Mission
The Services Oriented Architecture SIG (SOA) supports the HL7 mission to promote and create standards by identifying common architectural "services" and their behaviors and establishing an industry position on the form these services take. The ServicesSIG will produce Service Functional Models (SFMs) which will be balloted HL7 standards declaring the functions and information appropriate to them. The SOA SIG will identify service candidates, prioritize and determine functional boundaries for those services, relating them to existing HL7 content and other relevant standards.
These services will promote the interoperability of healthcare systems, including but not limited to EHR systems for inter-product, intra-organization, inter-organization, regional, and national efforts.
Charter
Work Products and Contributions to HL7 Processes
- To establish a set of common architectural services (e.g., behavioral specifications) in the form of a Service Functional Model for each service determined to be of priority to the HL7 community.
- To establish a methodology for consistently specifying services within HL7 and work with the Modeling and Methodology Committee to harmonize this into the HL7 Development Framework
- To establish a common reusable infrastructure supportive of modeling and specifying services.
- To coordinate under the existing Memorandum of Understanding with the Object Management Group in the creation of technical specifications supportive of the HL7 standards.
- To identify existing HL7 content (information models, vocabularies/terminologies, messaging protocols, application roles, storyboards, and so on) relevant to services and to relate them in service specifications.
- To support other HL7 committees engaged in service specification work.
- To produce a "roadmap" document describing the services landscape, identifying the breadth of candidates and service interdependencies, and including a taxonomy of services.
Formal Relationships With Other HL7 Groups
This SIG will be sponsored by the EHR Technical Committee. Initial collaborations are expected with the Vocabulary TC, Clinical Decision Support TC, Patient Care TC, the Templates SIG, and the Modeling and Methodology Committee. SOA SIG will actively work with any committee demonstrating interest, working with that committee in whatever partnership arrangement they prefer.
Formal Relationship With Groups Outside of HL7
This SIG will include representation from the Object Management Group in accordance with the liaison agreement between HL7 and that organization. Currently joint activities are being explored with IHE, CEN and X.12 and would be subject to HL7 Policies and Procedures governing those relationships. The Eclipse Open Healthcare Framework (Eclipse OHF) group has established a public position supporting this work, and the SOA SIG will work with that organization as they implement services.
