Agenda

HSSP Alignment Behavioural Framework Service Classifications

HSSP Alignment

• • Three Areas that need discussing
  • Artifact Alignment
  • Process Alignment
  • Relationship with OMG

• Artifact alignment: Aligns with HSSP service functional model.
  • The HSSP Service Specification Framework
    • Should be called out in the SAEAF as relevant material and referenced
      • Minus the “requirements” that the Logical and Platform Models happen outside of HL7
      • Functional and Semantic Profiles are relevant
      • Both have a loose coupling with Information Models
    • Both the SAEAF and the HSSP Process support MDA, Constraint Patterns.

Cecil - We need to reach out to the DSS group. They are the closest ones to implementing what we have defined. John - Agree: needed to verify the SAEAF.

• The HSSP Process provides one means of intersection between HL7 and OMG
  • Other Intersections include the Standards MDA, SOA ML, UML, BPDM
  • The HSSP Process is encouraged and Facilitated by greater specification on the HL7 side
    • The relationship with OMG is not only considered important, but crucial
    • However, the HSSP process is not the only means of creating constrained specifications based on the SAEAF’s Analysis Specification
  • OMG wants to encourage this relationship

Charlie, Cecil, and others will massage the motion during the break.

Motion:	Moved-Second	Vote
As a result of discussions with HSSP representatives, the ArB affirms that the HSSP framework is in conceptual alignment with the HL7 SAEAF with respect to both processes and artifacts. In particular, the MDA-based process, i.e., the HSSP Service Specification Framework, produces a Service Functional Model, a Platform-Independent Model, and a Platform-Specific model that are, in principle, in alignment with the HL7 SAEAF. However, it needs to be made clear that this alignment is between the overarching HSSP process/artifacts -- which by definition include at least two participating organizations (e.g., HL7 and OMG) -- and HL7 as the sole producer of SAEAF-compliant processes/artifacts. This is an important distinction because it will almost certainly be the case that the SAEAF framework will result in processes/artifacts produced completely within HL7 which are not necessarily defined in the HSSP, thereby resulting in some degree of non-alignment. As the SAEAF artifacts and processes mature, it remains an open question as to how (or if) any variations between the SAEAF and the HSSP will be addressed.	7-0-2

Walkthrough of SAEAF

Alan presented a walkthrough of the SAEAF document.

There was significant discussion of the alignment between the SAEAF, the RIM, and the BRIDG model.

There has been a lot of discussion as to how HL7 intersects with other groups and standards.

Governments are also interested, as is W3C. Specifically with imbeded objects, in reference to how DICOM handles imbeded objects.

Send any topics to Charlie Mead in the next nine hours.

The meeting was adjourned at 2:50pm US EDT.
