Published: 2016-08-10

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

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

General

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

REST behavior

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

Security:

Data Sources are advised to implement security requirements according to their existing protocols for data extraction purposes. However Data Sources implementing DAF-Core IG can reuse their security protocols for data extraction purposes as applicable.

RESTful Operations Summary

Resource(Profile Name)	Search	Read	Version Read	Instance History	Create	Update
DAF-Task	SHALL	SHALL	SHALL	SHALL	SHALL	SHALL
DAF-Core profiles	SHALL	SHALL	SHOULD	SHOULD	MAY	MAY

Data Source Search Parameters

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

• _id
• _lastUpdated
• _profile
• _count
• _include

Data Sources SHALL support the following search contexts defined within the FHIRspecification.

• Search context by specifying a particular resource type

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

Resource Name	Search and Include Parameters
DAF-Task	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-Core profiles	Search parameters provided by the DAF-Core IG

DAF-Research Specific Operations

Data Sources SHALL support Patient/$everything operation using the DAF-Core profiles.

Data Sources SHALL support daf-extract-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.
