Hi Marco, all, We have been using numerical identifiers in OBI, the Ontology for Biomedical Investigations, and formalized this via the policy Alan sent out earlier (see http://www.obofoundry.org/id-policy.shtml) The OWL file is available at http://purl.obolibrary.org/obo/obi.owl. You will see that all entities have a numerical URI (individuals, classes, properties...).
