Regarding "Actuation" and "Actuator" conceptual models for IoT and its mapping to SOSA

Dear all:

Currently, I'm working on the "*BCI Ontology*" [1], an ontology for
Brain-Computer Interaction activities, which is aligned to SSN.
We are expanding its domain to include the conceptual models for
*Actuation* and
*Actuator*.
We are following closely the effort done by the IoT community: "*IoT-O*"
[2],[3].

As described in section 3 of [2], the authors introduced an ontology for
actuators, called SAN [4]. The authors proposed the *Action-Actuator-Effect*
(AAE) design pattern, inspired from the SSO design pattern (SSN). Figure 2
of [2] depicts the proposed structure for AAE inspired on SSO.

I was wondering how SOSA [5] has defined the structure for the
correspondent AAE design pattern defined for the IoT domain:
- Has SOSA defined its own design pattern for Actuation and Actuator
conceptual models (similar to AAE)?
- Has SOSA considered the proposed SAN ontology from the IoT community?
- If so, how does SOSA map to SAN (and, therefore, to the proposed AAE
design pattern)?

Thank you very much for your feedback.
