Archetype +An archetype is a re-usable, formal model 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. scharge referral, prescription, diagnosis., An Archetype is the formal definition of p 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. ta values may take, and other constraints., 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
Archetype Definition Language +ADL is a formal language for expressing ar ADL is a formal language for expressing archetypes. It provides a formal, textual syntax for describing constraints on any domain entity whose data is described by an information model (also known as the 'underlying reference model'). The ADL syntax is semantically equivalent to the AOM, and represents one possible serialisation of the AOM. The current version of ADL is known as 'ADL 1.5'. rent version of ADL is known as 'ADL 1.5'., Archetype Definition Language (ADL) is a formal language for expressing archetypes.
Archetype Instance +Individual 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
Archetype Object Model +The AOM is the definitive expression of ar The AOM is the definitive expression of archetype semantics, and is independent of any particular syntax. The AOM is defined as an object model, using a UML class diagram. It is a generic model, meaning that it can be used to express archetypes for any reference model in a standard way. Version 1.4 of the AOM was standardised in ISO-13606:2. The current version is known as 'AOM 1.5'. The current version is known as 'AOM 1.5'.
Archetype Query Language +Archetype Query Language (AQL) is a declar Archetype Query Language (AQL) is a declarative query language developed specifically for expressing queries used for searching and retrieving the clinical data found in archetype-based EHRs. AQL expresses the queries at the archetype level, i.e. semantic level, other than at the data instance level. This is the key in achieving sharing queries across system boundaries or enterprise boundaries. ystem boundaries or enterprise boundaries.

Code System +A Code System is a managed collection of C A Code System is a managed collection of Concept Representations, including codes, but sometimes more complex sets of rules and references, optionally including additional Concept Representations playing various roles including identifiers of the concepts, designations, etc. ifiers of the concepts, designations, etc., An organized collection of terms established by an authoritative source such as a Standards Development Organization (SDO). Examples of Code Systems are SNOMED-CT®, ICD-9-CM, and LOINC®., system of codes, descriptions, designations, properties and relationships also sometimes known as "vocabulary", "terminology", "coding scheme", "classification scheme" and "ontology"
Common Terminology Services 2.0 +CTS2 is a specification that provides a st CTS2 is a specification that provides a standard interface to disparate terminology sources. The Information Model specifies the structural definition, attributes and associations of Resources common to structured terminologies such as Code Systems, Binding Domains and Value Sets. The Computational Model specifies the service descriptions and interfaces needed to access and maintain structured terminologies. ess and maintain structured terminologies.
Concept +A Concept is an abstract thought about a t A Concept is an abstract thought about a thing, orÊthings, in the world. It the basic unit of communication and each concept represents an atomic unit of thought that references a concrete or abstract thing. A single concept may be represented using either a single code, a defining expression or a structure of other concepts from which this concept is defined. ncepts from which this concept is defined., A Concept is a unitary mental representati A Concept is a unitary mental representation of a real or abstract thing – an atomic unit of thought. It should be unique in a given Code System. A concept may have synonyms in terms of representation and it may be a singleton, or may be constructed of other concepts (i.e. post-coordinated concepts). concepts (i.e. post-coordinated concepts)., In SNOMED CT, each concept is uniquely identified by a concept ID, and a Fully Specified Name (FSN). SNOMED CT concepts may be formally defined in terms of their relationships with other concepts.,
Conceptual Information Model +An abstract model focusing on the 'concept An abstract model focusing on the 'conceptual perspective'. CIMs may not define attributes and when they do, they do not define specific codes or code systems from which semantic types might originate. CIMs maintain maximal reuse capability. They allow a domain expert to provide requirements in their language and allow a terminologist, downstream in the development process, to assign appropriate value sets or code-system content to each abstract semantic type. em content to each abstract semantic type., A CIM is also often referred to as a busin A CIM is also often referred to as a business or domain model because it uses a vocabulary that is familiar to the subject matter experts (SMEs). It presents exactly what the system is expected to do, but hides all information technology related specifications to remain independent of how that system will be (or currently is) implemented. tem will be (or currently is) implemented.

DL-Based Reference Terminology +A high quality controlled terminology, whe A high quality controlled terminology, where each concept has a formal, logical definition, usually provided by an ontology, which is consistent between and within systems, has consistent meaning over time, and has deterministic (computable) meaning. The objective of a DL-based Reference Terminology is to be widely used, where the meaning is useful, able to be communicated-to and understood-by many average health care providers without reference to inaccessible, hidden or private meanings.
