That's the sort of approach I would be interested to hear more about in
this group. METS and PREMIS are both implemented in XML, presumably
because of its support for extensibility and integratability of
applications in different domains - through schemas, namespaces, XPath,
XSLT, etc.

METS and PREMIS (to say nothing of EAD, DC, RDF...) each address
distinct domains, so I would think research into integrating these is 
best conducted as a separate activity, based around XML Schemas 
optimised for interoperability.
