[Crm-sig] About ... entity of Type?

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

So... hopefully still a good idea but seems to have some complications
to be thought through.
