Definition: A re-usable, formal model of a concept expressed as a computable set of constraint statements, on an underlying reference model (URM).
Reference Definition: An archetype is a re-usable, formal model of a domain concept. An archetype is expressed as a computable set of constraint statements, on an underlying reference model (URM). Concepts that can be modelled using archetypes include weight measurement, blood pressure, microbiology results, discharge referral, prescription, diagnosis. (openEHR Foundation website)
Reference Definition: An Archetype is the formal definition of prescribed combinations of the building-block classes defined in the Reference Model for particular clinical domains or organizations. An archetype is a formal expression of a distinct, domain-level concept, expressed in the form of constraints on data whose instances conform to the reference model. For an EHR_Extract, as defined in this part of ISO 13606, an archetype instance specifies (and effectively constrains) a particular hierarchy of RECORD_COMPONENT sub-classes, defining or constraining their names and other relevant attribute values, optionality and multiplicity at any point in the hierarchy, the data types and value ranges that ELEMENT data values may take, and other constraints. (ISO 13606)
Reference Definition: metadata class instance of an archetype model, specifying the clinical concept and the value constraints that apply to one class of record component instances in an electronic health record extract (CEN/ISO 13606)
Usage Note: Concepts that can be modelled using archetypes include weight measurement, blood pressure, microbiology results, discharge referral, prescription, diagnosis. CIMI archetypes will be represented as an instance of the ‘Archetype Object Model’.
