Published: 2016-08-10

Published by: U.S. Office of the National Coordinator (ONC)

This profile defines the expected capabilities of the Research Query Responder actor when conforming to the DAF-Research IG. The statement includes the complete list of actual profiles, RESTful operations, search parameters supported by a Research Query Responder.

General

FHIR Version:	$ver$
Supported formats:	json and xml

REST behavior

The Research Query Responder SHALL implement REST behavior according to the FHIR specification. The Research Query Responder SHALL use either DAF-Core or DAF-Research profiles as needed to create query results. The Research Query Responder SHALL support both json and xml resource formats for all DAF interactions. The Research Query Responder SHALL identify the DAF profile(s) supported as part of the FHIR BaseResource.Meta.profile attribute for each instance. The Research Query Responder SHALL declare a Conformance statement and identify the list of profiles, operations, search parameters supported.

Security:

Research Query Responder are advised to implement security requirements according to their existing protocols for query execution and returning results. However Research Query Responders implementing DAF-Core IG can reuse their security protocols for data translation and loading purposes as applicable.

Research Query Responder Search Parameters

Research Query Responder SHALL support the following common parameters as part of queries related to DAF-Research profiles:

• _id
• _lastUpdated
• _profile
• _count
• _include

Research Query Responders SHALL support the following search contexts defined within the FHIRspecification.

• Search context by specifying a particular resource type

Research Query Responders SHALL support Modifiers as applicable to the data types of the search parameters. Research Query Responders SHALL also support Composite Search Parameters as defined in the FHIR specification.

Resource Name	Search and Include Parameters
DAF-Task	id - Search based on resource id ( string) identifier - Search based on Task identifier ( token) code - Search based on Task code ( token) status - Search based on Task status ( token) parent - Search based on Task parent ( reference) owner - Search based on Task parent ( reference) performer - Search based on Task parent ( reference) requester - Search based on Task parent ( reference)
DAF-Provenance	target - Search based on Provenance target ( reference) start - Search based on Provenance start time ( date) end - Search based on Provenance end time ( date)

DAF-Research Specific Operations

Data Marts SHALL support daf-execute-query operation on the ROOT URL of the system.

Data Marts SHALL publish their Conformance statement using the DAF-Conformance profile and identify the specific operations supported.
