Re: Version 0 of the 'RIF+XML data' document "nouvelle maniere"

Hi Christian,

I've attempted to read this but found it somewhat hard to follow 
(probably just my lack of concentration, but some concrete examples 
might help).

The high level approach seems reasonable - follow Xpath data model, map 
classes to sets of element nodes and frames to elements using some URI 
encoding scheme for types and attributes.

Some of the details need work though. You talk about relative IRIs but 
surely all relative IRIs in a RIF document will be resolved relative the 
base (document location or explicit RIF base declaration). So I don't 
think you can use relative IRIs in the way you describe. Also the 
namespace resolution seems be a bit underspecified.

You use the term "sequence" a lot but as far as I can see everything is 
getting mapped to separate frame slot values and so ordering is lost. Is 
that right?
