Re: Which datatype to use for time intervals

An interesting new bit of news on the topic today, from 
http://semanticweb.com/schema-org-chat-googles-r-v-guha//
/

    /The Semantic Web Blog/: Where do challenges still lie for schema.org?

    /Guha/: We have to get to the next level, to represent time which is
    always a challenge in plain old RDF. And we are working with the W3C
    folks on trying to come up with ways to represent time.
