Paul Miller, on behalf of the CIMI group, has suggested that
we include a new value in the list for DC.Type - "event".
Here is an extract from his mail:

I'm inclined to support this proposal. It might
help us out of quite a few tricky ones. I forsee
that the "sophisticated interpretation of the 1:1 model"
that Paul refers to could well address some problems that
have been raised relating to the underlying datamodel of
a resource description system. This is particularly
important as we extend the reach of DC beyond electronic
resources. For example, Lorcan Dempsey has given an
example drawn from IFLA:
> Abstract work - Hamlet as intellectual creation
> Expression - Hamlet as text or Hamlet as performance or ..
> Manifestaion - Arden 1956 edition of Hamlet text, ...
> Item - one copy of the above, ...)
"event" clearly helps us out here as a type for the second item
on the list. I guess there may be a question about how useful
a "resource" of type "event" is to future users, (can't really be
retrieved!) but it will certainly be useful in descriptions of
transformative stages in a chain of related resources.
"event" could also be seen as having a certain symmetry with
"physical object" - the latter describes resources which
are fundamentally unique in space (though they may move
realtive to a particular frame of reference) - events are
closely tied to a moment in time (and also, possibly, space).
I would like to propose that we add "event" to the list of
blessed values for simple DC.Type, with the following gloss:
event
non-persistent resources tied to a moment in time.
These will often involve the transformation of source
resources (such as scripts, scores, etc) and may be recorded thereby creating derived resources (eg. on
film, tape, or as a transcript) but have a fundamental
identity separate from either of these. For example -
exhibition, web-cast, performance, battle, trial, wedding.
If there is no disagreement, I will add this to the working draft
at http://www.agcrc.csiro.au/projects/3018CO/metadata/dc_tf/
on Friday 18th September.
