Hi All,
I wonder if the definition of 'related metadata' in the proposed
abstract model needs to be extended. There seems to me to be
some inconsistency in the document. At present it says:
'Related metadata: A metadata record that describes a resource
that is related to the resource described by a DC metadata record'.
Igmoring that definition for a moment, the words 'related metadata'
imply to me several different things and I suspect people are using
it to means all of these:
(a) More metadata about a resource that there is no appropriate DC
property for. Where metadata is encoded as XML the DC in XML
guidelines give examples of this as 'mixed' metadata.
(b) The same metadata as in the DC property fields, but encoded
using metadata properties from a different namespace.
(c) A combination of (a) and (b).
(d) Metadata about a related resource.
(a, b, c) are in fact encodings of application profiles.
I'm a bit unsure about (d). It implies I could include in a DC record
for a journal article metadata about other articles that the article
references, using dcterms:references. Doesn't this break the
principle (1-1?) that a DC record for a resource should not include
metadata for another resource? Or is this document an attempt ot
relax that rule, reflecting that in reality people are creating records
that include related metadata?
Later in the Abstract Model, DCSV is defined as a labelled string,
and that it should be treated as related metadata. This seems to
be using 'related metadata' as in (a,b,c) in some cases. Period,
Box and Point are giving more, or more precise, metadata about
the resource itself not about a related resource. The now defunct
DCMICite was providing more metadata about the resource, for
which there was no appropriate DC property, not metadata for a
related resource. Though the Vcard example is metadata about a
related resource.
So does the Abstrat Model document also need to include
something about mixed metadata / application profile?
