# I'm starting to get the "Web" part of Semantic Web. Until now, it # hasn't been at all apparent how it would come about (even with # TimBL's little "zip" graphs), but with N3 I'm starting to get it:- @prefix s: <http://lists.w3.org/Archives/Public/semantic-web/2001Jan/0001.html> @prefix foaf: <http://xmlns.com/foaf/0.1/> s:surname = foaf:surname . # I would also liked to have put the following equivalence statement # in Notation3:- # s:firstNames = foaf:firstname . # But the properties outlined here aren't exactly equivalent (look at # the schemas), therefore, I suggest a sign to say that something is # *roughly* equivalent:- s:firstNames @= foaf:firstname . # Anyway, the point of all of this is that s:surname in my certain N3 # database is equivalent to foaf:firstname in Dan Brickley's FOAF # vocabulary. # However, I could put this in my Schema for "s:", but a piece of # RDF utilizing "foaf:" wouldn't know that mine is equivalent because # it wouldn't be declared in Dan's FOAF vocab. (unless I asked him). # Therefore, my question is "is there anyway of maintaining an open # database, where people can just enter the details of their vocabulary # term, and say that it is equivalent to mine?" and also "is this necessary?", # and "what if the vocabularies aren't in fact the same?". # On reflection, we are assigning the FOAF as default when I use my # schema to say that my term is equivalent to his... so it would only be # necessary to say that for *my* schema, and schemas that use my N3 # nerm. Therefore, it looks like something like the system I just proposed # wouldn't be required to make an SW work after all. What we *really* # need are more people putting terms up and sharing them as widely as # possible... and that's a whole other story :-) # BTW "#" is an N3 comment. Thus this is proper N3. # See my signature for more details of "linking it all together". # Kindest Regards, # Sean B. Palmer @prefix t: <http://infomesh.net/2001/01/n3terms/> . [ t:name "Sean B.
