Actor Mapping to Interoperability Specification

This section provides implementation recommendations for actors and services involved in the CA:FeX transactions. The Interoperability Recommendations tables outline how system actors (e.g., Data Consumer, Data Responder) participate in supported services and the technical profiles or transactions that enable those interactions.

These tables serve as a tabular representation of the corresponding sequence diagrams and include added details to support implementers in understanding integration points, profiles, and service patterns within their implementation context.

Each table is based on the corresponding use case flow diagrams and sequence diagrams presented in this guide:

Use Cases illustrate the clinical context and information flow.
Sequence Diagrams translate that flow into technical interactions.
Interoperability Recommendations Tables summarize the technical roles, services, and applicable profiles or transactions described in those diagrams.

Each row represents a specific actor (e.g., Data Consumer, Data Responder) and outlines:

The service(s) they support in each use case
The technical actor role they play
The profile or standard used (e.g., CA:FeX, PDQm, PMIR)
Where applicable, the interoperability transaction or capability that supports the service

The Implementation Expectation column uses the terms:

Expected
Represents interactions or services that are expected to be part of CA:FeX-aligned workflows. These steps reflect baseline implementation patterns but are not prescriptive or enforced as strict requirements.
Optional
Represents interactions or services that may be implemented depending on jurisdictional policies, system capabilities, or implementation context. These steps support flexibility within CA:FeX workflows but are not universally expected.
