Issue 643: P156 occupies & P7 took place at – inverse shortcuts

In the 56th joint meeting of the CIDOC CRM and ISO/TC46/SC4/WG9 &49th FRBR/LRMoo SIG, upon discussing issue 613 the SIG resolved to start a new issue concerning the relation of the fully articulated paths that P156 & P7 shortcut over, to said properties. 

Things to consider: 

• Make sure that the definition of P156 is complete wrt. the reasoning for reference spaces.
• P156 and P7 form inverse shortcuts as long as the reference space remains constant. 
• The statement found in P7, namely: “Therefore, this property implies the more fully developed path from E4 Period through P161 has spatial projection, E53 Place, P89 falls within to E53 Place, where the intermediate place is also defined in the same geometric system. Both places are defined in the same geometric reference system.” can serve as a blueprint for P156.  

AG shared with the SIG a model on spatial relations and how it overlaps with the CRM –the document can be found here. And it must be considered for issue 492 as well. 
HW: CEO to formulate the issue.
