > consistent with a DL.
