The page http://www.w3c.org could be an SI for the W3C. In this case an SI is the same as a URI. SI: http://www.w3c.org subject: "the W3C" URI: http://www.w3c.org resource: "the W3C" If this is the case then, yes RDDL uses SIs. Steve Newcomb and I once had a discussion regarding the difference between a TM: "subject" and an RDF: "resource". My understanding was roughly that an RDF "resource" encompasses both a TM: "subject" as well as a "topic". > > A published SI is one that's available to the general public, > having been promulgated by someone for the purpose.

The definitions for these things seem too wiggly for me to have much confidence in any such assertion however but I am happy if anyone is in an authoritative position to do so. Jonathan
