hi Jeen
 u said OIL has RDF syntax ?
i read "OIL in a Nutshell" 2000, in side
author gives something like this 

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

as a example of OIL.
i assume this one is OIL syntax...

thank u
