take a call, hang up and dial in again when finished with your other call– Hold = Elevator Music = very frustrated speakers and

participants

speaking

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
