Agenda:

1. Administrative (max 30 minutes)
   • Agenda Review/Additions/Changes (max 5 minutes)
   • Approval of the Minutes of the previous meeting in Cambridge: (max 5 minutes)
   • Announcements (max 10 minutes)
   • Report from the HL7 Cambridge WGM, and the meeting in Cambridge (Rene, max 15 minutes)
     • Amnon Shabo was elected co-chair in Cambridge. He represents the vendor community and has specific knowledge about the use of native XML databases in combination with RIMBAA.
     • The Services for RIMBAA project was revived (Ann will report in more detail during this meeting)
     • Alexander Henket held a presentation about the use of (abstract) Schematron to validate data type requirements
     • There were a number of presentations about architectural principles when it comes to the design of v3 based services. Jean Duteau and/or Lorraine will elaborate on some of these aspects during this meeting.
     • SMIRFS, a particular way of chunking object nets, was discussed again. Rene will present the state of things during this meeting.
     • New & active implementers are being sought to jointly create JavaSIG2010, an upodated version of the Java SIG toolkit.
   • Planning of next meeting in Sydney
   • Approval of the Software Implementation of CDA whitepaper; which was created as part of our project to create a series of whitepapers.
2. User Interface (UI) based on the RIM; binding UI to the RIM. See User Interface for RIMBAA Applications for generic information on RIM-based UI design.
   • Tim Chearman (NHS UK, CUI project lead), on the NHS Comon User Interface (CUI) project.
     • The NHS, jointly with a university are developing an Opensource framework. See [1] for details.
   • Michael van der Zel (University Hospital Groningen, NL), on their developments related to the use of Forms (Infopath) and User Interfaces (CUI Toolkit/ASP.NET & Silverlight) bound to HL7 v3.
3. Development of a new RIMBAA application (Andy Harris)
   • Update on his efforts to create a new RIMBAA application for NIHR (UK). Andy has ample experience with RIMBAA applications and recently started the development of an entirely new application.
4. MDA based on DCMs (Michael van der Zel, University Hospital Groningen, NL)
   • Practical experiences of a Model Driven Architecture (MDA), based on DCMs (ISO Templates). The architecture is fully model driven, inclusive of the database model. Micheal will also discuss the extensive role of terminology in this project.
5. Request/response services for certain DCMs/Templates (Ann Wrightson)
   • Experience with a toolkit to build request/response services on a patient's record that are expressed as a request for available instances of certain DCMs/Templates. There is a service-in-the-making that works like that within the NHS Wales SOA (using "record elements" based on the Scottish data component standards in the absence of an available/adoptable RIM-based DCM repertoire).
6. Services for RIMBAA Project (Ann Wrightson)
   • Status report and overview of the "Services for RIMBAA" project
7. Information Decomposition at NCI (Jean-Henri Duteau and/or Lorraine Constable)
   • The NCI project uses v3 based services. Jean will explain the design and methodology principles of its architecture team when it comes to the design and composition of services, and achieving the right balance between the richness of the information model and the specificity of the service operation.
8. The state of the SMIRF (Rene Spronk)
   • SMIRFs (as an acronym) have been introduced in Cambridge. Rene will provide an overview of the state of the discussion.
9. Suggested new discussion items by John Koisch (received by e-mail)
   1. SOAP / REST – It is pretty clear that we can interchange these in an implementation by shifting around the granularity of the calling operation. However, I would think for HL7, providing some sort of explicit implementation boundaries is going to be necessary if we want to be sure that one or the other does not lead to implementations that violate the spirit / letter of what HL7 is about
   2. The Behavioral Framework for SAIF provides the place for implementers to make clear statements about a message’s provenance. I think that RIMBAA is a good place to bring in work from OpenProvenance and the like.
   3. Service Impl stubs .... I think that sample implementation stubs are as important as sample messages in implementing a specification. This is something that RIMBAA is positioned to be involved in, I think
   4. HL7 extensions to WSDL ... The WSDL specification from w3c allows for certain extensions. I think that providing a set of HL7 extensions (for example, a set of provenance statements about the information expressed at an interface) would be a really good way to make HL7 more flexible and clear in implementation.
10. Discussion of RIMBAA Issues
