Siemens Presentation(30 minutes)

Alex DeJong from Siemens presented their vision for SOA. This presentation included a review of the basics of SOA.

It includes services, messages, and events. Nancy is trying to push standardized methodologies. Question/Action:

  • ? Has Siemens considered mapping the care functions to the EHR-S
  • We will need to publish the 'how to' for infrastructure contracts. Ed Larsen will provide an example of DIRSA agreement.
  • We should produce design heuristics for the level of granularity required.

Alex presented a list of questions:

  • What can we do to make it simpler to absorb and productively the standards?
  • Message-, document- and/or service based
    • Should document have actions associated with them beyond storage? If so, how is this different from a message?
    • The place of an "Event" in SOA.
    • How is an event a message, how does it differ?
    • Rich vs 'light' events
    • Examples of SOA vs messages
    • exception handling and other cross-cutting concerns such as security, vocabulary/terminology, history, versioning, etc?
  • How do the HL7 SOA workgroup and ArB SOA efforst align and/or compliment each other?

Dynamic Framework (45 minutes)

Taxonomy of Services (3 hours)

Why a taxonomy?

  • What kinds of things?
  • What are the inter-relationships?
  • Ontology of relationships
CategoryAtomicState change
CapabilityTT
CoreTF
ProcessFF


Taxonomy? Diagram

Taxonomy:

  • simple hierachy, e.g. race/ethnicity
  • classification faced on one facet
  • not an assembly

thesaurus has relationships


There is an OWL ontology in the Federal Health Architecture for services. (See formal definitions slide "New Data Reference model 2.0)

What facets are usefull?

EARL classification system.

Discussion

Harmonization

Wednesday 1300 - 1700

Pm Discussions

AMS wants the HL7 SOA metamodel to describe all of the artifacts to describe services, described in UML and RM-ODP.

Input from XA, DOD, NCI, UPMS will be used to determine what UML needs to have added, or constrainted? Drive off of UML to have tools to enable the SOA.

We can use a subset of RM-ODP meta-model.

HL7 ARB is not the only interested party. SOA-Pro group submitted an RFP to OMG. The work product will be in 'final submission' stage on August 25, 2008. This is the OMG Software Services Profile and Metamodel RFP, which attempts to describe the serviced metamodel. Created by convergence between SOA-Pro and UPMS.SOAUPMS.zip

OHT Modeling project for HL7 - Lessons Learned (Rogers) (60 minutes)

Moved to Tuesday after lunch

2 hours - Meta Model Review, UPMS Profile (2 hours )

Slack time (60 minutes)
