There is now a sentence about subsets of rdfs:Resource generally, in section 3.3: -------- Since ICEXT(I(rdfs:Resource)) is the universe, everything has rdfs:Resource as an rdf:type value, and every class is a subclass of rdfs:Resource.Such assertions would be redundant, therefore. Similarly, some domain and range assertions are omitted from the above table; in those cases, the domain or range of the property may be taken to be rdfs:Resource, i.e. the universe; such range and domain assertions are essentially vacuous. --------- Pat -- --------------------------------------------------------------------- IHMC (850)434 8903 home 40 South Alcaniz St. (850)202 4416 office Pensacola (850)202 4440 fax FL 32501 (850)291 0667 cell phayes@ai.uwf.edu http://www.coginst.uwf.edu/~phayes s.pam@ai.uwf.edu for spam
