Dear All,
I suggest a professional approach to this question:
Please look at issue 442 and 520. Please read carefully the scope note
of E19.
Temporary aggregates are in no way specific to E13.
In particular for moving objects, but also for exhibition arrangements,
conservation etc., physically coherent items can participate in any
number of temporary or permanent aggregates.
In 1998, we followed a presentation how the National Museum in Melbourne
was completely moved. Vernon made the S/W. Traceability of the temporary
aggregates was the major issue.
No reason to regard the aggregation of activities as better. My
experience from creating collection management systems is that
documenting temporary aggregates is in many cases more reliable. Both
solutions should be mentioned, but documenting by temporary aggregates
should be in our teaching program, people stumble over it since decades
and it is very substantial. E19 scope note could even be enhanced.
Kind regards,
Martin

Conversely, I support Christian-Emil's proposed migration pattern of
using an encapsulating event to collect together the attribute
assignments. This pattern allows the transitive inclusion within
further such higher order events as well, including the typical museum
operations such as acquisition, accessioning, conservation, and so on.

Dear All,
I'd rather suggest to better group the aggregates as single
instances of Physical Object, which corresponds to the way of
handling of such "multiple items".
Best,

The Issue 700 is described in

I have created a document in the Google drive,

Migration Instructions for E13 Attribute Assignment, subclasses
and (sub)properties
In cultural heritage institutions it is common practice to
document condition assessment, measurement, classification,
observation etc. for groups of objects. This has been reflected
in the CRMbase by the quantification many-to-many of the
properties P140 /assigned attribute to (was attributed by)/ and
P141 /assigned (was assigned by)/ and their subproperties. From
v7.3.1 and on, all instances of of E13 Attribute Assignment (and
subclasses) forms a single activity applied to exactly one object
and yielding one value or dimension, which prohibits multiple
values or dimensions as the objects of one instance of E13
Attribute Assignment (condition assessment, measurement,
classification, observation, etc.). After the change one has to
replace the single instance of E13 Attribute Assignment or
subclasses with an instance of E7 Activity as the grouping event
and a new instance of E13 Attribute Assignment or subclasses for
each of the objects in question. The grouping instance should
hold the information about time, place and actor of the original
instance of E13 Attribute Assignment and a type indicating the
kind of event. Each of the new instances of E13 Attribute
Assignment or subclasses should be sub-events, that is connected
to the new instance of E7 activity via the property P9 /consists
of (forms part of)/
