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.
