HL7 Services-Aware Enterprise Architecture Specification (SAEAF)


Standard Category

Modeling Standards

Integration Paradigm

Documents, Messages, Services




SAEAF (The HL7 SOA-Aware Enterprise Architecture Framework) 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":
(1) Information (including RIM, data types, vocabulary bindings, etc.),
(2) Behavior (subsuming the existing Dynamic Model),
(3) Enterprise Conformance and Compliance (including HL7's existing Implementation and Conformance standards), and
(4) Governance.


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


The main benefits that will be derived from developing specifications using the SAEAF include: consistency of specifications, enhanced ability to manage loosely-coupled complex interactions between multiple trading partners, 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)
