  2. Agenda • Overview • Architecture • Using Everest • Universal Messaging • Data types Enhancements • Roadmap

  3. Overview • HL7v3 Messaging API • Object representation of structures within MIFs • Improved v3 Experience • Extensive documentation in developer’s IDE • Value sets represented as business names • Parameterized constructors, operators and helper functions • Flexible ITS and Transport Channel architecture

  4. Guiding Principles Flexibility Performance Quality Standards Compliance Intuitiveness / Documentation

  14. Universal Messaging & CDA

  15. UV Support • NE2008 (since GPMR 0.9.x) • *_HD*.*mif files should be removed • NE2009 / NE2010 • HTML renderer works on Patched MIF files in quirks mode • Missing Several CMET definitions in DEFN IFC file • Templating issue with several Interactions • CDAr2 (NE2010) (since GPMR 1.1.x)

  16. Patching NE2009/2010 • Some MIFs duplicate the “true” option • <mif:class name="GuarantorChoice" isAbstract="true true"> • Search / replace “true true” with “true” • PORP_MT0500032UV04 has invalid Type option • <mif:type name=")"/> • Replace name=“)” with name=“CS”

  17. CDA in Everest

  18. CDA Support in Everest • GPMR 1.1 supports processing of POCD_MTxxxxxx MIFs • Everest 1.0 Supports rendering of the ClinicalDocument RMIM structure

  19. DT Enhancements

  20. Operators • HL7v3 data types should behave like native primitives when not null-Flavored • INT should behave like int, long, uint • REAL should behave like float, double • BL should behave like bool • Operator overloading allows us to achieve this: • Casting to/from native types • Adding nullFlavors • Providing native operations (+, -, /, *, %, <=, >=, etc..)

  21. Behaving Like Native Types for (int i = 0; i < 10; i++) if ((i % 2).Equals(1)) Console.WriteLine("{0} odd", i); for (INT i = 0; i < 10; i++) if ((i % 2).Equals(1)) Console.WriteLine("{0} odd", i);

  22. Set Utilities • Interval IVL<PQ> ageRange = new IVL<PQ>( new PQ(1, “a”), new PQ(3, “a”) ); ageRange.Contains(new PQ(24, ”mo”));

  23. Set Utilities • Periodic Interval: IVL<TS> nineToFive = new IVL<TS>( DateTime.Parse("2011-09-02 09:00 AM"), DateTime.Parse("2011-09-02 05:00 PM") ); PIVL<TS> repeated = new PIVL<TS>( nineToFive, new PQ(1, "wk") ); TS y2kLunch = DateTime.Parse("2000-01-01 11:30 AM"); boolisIncluded = repeated.Contains(y2kLunch ); // Returns false

  24. Three levels of Equality • Reference Equals (default == operation) • Do the two objects represent the same reference in memory • Value Equality (via .Equals()) • Do all of the properties in A have the same content as all the properties in B? • Semantically Equal (via .SemanticEquals()) • Are the two objects equal according to data types guide?
