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 History

5 Guiding Principles Flexibility Performance Quality
The Guiding Principles of Everest: Documentation – A developer MUST be able to understand what each component of the framework does and it’s purpose Standards Compliance – The framework MUST generate, to the best of its ability, standards compliant messages Intuitiveness – The framework MUST behave as an extension of the developer’s environment. Performance – The framework MUST not introduce undue performance degradation to it’s container application Flexibility – The framework MUST allow developers to adapt to new HL7 standards with little changes to their application logic Standards Compliance Intuitiveness / Documentation

19 UV Support NE2008 (since GPMR 0.9.x) NE2009 / NE2010
*_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)

20 Patching NE2009/2010 Some MIFs duplicate the “true” option
<mif:class name="GuarantorChoice" isAbstract="true true"> Search / replace “true true” with “true” PORP_MT UV04 has invalid Type option <mif:type name=")"/> Replace name=“)” with name=“CS”

28 DT Enhancements

29 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..)

30 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);

31 Operator Example INT zero = 0; REAL pi = Math.PI; TS now = DateTime.Now; PQ day = new PQ(1, “d”); INT integerDiv = 3 / 2; REAL floatDiv = 3 / (REAL)2; TS yesterday = now – day; PQ negation = -day; REAL nullFlavored = pi / zero; NullFlavor nf = (pi / zero).NullFlavor; TS throwsAnException = now – new PQ(3, “ft”); Cast to/from native datatypes Natural operations on datatypes Null flavor rules still apply (nullFlavor = NI) Unit checking is performed

32 Implemented Operators
Comparison (<, >, <=, >=) Any PDV<T> where T is IComparable<T> Basic Arithmetic (+, -) TS, PQ, MO, INT, REAL Arithmetic (*, /) & Unary (-) PQ, MO, REAL, INT Integer Arithmetic (%, /) & Unary (--, ++) INT Logic (^, &, |, !) BL Casting (Implicit / Explicit) Many of the datatypes support this, many times when ToX or FromX is listed in the Data Types implementation guide.

33 Utility Functions To / from Interval: REAL pi = Math.PI;
pi.Precision = 2; IVL<REAL> piRange = pi.ToIVL(); TS ts2008 = new TS() { Value = “2008” }; IVL<TS> range2008 = ts2008.ToIVL(); Low = High = Low = High =

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

35 Set Utilities Periodic Interval:
IVL<TS> nineToFive = new IVL<TS>( DateTime.Parse(" :00 AM"), DateTime.Parse(" :00 PM") ); PIVL<TS> repeated = new PIVL<TS>( nineToFive, new PQ(1, "wk") TS y2kLunch = DateTime.Parse(" :30 AM"); bool isIncluded = repeated.Contains(y2kLunch ); // Returns false

36 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?

37 Example II a = new II(“ ”, “123”) { Use = InstanceIdentifierUse.Business }, b = new II(“ ”, “123”) { Use = InstanceIdentifierUse.Version } bool reference = a == b; bool value = a.Equals(b); bool semantics = a.SemanticEquals(b); False – A is not B False – Use is not equal True – A is equal to B according to Data Type rules.
