The Health Level Seven International Standards Development Organization (HL7) is an international community, working together towards a common goal of improving patient care through technology. HL7 interoperability protocols include messaging standards, decision support standards, clinical document standards, Electronic Health Record (EHR) functional requirements, drug product labeling standards, and more. Many of these protocols are specifically called out in the meaningful use final rules for the HITECH Act.

In addition, HL7 defines Electronic Health Record (EHR) and Personal Health Record (PHR) functional requirements, which provide a reference list of functions that may be present in an EHR. The function list is described from a user perspective with the intent to enable consistent expression of system functionality. In 2009, the HL7 EHR-System Functional Model became an internationally recognized ISO standard (PDF on the HL7 site), setting the stage to achieve common functionality of EHRs globally.

SAIF should be regarded as an adjunct to any EAF (Enterprise Architecture Framework) which focuses on Working Interoperability (WI). It is a framework which brings from service-oriented architecture (SOA) practice, two critical constructs which significantly enhance the path to WI, that is:

1. Separation of concerns (static versus behavioral semantics)
2. Formal notion of contracts

SAIF is interoperability paradigm neutral (documents, messages, open enough to be implemented for all or one or a few types of interoperability paradigms (messages, documents, or services).

Intended usea of SAIF include enterprise interoperability projects including those building large-scale integrated health IT infrastructures at the national level.
