In the field of informatics, an archetype is a formal re-usable model of a domain concept.
The usage of the term in informatics is derived from this traditional meaning, but applied to domain modelling instead.
An archetype is defined by the OpenEHR Foundation (for health informatics) as follows:[1] The modern archetype formalism is specified and maintained by the openEHR Foundation,[oe 1] and although originally developed for the health IT domain, is completely domain-independent, and has been used in geospatial modelling, telecommunications, and defence.
ISO TC 215 accepted the AOM 2 specification[oe 6] as the basis for a revision of this standard, which was issued in 2019.
[3] In late 2015, the Object Management Group (OMG) accepted an RfP entitled 'Archetype Modeling Language (AML)' as a new candidate standard.
