Issue 550: Time-span for instances of I11 Situation
In the 50th joint meeting of the CIDOC CRM SIG and SO/TC46/SC4/WG9; 43nd FRBR – CIDOC CRM Harmonization meeting, upon discussing Issue 425 the SIG resolved to start a new issue where to define a property linking I11 SItuation to the time span over which it holds.
The scope -note of I11 Situation anchors a particular observed state of affairs to the time-span over which it holds. This information is missing from the class-definition, as there is no property linking it to this temporal aspect.
Decision: to introduce a property linking instances of I11 to their respective E52 Time-Spans.

I think we decided not to fill the class examples with e-numbers of things within the noun phrase. Otherwise I agree.
I believe we need a property "Jxxx held at least for: E52 Time-Span"
"This property associates an instance of I11 Situation with the instance of E52 Time-span for which it was asserted. It constitutes part of the identity of this situation. Any different association of a time-span even to the same constituting propositions of this situation will identify another instance of I11 Situation.
Note that the respective situation may have had shorter duration than the one given by the property P82 at some time within to the associated time-span, but the same propositions may quite well have prevailed for longer and other times. In order to make a statement about how long at least the propositions of that situation uninterruptedly prevailed, the property P81 ongoing throughout should be used for the associated time-span.
There is no means to declare that the propositions of that situation did not occur again ouside the given time-span."
