MARC-HI Everest Framework
Enabling RMIM Based ApplicationsJustin Fyfe (Mohawk College)
Agenda
• Overview• Architecture• Using Everest• Universal Messaging• Data types Enhancements• Roadmap
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

UNIVERSAL MESSAGING & CDA
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)
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”
CDA IN EVEREST
CDA Support in Everest
• GPMR 1.1 supports processing of POCD_MTxxxxxx MIFs
• Everest 1.0 Supports rendering of the ClinicalDocument RMIM structure
DT ENHANCEMENTS
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..)
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);
Set Utilities
• IntervalIVL<PQ> ageRange = new IVL<PQ>(
new PQ(1, “a”),new PQ(3, “a”)
);ageRange.Contains(new PQ(24, ”mo”));
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"); bool isIncluded = repeated.Contains(y2kLunch ); // Returns false
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?
ROADMAP
Milestones• Q4 2011 – jEverest CTP (Community Tech. Preview)
– Formatters– RMIM Structures – GPMR Patches
• Q1 2012 – Release Candidate 3– Everest .NET:
• CDA Support• Datatypes R2 Support
– jEverest :• Connectors
• Q2 2012 – Release of Everest 1.0– jEverest + Everest + GPMR Bundles– Documentation for jEverest
