Archetype (information science)

In the field of informatics, an archetype is a formal re-usable model of a domain concept. Traditionally, the term archetype is used in psychology to mean an idealized model of a person, personality or behaviour (see Archetype). 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:

The modern Archetype formalism is specified and maintained by the openEHR Foundation, and although originally developed for the health IT domain, is completely domain-independent, and has been used in geospatial modelling, telecommunications, and defence.

The Archetype Formalism consists of a number of specifications including:

The Archetype Technology Overview provides a short technical overview of the archetype formalism useful for new users.

The ADL/AOM 1.4 specifications were provided to ISO TC 215 in 2008 and became the ISO 13606-2 standard, extant until 2017. ISO TC 215 has accepted the AOM 2 specification as the basis for a revision of this standard, to be issued in 2017.

In late 2015, the Object Management Group (OMG) accepted an RfP entitled 'Archetype Modeling Language (AML)' as a new candidate standard. This specification is a form of ADL re-engineered as a UML profile so as to enable archetype modelling to be supported within UML tools.

A number of tools area available for working with archetypes. Most are listed on the openEHR modelling tools page. They include:
