March 30 Agenda (10:00-17:00)

  1. Administrative (max 30 minutes)
  2. Use of a SMIRF like approach (Dale Nelson, max 20 minutes)
    • Dale was involved (some year ago) in a project which used CMET-like models as the basis for data exchange and persistence. He will show the highlights of its architecture and will share best practices.
  3. Implementation aspects of the caEHR project at NCI (topic confirmed)
    • The caEHR project is based on HL7 v3 services.
  4. Experiences with using the RIM to enable agile architecture - start developing and capturing data while use cases are forming (George de la Torre, max 45 minutes).
    • George has been developing clinical based applications based on RIM Java objects for the past 6 years. Examples include: Proteomics experiments/robotics, Public Health immunization registries, Genomics EDC application, Clinical Repository and recently a Clinical Trials Scheduling system for the Harvard Medical School (HMS).
    • He will focus on how the RIM enables agile architecture, that is, how one can start developing and capturing data while use cases are forming. The HMS case study is a great example..
  5. Report on a HL7 v3 services based project (Dale Nelson, max 20 minutes)
    • Dale was involved in a project that uses a RIM based services layer. Dale will discuss the choices that were made when creating the service inventory, as well as the design of the v3 static models used as service payloads.
  6. The use of run-time metamodel registries
    • Ontology of models, ontology of uses, packages of models (e.g. a set of models used for a particular purpose), linkages between models, SNOMED subsets, language translation of models.
    • The NCI project defines such a repository as part of its Semantic Infrastructe work.
  7. Report on v3 implementation at Intermountain (Stan Huff, to be confirmed)
  8. An approach to WSDL generation, and how to associate them with RMIMs. (Lorraine/Jean/John K.)
    • This approach is also used at NCI.
    • Services have a 'payload' R-MIMs; with context (e.g. author, patient) removed; the context shows up as a service parameter. The service 'payload' may consist of a simple II data type instance.
  9. Persistence Models versus Interoperability Models
    • See wiki page linked to above for details
