17. NL 2002 NICTIZ & Stichting HL7 Nederland Conclusions The good news: the HL7 RIM seems fully sufficient to create the D-MIM for perinatology (classes and attributes). The bad news: Vocabulary domains are sometimes very hard to apply in practice.

18. NL 2002 NICTIZ & Stichting HL7 Nederland HL7 Netherlands is extending the current V3 products to a set of interactions and messages for a specific healthcare domain: –This process is therefore ahead of the current content of V3 itself. –Is this potentially conflicting with the main standardization process? –How are results from such a project fed back into the main standard? This week presentation to the Patient Care WG Feed back from HL7 org
