I think this is an important point as towards the end of the workshop we
seemed (from where I was sitting anyway) to be settling in to solving
three different but interlinked problems; the embedding of Dublin Core
Element Set attributes into HTML doucments (a specific instance of
embedded metadata, the construction of a concrete canonical syntax for the
Dublin Core Element Set and the design of the "Warwick Framework" for the
exchange of arbitrary packages of metadata between consenting programs.
For my part I see the embedding of DCES attributes within HTML as a
particular mapping between the concrete syntax that the SGML boys came up
with and the limitations of the HTML DTD. I can imagine other mappings
might appear in time (PostScript structured comments, PNG extenstions,
VRML headers, IAFA templates, MARC records etc, etc) if the DCES proves to
be popular and useful. It might be worth pointing out in section IIA
that although HTML is file format that is going to get the first mapping,
other mappings to other formats should be encouraged as well. Section
IIB seems to cover the other two problems (ie: pointing out that we need
a canonical concrete representation of DCES and also the WF for
interoperability between systems).
Tatty bye,
