Re: VCal namespace

Exactly: given that at the scale we operate we can not afford complex 
reasoning to  figure out the relationship between two ontologies (even 
if they are 99% same and they differ in a single axiom). So without an 
agreement on URIs there will be no interoperability.

Good news is: it's not too late... we are still a small group and there 
is room to change things. We can change on our side, Sindice can change 
on their side... but the window of opportunity is closing. So the 
question: if the Semantic Web is to start today, what namespace should 
people use to represent hCalendar and other calendar information in RDF?

Cheers,
Peter
