Dear George,
We use the “type" because it implies necessarily if it is a perdurant or
endurant, person etc. If it does not, it is ill-defined, and has no
place in a Thesaurus (see the AAT). If the categories of a thesaurus fit
the CRM is a mapping problem.
No problem for retrieval at all. Just a programmers job.
Place types are relatively rare, such as "river" "lake", "city". The
UMLS system e.g., listed some decade ago I think 10 or 20 million types,
but less than 100 properties, corresponding to at most 200 classes.
Therefore, P2 is not "cheap", but it does never replace meaningful
properties.
Best,
Martin

Dear Martin,
I'm glad to hear you have encountered such cases as well and find it a
potentially good path to explore. I find myself in a conundrum
thinking about (my own) proposal because of the vagueness of the word
'entity'.
What I find typical in many modelling exercises regarding bibliography
is that aboutness can be about the following real world, particular
things:
subject - E55
geographic location / place - E53
person / corporation - E39
So already there is typically some breakdown of aboutness into
different main kinds of real, particular things that a work can be about.
When I reflect on the property 'represents entity of type', the
examples are all of endurants. This may be an accident but it makes me
wonder about whether a new specialization of aboutness to refer to
'things of type' would best follow this general pattern (the entity
could be a perdurant, endurant, place etc.) or if the property would
better be more specialized. (is about temporal event of type, is about
persistent item of type, is about place of type).
It just occurs to me that in the context of retrieval if the property
were not more specific to perdurants / endurants etc. then it could be
quite difficult to sort out if you want to find works about events of
type vs works about things of type vs works about places of type etc.
This is not a problem when the aboutness property is about a
particular because we can use the class to differentiate. 'Given me
E73 about E39' automatically culls the data down to the aboutness
regarding actors. If the new property pointed to E55, then we would
not have this facility.
So... hopefully still a good idea but seems to have some complications
to be thought through.
Best,
George

Dear George,
I think this is a very good idea. There are thousands of
archaeological publications listing items etc. of certain types,
often with reference to museums keeping them, but library practice
will only register overall aboutness. Museum records cite such
publications explicitly, but the inverse has never been exploited
systematically.
Cheers,

better phrasing, 'about a particular thing that is known
categorically'
Eg Sales Record about 'Sale Event'

Dear all,
Recently work is on-going on a new property 'represents thing
of type' which is distinct from 'represents' (again that
particular vs categorical distinction).
https://cidoc-crm.org/Issue/ID-476-pxx-represents-entity-of-type
I am confronted with cases of an information object
being about not a particular thing but a category of thing...
in my case event types but I guess it could be object types.
Of course the existing 'about' property is sufficient but it
doesn't allow to differentiate that it is not just a type but
about an as yet unknown X which was of type Y... It seems to
me similar to the other new property we are working on already.
Does anybody else have cases like this? Any interest in a new
parallel property like that OR a solution that requires no
new properties but also doesn't require semantic back flips
to understand?
Best,
George
