Dear Christian-Emil,

Dear all,
THe CRM is in its basic nature retrospective. That is, it models events that has happened seen from the current point in time. The final paragrpahp of the scope note for the property P20 is not consistent with this view. If the bank (in the example) does not succeed in its take over plan because it goes bankrupt before the take over event should have taken place, then that event will never happen and will not exist. Thus P20 actually implies that an activity succeeds in it achieving its aims.

Yes, this was what we had actually in mind. The scope note is wrong.

Will be interesting to discuss planned events as extension of the CRM.
I'd suggest to make a remark in the scope note, that appropriate extensions may 
deal
with planned events, planned and realized events, planned and not realized 
events
(what is the notion of identity of a planned event, that may persist with the 
realization?)

Best,
Martin

P20 had specific purpose (was purpose of)

Domain: E7 Activity
Range:  E7 Activity
Quantification: many to many (0,n:0,n)

Scope Note: This property describes the relationship between an E7 Activity and an activity that it is intended as a preparation for.

This may involve activities in preparation for other activities, or orders and other organisational activities, which lead to some other specific activity.

P20 had specific purpose (was purpose of) does not imply that an activity succeeded in achieving its aims. For example, dubious accounting practices may be carried out with the specific purpose of enhancing share values and enabling a take-over bid. The specific purpose remains the same even if the strategy fails and the company goes bankrupt instead.
