CapabilityStatement Resource

The CapabilityStatement resource for the Document Consumer is MHD Document Consumer.

Security Consideration

TLS SHALL be used. This national extension enforces authentication and authorization of access to the Document Responder using the IUA profile with extended access token. Consequently the Retrieve Document [ITI-68] request must authorize using the [ITI-72] transaction of the IUA profile.

The traceparent header is required, as described in Trace Context header.

Security Audit Considerations

Document Consumer Audit

The Document Consumer shall be able to record a Retrieve Document Consumer Audit Event Log. Audit Example for a Retrieve Document transaction from consumer perspective.

Document Responder Audit

The Document Responder shall be able to record a Retrieve Document Responder Audit Event Log. Audit Example for a Find Document Lists Transaction from responder perspective.
