MARC-HI Everest Framework HL 7 v 3 API Architecture Overview February 2, 2010
Agenda • Introduction • Overview – What is the Everest Framework? – Components – From HL 7 v 3 MIF to XML Instance • Developer Experience
What is the Everest Framework? • Everest is the foundation for an HL 7 v 3 Messaging API – Class/Object representation of structures from p. CS MIFs – Improved v 3 experience • Extensive documentation in developer’s IDE • Parameterized constructors, operators, and helper functions – Flexible ITS and Transport layers – Current version. NET based
Components • Data-Types – Hand written – Combination of R 1 and R 2 data type structures – Provide validation, operator overloading and other valuable functionality (compression, formatting data, etc. . ) • RMIM Classes – Automatically generated from MIF v 2
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 HL 7 v 3 structures • Connectors – Transports classes to/from remote endpoints using HL 7 v 3
