Peter - I think that there is a major flaw in your example,
concerning the DC.Identifier elements. Your example metadata
purports to describe a person, whereas the identifiers that
you give identify
1. a web page
2. an e-mail address.
Neither the web-page or e-mail address are identifiers for
instantiations of Stu. Arguably, they are resources in their
own right. The 1:1 principle, which was extensively discussed
at DC-5, asserts the notion that DC metadata should refer to
a single specific instantiation of a resource.
"Identifier" should really be some kind of unique code for
the resource itself. Better examples in the case of a person
might be SSN, TFN, etc.
However, pursuing this line a little further, while the web-page
is relatively easy to describe in DC, the e-mail address is
trickier (I guess, if pushed, I'd suggest it could be
DC.Type="interactive" since it only has meaning when interacted
with, but I'm not real confident here). Furthermore, both
of these resources are clearly _related_ to Stu-the-person,
and thus it should be possible to provide pointers between the
metadata for each and Stu-the-person using DC.Relation. I wonder
what Relation-type should be used? For the web-page either
"IsBasedOn/IsBasisFor" or "References/IsReferencedBy". However,
for the e-mail address it is not at all clear.
The choices are (see Relation working-group report [1] )
IsPartOf/HasPart
IsVersionOf/HasVersion
IsFormatOf/HasFormat
References/IsReferencedBy
IsBasedOn/IsBasisFor
Requires/IsRequiredBy
Given the two problems described here for e-mail address
(which DC.Type? and which DC.Relation-type wrt the person)
maybe I've argued all the way back around to e-mail address
actually being a valid "identifier" for a person.
Doesn't feel quite right.
Comments, anyone. (esp. David, Misha?)
(yr values for DC.Subject are a little wierd too - they are not
really keywords applicable to Stu-the-person - perhaps the
contents of his mind, but ...)
