Project Scope “This implementation guide will explore the Service-Aware Interoperability Framework (SAIF) methodology to show how various HL7, IHE and OMG immunization-related artifacts can be deployed to satisfy immunization interoperability use cases. “

January – May 2012 Determined approach  What artifacts to use  What form the document takes “ Venn Diagrams” – overlap among artifacts  Mapped relevant artefacts to outline section  Documented artefact spec documents Recruit case studies Vet work so far Determined similarities with Semantic Health Net project

Common Information Model Approach  Monitor and build off CCDA  Start with V2-CCDA and V2-IC comparison  Add EHR FIM information model, IZ DAM, vMR Template challenges

CDS Arden, GELLO  Collect existing examples Arden Translate RulesSpeak into Arden GELLO IG for vMR  Extract sample rules from CDC project, implement  Determine fit of Arden and GELLO into DSS and overall architecture

SAIF Arch Prog Notes Is FHIR intended to serve as a Common Information Model in a SOA/SAIF contest to which multiple other HL7 and non-HL7 artifacts can be mapped?  Yes  Devil is in the details Look at the conformance statements in SAIF CD  These are aimed at what the SAIF implementation guide should do, not something following the SAIF IG

13. © 2010 Health Level Seven ® International. All Rights Reserved. HL7 and Health Level Seven are registered trademarks of Health Level Seven International. Reg. U.S. TM Office. Some Ideas Look at the conformance statements in SAIF CD Create a mapping including FHIR and including Rob S’s list of data elements and mapping other artifacts into it. I.e. map everything to FHIR common data model. Examine “use case“ artifacts to see what use cases can be implemented within the scope of the project Revisit IXS, RLUS and DSS. Make list of needed PSMs. Map services to PSMs Should lend itself to a tool Be part of MnM BOF for EA – see Patrick Be part of Out of cycle meeting to work on artifacts for SAIF IG - TBD

SOA Ideas Can break into 2 parts,  high level – scoping, approach, requirements  Technical framework – SAIF IG Avoid dependencies on unfinished specs Context in services is established thru service contract (in layers)

What the project is A roadmap to establishing interoperability among a multiplicity of systems speaking different (immunization) standards Lends itself to tooling Provide a standards guide that addresses multiple “hops” in the communication path Be implementable and testable Allows domain experts to trace use cases to implementation

What the project is not Does not change existing specs Does not recommend one spec over another Exception: may change or recommend service tech specs  S&I does gap analysis  Prefer not to recommend

Fri Q1 ideas Project Scope – “explore” vs “show” also remove “methodology” JD will assist organizing next OMG tech mtg  A way to gain visibility to OMG working drafts  New mechanism for HL7 members – research Include webexes at OMG, HL7 and IHE  SAIF Arch Prog Out-of-cycle  Coordinate with S&I Framework Make community initiative, not PH – Ken  Coordinate with Aus PCEHR project Roles and control

Fri Q1 ideas cont hDATA may provide data model  Talk to Gerry and Lloyd The issue of synchronous vs. asynchronous transactions is out of scope and implementation decision Clearly state that the expected result is to add PSMs to existing tech specs and tweak tech specs What formalism? SoaML? SOA ref arch framework?
