Dear all,
Martin and I have had a very short discussion about how to model
information from old and not properly written catalogues from the
entographical museum in Oslo:
"We are working on a database for ethnography (the museum) and have as an
objective to make this database as CRM-compatible as possible. As usual the
real data are XML-tagged aquisition catalogues (19). In some cases one will
find entries simplely describing a mask very briefly and then at the bottom
its written Borneo. According to the model thought out by the ethnographers
this could mean: made or used (by people) or collected/bought (by
ethnographers) on Borneo. According to the model thought out by the
ethnographers this could mean: made or used (by people) or collected/bought
(by ethnographers) on Borneo. [Allthough if pressed they tend to deny
everything except that there seems to be a connection]."
Due to the really unclear connection it is tempting (at least for my
collegues and me) to model this by introducing an empty property P0 and
using a E13, attribute assignment to represent the fact that the connection
is documented in a certain (identifiable) catalogue. I got the following
answer from Martin:
"Physical Object - was present at - Event - took place at Place.
I don't think you need more. You could even classify the event with
a "MAKING USE or CoLLECT" Type. Totally precise. "
Martin is completely right that it iss totally precise. Since then we have
discussed the problem with Stephen and have been informed that we are not
the first to suggest a P0. A P0 will be useful from a information-logical
point of view. However, I see the point that the introduction of such a
thing will make it too tempting to collaps a mapping in to CRM into P0s.
Thus Martin's solution should be selected. The use of a "MAKING USE or
CoLLECT"-type will for many persons be a little unfamiliar. But in a proper
thesaurus it is fine.
Praeterea censeo E3 Condition State esse delendam
