Issue 636: update the list of property quantifiers

Starting Date: 
Working Group: 

Post by Wolfgang Schmidle (6 February 2023)

Dear All,

The list of property quantifiers in the introduction of the CIDOC CRM document is not up to date:

(1,1:0,1) and (1,n:1,n) should be added
(1,1:1,n) and (1,1:1,1) can be removed

Two changes are a result of the corrected property quantification mismatches, the other two are not.

Details are here:


Current Proposal: 

In the 56th joint meeting of the CIDOC CRM and ISO/TC46/SC4/WG9 &49th FRBR/LRMoo SIG, the SIG approved the proposal by WS to introduce the missing quantification definitions that are mentioned in the specification document. 

Arguments were made against deprecating property quantifications explanations that do not occur in the specification document.

  • The addition of new properties might result in reintroducing explanations of said property quantifications.
  • They also happen to appear in extensions –f.i. LRMoo uses (1,1:1,n)

The new property quantifications should make it in the community version (i.e. 7.2.3). Whether they also make it to the ISO version is up to PM & EC to decide.
