==Agenda of Tuesday Q4 [[Image:Technical med.gif]]==
+
[[category:RIMBAA Minutes]]
−
'''Meeting Room: Atlanta 1'''
 
−
*'''Processing/validating RIM Based Models.''' (max. 45 minutes) One of the main problems to tackle, whether for messaging/documents or in memory objects structures in RIMBAA, is the testing of validity of constraint models, which includes evrything from a CIM, a LIM or a DCM, with GELLO/OCL. In a RIMBAA environment one would normally do code generation from the MIF/EMF to tackle this.
 
−
**Presentation of an [[EMF]] driven Template/OCL code generator by Dave Carlson and John Timm (IBM Research)
 
−
***The tool has the prime intent to facilitate the use of CDA templates. It is part of the OHT efforts on the Eclipse platform. Focus of the RIMBAA presentation will be on the code generation aspect.
 
−
***It will show the use of EMF code generation with OCL constraints, from UML models.  Although the example models are CDA restrictions, most of the principles should apply to RIM restriction also. They are very interested in generalizing their approach for RIM and v3 messages, and also for [[DCM]].
 
−
***A longer presentation of the tool will be held in a meeting of the Structured Documents WG on Monday Q3, and the Tooling WG during Tuesday Q2.
 
−
*'''Mapping data in legacy databases to RIM Based Models''' (max. 45 minutes). Given the amount of legacy databases a way has to be found to encapsulate those datbases in a layer which provides the programmer with a virtual RIM based API - inclusive of object based querying using RIM terms.
 
−
**Presentation by Robert Worden about a semantic mapping tool he's been working on. Focus of the presentation will be om the mapping between legacy ER databases and RIM Based models.
 
−
***The tool is primarily oriented towards message mappings (the AO-CS, and AO-CP and AS-CO cell-transitions in the technology matrix); it can however also be used to map legacy database structures to RIM based models (AP to CO/RO mapping).
 
−
*RIMBAA Issues/talking points
 
−
** Report from ITS WG on a [[RIM based ITS]], and on the [[New ITS]].
 
−
** Issues on Wiki: [[:Category:RIMBAA Issue]]
 
−
* Discuss impact of proposed RIM changes to RIMBAA, e.g. negationInd, datatypes R2
 
−
 
 
−
==Tuesday Q6 (19:00-21:00) [[Image:Technical med.gif]]==
 
−
*Tooling demonstration (hosted by the tooling committee)
 
−
**With a slot for a presentation on RIMBAA tooling (no opportunity for discussions)
 
−
**ItalTBS (Andrea Ceiner et.al.) will present new features of their toolkit

**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: [http://mdht.projects.openhealthtools.org mdht.projects.openhealthtools.org], the presentation is available at [https://mdht.projects.openhealthtools.org/files/documents/58/217/CDA_Tools_Overview_HL7.ppt 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.

  • 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.
