Dear all,

Here is our homework for Issue 645:

It is more a brainstorming/discussion by Martin and me on the relevant aspects. 

Your feedback/comments are more than welcome!

Best regards,

In the 57th CIDOC CRM & 50th FRBR/LRMoo SIG Meeting, MD presented HW: various scenarios of someone adopting a belief (fully, partially, or not at all) as a trust on the source of the belief in question.


  • Widen the meaning of I7 Belief Adoption to include rejecting a belief (in the sense that it is a negative adoption of a belief), or modifying it (hence adopting it partially).
  • Additional property necessary for the adopted the belief (for the degree of adoption).

Discussion points:

  • Is “unknown” really a rejection of the original belief?


HW: PF to rewrite the scope note for I7 Belief Adoption and to draft the scope note for the property that assigns a degree of adoption.
