IHE Technical Frameworks
Technical frameworks are published in volumes. The first volume typically defines the Profile, the use cases, the actors involved and the requirements for conformance. Subsequent volume(s) specify how to implement the transactions used in the Profiles. The last volume is usually reserved for National / Regional extensions.
