DIRECT Transport Specification Templates

The constraints applied to specific data elements in the transport metadata is set by the originating systems and intended to be used by the recipient system or systems. For transport specification profiles, similar to CDA implementation guides, a template is a collection of related constraints. For validation/testing purposes identifying each constraint and organizing them into templates is very useful. This IG is using a consistent approach across all three documents: CDA, Exchange, and Direct..

Originator Responsibilities

Based on the applicable local policies, the originator will apply the appropriate privacy annotations and set the author and intended recipient information, if needed.

Recipient Responsibilities

The recipient system is expected to process and persist the metadata along with documents to which its applies. While the template identifiers will not appear in the metadata, they may be used for testing/validation as a convenient grouping of related constraints.
