Summary
The HL7 SOA-Aware Enterprise Architecture provides HL7 with an Enterprise Architecture Framework, i.e. a set of constructs, Best Practices, processes, etc. that enable HL7 specifications to achieve cross-specification consistency and coherancy irrespective of the chosen interoperability paradigm (messages, documents, or services). SAEAF consists of four core "frameworks": Information (including RIM, data types, vocabulary bindings, etc.), Behavior (subsuming the existing Dynamic Model), Enterprise Conformance and Compliance (including HL7's existing Implementation and Conformance standards), and Governance. The SAEAF provides a framework for specification of standardized services that can be used by the HL7 community. It identifies artifacts and a constraint pattern that provides traceability from requirements. These specifications align with different levels of conformance that aid HL7 consumers in adopting standards in different contexts, and supports specific integration patterns between collaborators as they seek to achieve computable semantic interoperability.
Description
See the SAEAF Overview Snapshot presentation from September 2009 here.
Business Case (Intended Use, Customers)
- Enterprise interoperability projects including those building large-scale integrated health IT infrastructures at the national level
Benefits
- The main benefits that will be derived from developing specifications using the SAEAF including: consistency of specifications, enhanced ability to manage loosely-coupled complex interactions between multiple trading parters, increased cross-organization reuse of architecture primitives (realizing the value proposition of CMETs and extending that proposition to include behavioral as well as static semantic constructs).
