  1. MARC-HI Everest Framework HL7v3 API Architecture Overview February 2, 2010

  2. Agenda • Introduction • Overview • What is the Everest Framework? • Components • From HL7v3 MIF to XML Instance • Developer Experience

  3. What is the Everest Framework? • Everest is the foundation for an HL7v3 Messaging API • Class/Object representation of structures from pCS MIFs • Improved v3 experience • Extensive documentation in developer’s IDE • Parameterized constructors, operators, and helper functions • Flexible ITS and Transport layers • Current version .NET based

  4. Components • Data-Types • Hand written • Combination of R1 and R2 data type structures • Provide validation, operator overloading and other valuable functionality (compression, formatting data, etc..) • RMIM Classes • Automatically generated from MIF v2

  5. Components (Cont’d) • Formatters • (De)Serializes class structures a variety of formats (XML, Binary, etc...) • Can be combined • Provide validation support • Optimizes mass processing of HL7v3 structures • Connectors • Transports classes to/from remote endpoints using HL7v3

  8. From MIF to Instance Formatters Data Types XML ITS 1.x Generated DLL Data Type R1 RMIM Classes Application Code Vocabulary GPMR Create No ITS? Use Structures <PRPA_IN1012..<id root=“” MIF v2 XML ITS1.0 with DT R1

  9. Sending the Instance Connector WCF Formatter Remote System Application Code RMIM RMIM <PRPA_IN1012..<id root=“…<versionCod Send <PRPA_IN1012..<id root=“”
