Health Level Seven, abbreviated to HL7, is a range of global standards for the transfer of clinical and administrative health data between applications with the aim to improve patient outcomes and health system performance. The HL7 standards focus on the application layer, which is "layer 7" in the Open Systems Interconnection model.
HL7 was founded in 1987 to produce a standard for the exchange of data with hospital information systems.Donald W. Simborg, the CEO of Simborg Systems took the initiative to create the HL7 organization with the aim to allow for wider use of its own exchange protocol (known as the StatLAN protocol, originally defined at the University of California, San Francisco in the late 1970s).
FHIR builds on previous data format standards from HL7, like HL7 version 2.x and HL7 version 3.x. But it is easier to implement because it uses a modern web-based suite of API technology, including a HTTP -based RESTful protocol, and a choice of JSON , XML or RDF for data representation. [ 1 ]
The HL7 Clinical Document Architecture (CDA) is an XML-based markup standard intended to specify the encoding, structure and semantics of clinical documents for exchange. In November 2000, HL7 published Release 1.0. The organization published Release 2.0 with its "2005 Normative Edition". [1]
The HL7 Services-Aware Interoperability Framework Canonical Definition (SAIF-CD) [3] provides consistency between all artifacts, and enables a standardized approach to enterprise architecture (EA) development and implementation, and a way to measure the consistency.

Like other HL7 formats, it is XML based. The HL7 aECG standard was created in response to the Food and Drug Administration’s digital electrocardiogram initiative which was introduced November, 2001.
