Issue 634: What is required for expressing current knowledge?

Starting Date: 
Working Group: 

In the 55th joint meeting of the CIDOC CRM and SO/TC46/SC4/WG9; 48th FRBR/LRMoo SIG meeting, upon discussing issue 616, the SIG resolved to start a new issue where to investigate what is required for expressing current knowledge. After this has been agreed upon, the SIG may discuss deprecating P50/P52/P55 and the repercussions of doing so.

Things to take into consideration: properties are means to express some knowledge, for ownership, the qualifications current vs former, represent knowledge on the ownership (and changes thereof) for some object in time. The problem stems from the effort of trying to express a complex property (the ownership) in simplistic terms.

In the 58th CIDOC CRM & 51st FRBR/LRMoo SIG Meeting, the SIG resolved to close the issue given that

  • no HW had been assigned to any SIG members for it (so it probably did not mirror a real need in terms of conceptual modeling", and 
  • (more importantly) there is a general discontent for the “has|is current xxx” properties, as they require a lot of curating and present a simplistic view of the world (to the extent that there have been proposals to underrepresent them –if at all –in the graphical overview of the CRM).       

Decision: Issue closed
