Use of persistent identifiers is certainly desireable, though I am
loathe to plunge our discussions into the philosophic morass of the URN
tarpits. Seems like we've got enough morasses of our own.

Subject: Re: Relation Position: Revision 1
Re reference to "globally-unique identifier" below: shouldn't it
also be
persistent/permanent? For example, a URL is a URI but it's not
permanent.
Should we specifically refer to URNs or PURLs instead? Or, to be
non-Web
specific, DOIs?

I. Relation Semantics:
The Relation element specifies the relationship between the
present
resource and a target resource, and can be thought of as two
entities
connected by an arc, the arc being a named relationship.
The present resource is unambiguously identifiable as the
resource with
which the metadata is associated (identified in the Identifier
element).
The target resource should be unambiguously defined by a
globally-unique
identifier (one of any of several varieties in common usage:
ISBN, URI,
whatever).
