Conventions and top-level ontologies for RDF

I pointed out at WWW9 developer's day that to aid metadata sharing
and reuse, a directory, 
(such as http://www.ilrt.bris.ac.uk/discovery/rdf-dev/roads/)
should also list top-level ontologies and 
lexical/structural/syntaxic conventions.

As a step in that direction, I have published proposed conventions 
plus a top-level ontology of 80 general classes (some derived from 
the Frame ontology of Ontolingua) and 120 properties/relations, e.g.
logic, thematic, spatial, temporal, attributive and ordering relations.

See http://www.inria.fr/acacia/personnel/phmartin/RDF/proposals.html

For instance, I explain why actions should not be represented via
properties but only via resource classes, and I propose an extension
of Tim Berners-Lee's "forall" construct for universal quantification.

I hope this e-mail will initiate some discussions and further 
suggestions to refine these conventions and top-level ontology.

Many thanks. 

Philippe
