Dear All,

As the version 3.4.2 of the CIDOC CRM will be submitted to ISO as DIS
before the next CRM-SIG meeting, (which does not prevent us from making
editorial improvements after that), here however a conservative extension
to be resolved now:

a) As I announced in the last issue, the proposal to generalize the properties
under E13 Attribute Assigment. This allows basically to introduce the discourse
about properties in general as historical fact, but also naming activities and
others. This has always been the intention of the CRM, so this proposal closes
an important gap in reasoning, actually the last one the CRM SIG could identify.

See attached file for the full proposal.

b) Now that all classes have been reviewed, one more conservative change request
appears:

       E6 Destruction. P13 destroyed (was destroyed by): E19 Physical Object

should be changed to:
         E6 Destruction. P13 destroyed (was destroyed by): E18 Physical Stuff

   Pro: Features can be destroyed, like faces of statues, caves by earthquake 
etc.
   Con: Destruction of a feature is a modification of the object. No need for 
this change.
   Pro: It is counterintuitive and lacking precision to describe destruction of
        Features on the surface of earth as modification of the whole planet.

Both changes are conservative (monotonic) in the sense that no current data in
a CRM implementation is invalidated by that. Both changes have the agreement of
the CRM-SIG Steering Group.

Please
  VOTE FOR

   a: Pro / Con
   b: Pro / Con

Until Wednesday, 17/9/2003.

Best regards,

Martin
