Rationale: Device is the most appropriate resource to represent any sort of automated system performing or participating in activities.  Device implements the Participant pattern, and is listed as an actor in the Event pattern and a performer in the Request pattern. Some workgroups (incl PatientCare) have already updated their resources to allow references to Device in places when recording participants.  We suggest that each WG review their references and ensure that Device is listed as an allowed participant type if appropriate.   We will update the Practitioner resource "Boundaries and Relationships" section to clarify this position (change highlighted in bold): Boundaries and Relationships ... Practitioners are also often grouped into  CareTeams  independently of roles, where the CareTeam defines what specific role that they are fulfilling within the team, and might or might not have actual practitioner role resources created for the practitioner (and in the care team context, the organization the practitioner is representing) When an autonomous system or machine is an actor or participant, the Device resource should be used to represent that system.  This would include artificial intelligence or machine learning (AI/ML) systems, as well as other automated systems.
