I did not find this a rookie question at all.This seems to get to the heart of some of the real difficult issues in Semantic Web. My perspective is different from yours, and a resource description that I author is a description of the resource from my perspective; a resource description that you author is a description from your perspective. If I have some detailed application that depends in some subtle way on my description, I may want to ignore your version; on the other hand, a third party might want to use both of our points of view. One way of tacking this problem is to have three graphs for this case: Gj, Gu, G= Gj contains triples describing my point of view Gu contains triples describing your point of view G= contains the owl:sameAs triples Then, in some application contexts, we use Gj, sometimes Gu, and sometimes all three.

Sorry if I'm asking too basic questions. I'm still a rookie at this :D Umutcan On 15-03-2013 19:38, Kingsley Idehen wrote:On 3/15/13 1:05 PM, Umutcan ŞİMŞEK wrote:My question is, does LODD use owl:sameAs properly? For instance, are those two resources, dbpedia:Metamizole and drugbank:DB04817 (code for Metamizole), really identical? Or am I getting the word "property" in the paper wrong?The question is always about: do those URIs denote the same thing? Put differently, do the two URIs have a common referent? ## Turtle ## <#i> owl:sameAs <#you>. ## End ## That's a relation in the form of a 3-tuple based statement that carries entailment consequences for a reasoner that understand the relation semantics. Through some "context lenses" the statement above could be accurate, in others totally inaccurate. Conclusion, beauty lies eternally in the eyes of the beholder :-)
