In the 60th joint meeting of the CIDOC CRM and ISO/TC46/SC4/WG9 & 53rd FRBR/LRMoo SIG, upon discussing issue 666, the SIG resolved to start a new issue to update the scope notes of the temporal primitive properties of the CRM.
HW: WS to redraft the scope notes of the CRMbase temporal primitive properties, in particular the “corresponds to” bits that are unclear.
CEO, SdS, OE volunteered to proofread them.

HW by Wolfgang Schmidle (14 October 2025)
Wolfgang shared the following piece of homework for issue 702 with the SIG.
HW
In the 61st joint meeting of the CIDOC CRM and ISO/TC46/SC4/WG9 & 54th FRBR/LRMoo SIG, the group reviewed the proposal by Ws to deprecate the statements of the sort "This property corresponds to a disjunction (logical OR) of the following Allen temporal relations (Allen, 1983): {enumeration of relevant Allen relations}." in the temporal primitive properties and move them to CRMarchaeo (where the Allen Operators have been moved to).
Decision:
The SIG decided against deprecating the reference to Allen operators in the temporal primitives' definitions.
- N.b.: The migration instructions for the now deprecated Allen operators can be found both in CRMarchaeo (introduction and respective properties) and the appendix of all the releases of the CIDOC CRM in the 7.X.X strand –for the ISO version 7.1.3, see pp. 232-233.
HW:
- WS will consult the migration instruction and see whether it can be referenced without overbearing the CRM with external references to harmonized extensions.
- He will also reconsider the equivalence of “AP22 is equal in time to” and the respective temporal axiom properties, and the examples provided by DH about the Neolithic petroglyphs of Lake Onega and the White Sea –see here.
For the details of the proposal and the ensuing discussion --see here.
