hi Jeen u said OIL has RDF syntax ? i read "OIL in a Nutshell" 2000, in side author gives something like this ontology-container title "African animals" creator "Ian Horrocks" subject "animal, food, vegetarians" description "A didactic example ontology describing African animals" description.release "1.01" publisher "I. Horrocks" type "ontology" format "pseudo-xml" format "pdf" identifier "http://www.cs.vu.nl/~dieter/oil/TR/oil.pdf" source "http://www.africa.com/nature/animals.html" language "OIL" language "en-uk" relation.hasPart "http://www.ontosRus.com/animals /jungle.onto" as a example of OIL. i assume this one is OIL syntax... thank u On Tue, 19 Oct 2004 21:30:08 +0200, Jeen Broekstra <jbroeks@cs.vu.nl> wrote: > > Dear Peter, > > > > Peter wrote: > > Dear all, as i read, some basic ideas i would like to enquire.
