Yes, I think it's worth pursuing.  Widely used catalog tools like GeoNetwork
and ESRI Geoportal map metadata elements into an abstract metadata model
(e.g. the 'property-meanings.xml' in Geoportal) , which is currently
internal and not documented (although they use various Dublin core, FGDC,
and ISO concepts). Better metadata interoperability could be achieved if
these abstract models were formalized and shared. I've made a cut at a model

defined to
