Observation Reorganization -- S4 Single Observation
We start introducing a new generalization of the former S4 Observation for observing observable situations as S27 Observation, taking over the scope note of S4. We redefine S4 as S4 Single Observation, so that the current properties of S4 stay valid under S4, but as a special one-proposition case of S27 Observation. We connect S27 Observation directly to CRMinf, I1 Argumentation, and no more to E13 Attribute Assignment

In the 60th joint meeting of the CIDOC CRM and ISO/TC46/SC4/WG9 & 53rd FRBR/LRMoo SIG, the group reviewed the HW by MD & PF on the reorganization of CRMsci Observation (it being recast as a Single Observation). The details of the proposal, some discussion points, and the definitions of the relevant set of classes/properties can be found in the attached document.
Decisions:
The SIG approved:
- the new definition of S4 Single Observation,
- the redrafting of the properties O8, O9, O16,
- the introduction of the new property O37,
- the introduction of the new class S29, and
- the introduction of the property O38.
N.b.: the labels pertaining to S29 and O37 are up for debate.
The scope note of S29 has been flagged for further elaboration.
HW: MD, PF, GB.
Bern, April 2025
In the 61st joint meeting of the CIDOC CRM and ISO/TC46/SC4/WG9 & 54th FRBR/LRMoo SIG, the SIG reviewed the proposal by PF to add a clause (underscore) in the scope note of S29 Observable Proposition, to increase its legibility.
- This class comprises proposition sets containing exactly one binary proposition which is or could, in principle be, encoded in a knowledge representation language, and which characterizes an observable phenomenon, regardless of whether it has happened or not. For example, it could refer to the intended meaning of a text about an observable phenomenon, the belief value concerning its reality has not been asserted, or to the question if a certain situation has ever happened. The identity of an instance of S29 Observable Proposition is given by the total of its content, regardless of equivalent encodings.
The class S29 Observable Proposition plays the role of an important logical interface between observing single propositions or more generally observable situations. It is particularly relevant for implementing effective queries. For documentation, the use of the simpler shortcut properties of S4 Single Observation, i.e. O35 observed entity (was observed by), O9 observed property type (property type was observed by) and O16 observed value (value was observed by) will, typically, be the preferred approach.
Decision: the proposal was approved. PR volunteered to proofread it. It will appear (edited), in the next version of CRMsci.
