Jos: remove some axiomatic triples (triples true in every interpretation) - to avoid infinite no of facts 15:58:07 -AllenGinsberg 15:59:22 the axiomnatic typing of listmembership properties is all that's removed, right? 15:59:56 q? 16:00:00 right 16:00:46 Harold: Are any of these ideas eg "RDF-" also proposed to RDF community? 16:01:19 Jos: This is also already done in practice by practioners.
