It might be useful to point out here that Dublin Core identifiers are 
repeatable, and are not necessarily URLs. Other kinds of identifiers, like 
ISBN or ISSN numbers, for instance, are valid identifiers.  Confusion may 
well ensure thereby, but limiting to one identifier in this world is not 
realistic.  But it just goes to show that there's still no substitute for 
"knowing your data" ... ;-)
