HL7-HSRA

Return to Service Oriented Architecture WG

---

Project Information

The objective of the HL7 Health Service Reference Architecture (HL7-HSRA) is to support the design of medium/large scale eHealth architectures based on HL7 services and standards.

Building Enterprise Service architectures requires an understanding of composite solutions that include different services organized in choreographies and/or orchestrations which cover many areas within medium to large-scale organizations. The intent of the HL7-HSRA is to support the process of architectural design with a map of building blocks and solution patterns based on existing HL7 Standards.

This project organizes HL7 completed Service Functional Models, Functional Profiles and Domain Models into:
- a formalized Enterprise Service Inventory
- an Architectural Patterns Catalog
- associated methods for enterprise Service discovery and orchestration

The role of specific technology/standard service implementations (FHIR, OMG/HL7 Soap services, IHE XD* family) will be discussed.

The audience of the HL7-HSRA will be principally focused on architects and CIOs that need to design, plan and evaluate enterprise wide solutions for complex organizations.

However, the project is relevant also for the internal HL7 audience. The HSRA outcome verify the consistency of HL7 standard and potential area not fully covered or with relevant overlapping. The Pattern Catalog can also support the mapping between different HL7 standard for the behavioural aspects (e.g. V2-V3-FHIR)

In addition to HL7 Standards, existing standards for Service representation and modelling will be considered including OpenGroup Archimate, OMG SOAml, OMG BPMN, OMG Structured Patterns Metamodel(SPMS), OMG Unified Architecture Framework (UAF), OpenGroup Togaf and the OASIS SOA Repository Artifact Model and Protocol (S-RAMP).
