Transactions/Queries Required for DAF Find Document(s) based on Patient Identifiers
Find Document(s) based on Patient Demographics *
Get Document(s) based on Document IdentifiersGet Document(s) based on Patient Identifiers
Get Document(s) based on Patient Demographics *
Get Document(s) for Multiple Patients based on Patient Ids **
Supply and Consume User Assertions

Find Patient Identifiers based on Patient Demographics
Find Patient Demographics based on Patient Id
* - Not supported in a single query in SOAP (Can be executed as a combination of 2 or 3 queries)** - Not supported in IHE RESTful stack in a single query
Decision: Leverage work from Direct SWG for the single query as it gets completed.
• Finalize Queries to be supported
9
DAF Candidate Standards Analysis CONTINUED
• Finalize Behavior Models to be supported
– Synchronous Request/Response ?
– Asynchronous Request/Response ?
– Decision: Include both in the Initial IG
10
DAF Candidate Standards Analysis CONTINUED
• Finalize Differences between Local and Targeted
– Should we adopt common standards for both Local and Targeted where feasible ?
• E.g XDS vs XCA• E.g PDQv3 vs XCPD
– Decision: Use the XCA/XCPD versions since many of the queries are going to cross affinity domains and the standards will support both LDAF and TDAF
