  Hi All,

  Working with protege recently, It can generate both an RDF
  Schema and separate instance documents conforming to the
  schema; however, there is no direct, explicit link between the RDF Schema
and
  its instance document.  Why not?

  It isn't needed. The terms in the RDF schema are defined in a namespace,
and by referring to any terms in that namespace instance statements are
using the meanings defined in that namespace, i.e. as in the schema. How a
system implements its handling of this information is up to the
implementation - if they are going to e.g. do some kind of validation with
it, then a likely scenario includes a local copy of the RDFS document.

  I notice that the RDF Schema spec and the Primer are both silent on
  this issue.  As this is different than the process for XML documents,
  I would think an explanation or justification is in order.

   Errm, I've not even got to the end of the Primer yet in the latest
edition, but I'm sure it's in the suite somewhere.
  C heers,
  Danny.
