Query Network

Community of participants that agree to interact with each other. There will be

many networks; requestors and responders may participate in multiple

networks.

Query

Query Lifecycle1. Requestor optionally uses a composer

to create a query and submits it to their dedicated agent.

2. Agent submits the query over the Internet to each participating responder’s gateway and awaits responses.

3. At each participating responder, the standard gateway passes the request to a site-specific adapter.

4. The adapter calculates site results for their site and returns them to the gateway.

5. The gateway returns site results to the appropriate agent.

6. The agent returns site results to the aggregator that combines site results into combined results

7. The aggregator makes interim and final results available to the requestor.

Query Health supports multiple “query types” traveling over the same transport and envelope

Types are identified by a name and version– E.g., “MU Stage 1 EP/1.0”

Each type implies– Query syntax– Clinical information model– Response format
