Dear Philip,
I share the opinion of Steve. A general association of historical nature
is utterly incompatible with the whole philosophy of the CRM. If a
source refers some things as related in an unspecified way, we can only
blame the source as information object for it. This could cover the "if
you are interested...then...". We need some least semantics, otherwise
any reasoning breaks down. This can be done by interpreting the
respective vocabulary, if a relation type is provided. Minimal semantics
are for instance parthood, presence, influence, similarity (parallels or
causal), common type, etc.
Users should be forced to be more specific. It is hard to imagine, that
a user knows a relationship but nothing about it.
I'd argue that such links are a result of underspecified documentation
practice, and not of indeterminacy of scientific knowledge.
Of course, you can add a non-CRM compatible extension ;-), if you have
no better knowledge of the documented fact.
Other opinions?
Best,
Martin

I would probably model these in one of two ways depending on the
nature of the general association.
A] As parts of a larger physical man made thing; so in your example
the telephone box and the exchange a part of a regional
telecommunications system which in turn is part of a national
telecommunications system.
B] As both being present/participating in a period, event or activity;
so this Napoleonic sea fort and this Napoleonic military canal are
constructed as events that form part of the Napoleonic British Defence
Period.
I suppose as a last resort you could create an Information Object
which refers to them all and name the Information Object as “A list of
things which I am interested in for X reason”; your essay of why could
then be attached via P3 has note. In this case what you are modelling
is not the relationship between the things but your/your
organisation’s believe that there is a relationship (however tenuous!)
between them.

*Subject:* [Crm-sig] Associative relationship mapping
Hi all,
The Arches project moves on a pace and is in the process of modifying
the graphs for version 4.
In the original graphs we used a British Museum extension property
(PXX_is_related_to) as a work around to allow us to represent the
general association relationship we had in legacy datasets. eg. this
telephone kiosk has a general association with this telephone exchange.
We now want to continue to be able to model a general association but
the only property available P69 has association with (is associated
with) is restricted in its domain and range to E29 Design or Procedure.
How do we model the ‘If you’re interested in that you might be
interested in this’ nature of the general association between two
physical man made things?
All thoughts appreciated.
Phil
