[Iswc2006metadata] [Fwd: Linked data for ISWC??]

Mon Nov 6 18:42:00 GMT 2006

Hi Daniel and Tim,

I like the idea! Unfortunately, this might not happen during the  
course of this conference (except someone on the list shouts "here!"  
and can implement it until tomorrow). However, for the planned  
corpus.semanticweb.org service (which will be a persistent store for  
SW conference data, starting with this year's ESWC and ISWC data as a  
seed set) this is something we should definitely implement.

Correct me if I'm wrong, but in that case all the URIs of all the  
objects in the dataset should be in the corpus.semanticweb.org domain?

Cheers,
Knud
