HL7 Version 3 Methodology: Service Oriented Architecture; Service Definition, Release 1
This document describes a methodology for defining services within the healthcare domain, in particular, for areas covered by Health Level Seven (HL7) domain content; an effort known as Service Oriented Architecture for Health Level Seven (SOA4HL7). It is accompanied by a set of deliverables relating to infrastructure and architecture that collectively form the overall approach. This methodology is aimed at providing guidance that will help identify and enumerate services based on existing HL7 messaging artifacts. It also provides a practical approach to HL7 work groups interested in SOA. By following this methodology, the user should be able to produce appropriate (from a SOA perspective) service definitions, which may then be proposed as standards that could be balloted through the main Healthcare Services Specification Project (HSSP) process.
- HL7 work groups that need to define services
- Standards development organizations (SDOs), software vendors, healthcare payers or providers, etc. wanting to define automated services
- One of the main benefits of SOA is to enable loose coupling which frees the service consumer from the details of the implementation of the service itself.
- US Food and Drug Association (FDA) approved package insert labels (HL7 Structured Product Labeling)
A number of years ago, Object Management Group (OMG) approached HL7 about how we might jointly develop a capacity for implementing HL7 in a services oriented architecture. Working together, HL7 and OMG developed this methodology. This is intended to complement the Service Specification Framework (SSF) defined within the HSSP, but also provide an interim method of defining and implementing web services based on HL7 Version 3 artifacts.
The standard is not published separately, but is available as part of the Health Level Seven Version 3 (V3) Normative Edition. See the HL7 Version 3 Product Suite for downloads.
