Data Access Framework (DAF) Technical Work Group

March 5th 2014


DAF Technical Work Group (Scope)

In Scope:

  • Leverage the IHE White Paper developed by IHE PCC outlining existing IHE profiles and their applicability to DAF

  • Identify additional standards/profiles that can be leveraged to meet the DAF (LDAF and Targeted) query use cases with a focus on modularity and substitutability

  • Identify the gaps in the existing standards/profiles to meet the use cases and requirements outlined

  • Development of implementation guides/API’s required for implementation of the use cases

  • Support DAF Pilot activities

    Out of Scope:

  • Creation of policies to enable queries

    • Policies include consent, patient matching, disclosure requirements etc.

  • Identifying business processes and workflows required to enable queries.

Implementation (S&I Community)

TWG #1: Document Metadata based access for LDAF & TDAF

Candidate Standards Analysis

Finalize Actors + Transactions + Technology Stacks and Standards

Create IG’s based on existing standards

Create SWG to modify/add standards as necessary

Update IG’s based on SWG output

Implementation (S&I Community)

TWG #2: Data Element based access for LDAF & TDAF

Candidate Standards Analysis

Finalize Actors + Transactions + Technology Stacks and Standards

Signifies milestone or deliverable

Create SWG to profile standards for data element access


DAF Abstract Model


DAF Queries for Document Metadata Based Access


Document Metadata based DAF Queries to IHE Profiles Mapping (Initial Version)


Document Metadata based DAF Queries – Other Candidate Standards

Transport ?

Security ?

Content (Query Structure and Query Response Structure) ?

Vocabularies ?


DAF Queries – Next Steps

  • Analyze any other potential candidate standards and their maturity for DAF Document Metadata based access

  • Start identifying granular parts of the IHE profiles that would be required for DAF purposes

    • Actual Transport/Security aspects

    • Queries to support

    • Optionality that needs to be removed

    • Result structure for documents
