• Announcement of European meeting, see Agenda for Amsterdam RIMBAA meeting Oct. 27th
  • Motion to designate the Oct. 27th meeting in Amsterdam as an out-of-cycle meeting of the RIMBAA WG (Andy/Peter, 6-0-0).
  • Action item for Rene: notify HL7 HQ of this decision.(done, 20090921)
• Discussion of the goals of the RIMBAA WG:
  1. Marketing - Public exposure of successes (of v3 implementability and the RIM itself)
  2. Sharing of experiences and solutions
     • Document/describe (for all possible cell transitions) how those steps could be supported/achieved.
     • We focus on Patterns for Application Development. Guidance, no normative outcomes.
     • Reference Implementation (Java SIG materials, extend OHT?)
     • Outreach to RIMBAA implementers (especially those not present at RIMBAA meetings); publish reviews of existing RIMBAA implementations
  3. Education - for newbies to RIMBAA
  4. Standard Improvement
     • Identify issues in HL7 standards during the implementation process
     • Work with ITS WG on an RS XML ITS and the identification of CS-RS transition issues
     • Identify issues caused by the ‘interoperability mindset’ of the RIM
     • V3 constructs: Context Conduction, Update Mode, Object Versioning
     • Work on SAEAF
• Discussion of the RIMBAA delivarables. Motion to approve the following two projects (Andy/Peter, 6-0-0)
  1. A set of harmonized whitepapers that detail the things one needs to be aware about when creating a RIMBAA implementation. Initial whitepaper: "ORM Approaches".
  2. Reference Implementation(s). Documentation of the reference implementation and the design process associated with these applications.
• Action item for Peter/Rene: create project statements for these projects and bring those to the steering division for approval.
• Motion to adjourn (Peter/Amnon, 6-0-0) at 17:07

Minutes of Tuesday Q4

• Attendees:
  • Peter Hendler, KP (co-chair)
  • Andy Stechishin, GPi
  • Rene Spronk, Ringholm (co-chair, scribe)
  • Nick Radov, Axolotl
  • Davide Magni, ITAL TBS

  • Ravi Natarajan, NHS
• Rene calls the meeting to order at 15:33
• Rene/Peter briefly present the RIMBAA technology matrix.
• Tool Presentation by Dave Carlson and John Timm.
  • Primary aim of the tool was to do (CDA-) model refinement in UML, serialize in schema, or back-out and generate MIF (required for publishing).
    • Templates can't yet be transformed back to MIF. Rik Smithies notes that templates can be expressed as RIM models and hence as MIF. Lots of template-discussions are still ongoing, there is no single way of expressing templates at this point in time.
  • Model driven framework for generating run time API, with clone names, with one or more templates validated, consume XML instances that deserialize into appropriate template.
  • UML-OCL template model (by standards creator, expressed as a UML Profile, annotations in EMF to express OCL constraints), transform to code generation model (EMF), code generation to create Runtime API in Java (inclusive of the OCL constraints), produce/consume/validate CDA instances.
  • Template model: is-a and has-a relationships between templates, given that one template (LIM, e.g. specialization of an IHE template) is a specialization of another template (LIM, e.g. IHE template) is a specialization of a RIM-derived model (CIM). Requires manual work to determine specialization hierarchy (based on textual requirements in CDA implementation guides)
  • John: generalizing this to all CIMs (not just the CDA model) is definitely possible. Requires additional work on the MIF to Ecore transformation code.
  • Link to the software: mdht.projects.openhealthtools.org, the presentation is available at https://mdht.projects.openhealthtools.org/files/documents/58/217/CDA_Tools_Overview_HL7.ppt
• Tool Presentation by Robert Worden presents a mapping tool; in preparation we asked him to focus on mapping of a proprietary database model to an RMIM.
  • Robert present why we need mapping at all. Mapping is easier than migrating. Publishing shareable [i.e. not hardcoded] mappings (e.g. v2-v3) is a good idea and drives adoption of v3.
  • Most mapping issues are related to the mapping of non-leaf concepts in XML. Map structure A to a semantic model, map B to the same model. Use an R-MIM format (MIF transformed to EMF) as the underlying semantic model.
  • The tool ultimately generates transformation classes (or XSLT).
    • Andrea: ItalTBS adds validation to these classes.
  • Robert demoes a mapping from a proprietary database structure to a CMET. Robert has no EMF for 'the RIM', only for R-MIMs. Would lead to a different type of mapping.
  • Tool can be found at: HL7 Homebase; Presentation Slides
• Announcements
  1. out-of-cycle in Amsterdam on Oct.27 2009,
  2. request for speakers in Phoenix,
  3. announcement of joint meeting with ITS WG in Phoenix
• Motion to adjourn (Peter/Andy) at 16:59
