MnM Project On Defining SAIF Artifacts

Discussion Notes from MnM Conference Call on August 27, 2010

Artifact Definitions

Ultimately need MIF-definitions for new and modifications to existing definitions to align with SAIF

Artifacts of Interest

At SAIF Levels:

• CIM (Computationally Independent)
• PIM (Platform Independent) - Where M&M has its primary responsibility
• PSM (Platform specific) -

Observations

• Question: At what level does target paradigm (messages/documents/services) become critical?

  Suggest the CIM can be agnostic and the PSM MUST know its target.

  Indicates that distinctions begin to appear at PIM level (perhaps as sets of patterns)

• Question: - what is a platform?

  XML schemas, java objects,

  (services/documents/messages are a different dimension, not platforms)

• Objective: Allow HL7 to defer the paradigm representation as DEEP Iin the SAIF hierarchy) as possible for maximum re-use.

Scope of Project

Develop Artifact Definitions that satisfy all three levels, starting with what we know best. Candidates:

• Static Models
• DAMs
• Shared models (and consistency of Use)
• Begin chewing on Interactions

  (particularly as they do or do not reflect our current practice)

  (and as they apply to the "document" paradigm).
