Starting Date: 
Working Group: 

In the 54th CIDOC CRM & FRBR/LRMoo SIG meeting, the SIG resolved to start a new issue, where to discuss the properties of Sxx1 Position Measurement, a newly admitted class into CRMsci. The properties that need be properly defined are: 

  • Sxx1 Position Measurement. Oxx1 determined position (was determined by): E94 Space Primitive
  • Sxx1 Position Measurement. Oxx2 has validity time-span (is position validity for): E52 Time-Span
  • Sxx1 Position Measurement. Oxx3 measured position (was located by): S15 Observable Entity

HW: MD, GH (& TV to revise). The definitions should feed into the issue for the diagrams & text descriptions of Position Measurement.

Dear all,

In issue 388 ( we agreed the properties for position measurement. This issue 611 ( is about creating their scope notes and examples. Athina, Gerald, Martin and I have drafted these as shown below. Please consider them and we can discuss at the next SIG meeting. The examples for S23 at the bottom are included to correspond with the ones for the properties.

All the best,
