The Knowledge and Vocabulary Service Collaboration provides the ability to retrieve medical knowledge and terminology. This Service Collaboration utilizes:
HITSP/T81 Retrieval of Medical Knowledge which enables the request and receipt of additional knowledge about a medical concept based on specific context parameters. This Transaction does not prescribe the knowledge content of the message returned but provides the specifications for the query and receipt of additional knowledge
HITSP/T66 Retrieve Value Set which enables the request and receipt of value set with the appropriate terminology or code system and a value set with an appropriate map from one terminology to another
For more information about the underlying capabilities, pre-conditions, post-conditions, data flows and other detailed information, please refer to the constructs that are used by this Service Collaboration.
The Service Collaboration document illustrates one internal view diagram and sequence table for each service interface. The diagrams are descriptive and the sequences are not mandatory. They may be affected by policy, chosen architecture, and implementation details. Conformance is measured against the underlying constructs.
