Tuesday Q6 (19:00-21:00)

• Focus: this quarter focuses on SOA v3 implementation experiences
• Implementing hData (Gerald Beuchelt, Mitre)
  • Presentation on the topic of "mapping hData to in-memory RIM-based object structures" (the CS-CO or CS-RO cell transition in the technology matrix). The presentation will focus on the implementation of hData - and not on an explanation of hData itself.
  • hData is (using HL7 speak) a new XML ITS. See HData for an introduction, and www.projecthdata.org/ for detailed specifications, schema and FAQ.
  • How does this ITS compare to other ITSs when it comes to issues like code generation, code re-use and content validation?
• Query-By-Example (Jean-Henri Duteau, GP Informatics)
  • During the August 2010 harmonization meeting a new 'isCriterionInd' attribute was introduced in all Acts (it replaces all existing CRT moods). See [1] for details of the proposal.
  • The new attribute can be used to construct Query-By-Example (QBE) queries.
  • Jean will inform us about a) this new mechanism, and b) implementation experiences working with these queries in an SOA v3 [RIMBAA] environment.

Friday Q1 (09:00-10:30)

• Wrap-up, methodology issues surfaced by RIMBAA implementations
