Functional roles reflect functional aspects of relationships between entities. Functional roles are bound to the realization/performance of acts, where actions might be concatenated to an activity or even to a process. [ISO 22600-2] Functional Roles can be grouped according to their authorization to access Protected Information and perform various operations on protected information. For example, a healthcare provider in Organization A is authorized to access Protected Information from Organization B (when Organization A and B have entered into a trusted relationship) if that provider is associated with the Functional Group whose permissions grant access per that Functional Role. In summary, the functional role defines the access control decision. A functional role is bound to a policy. [HL7 DAM]
