The vocabulary domain consists of: Value Sets, Value Set Concepts, Code Systems, Code System Concepts, Views (Messaging Guides), and Groups.
HL7 Version 3 Core Principles Definition:
A Value Set represents a uniquely identifiable set of valid concept representations, where any concept representation can be tested to determine whether or not it is a member of the value set. It is also the default vocabulary object on the PHIN VADS Search page.
HL7 Version 3 Core Principles Definition:
A code system is a managed collection of concept identifiers, usually codes, but sometimes more complex sets of rules and references. They are often described as collections of uniquely identifiable concepts with associated representations, designations, associations, and meanings. Examples of code systems include ICD-9 CM, SNOMED CT, LOINC, and CPT. To meet the requirements of a code system as defined by HL7, a given concept representation must resolve to one and only one meaning within the code system. In the terminology model, a code system is represented by the Code System class. Code systems are often referred to as terminologies, vocabularies, or coding schemes.
HL7 Version 3 Core Principles Definition:
A concept defines 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 primitive or compositional term.
Examples:
(a) Tuberculosis Message Mapping Guide Vocabulary View
(b) Healthcare Associated Infection CDA Implementation Guide Vocabulary View.
Examples:
(a) The Demographics group will contain all of the value sets related to demographics such as Countries, Counties, Cities, Sex, etc.
(b) The Laboratory group will contain all of the value sets related to Lab tests and results such as specimen or sample type, Hepatitis Lab Tests, Microorganism, etc.
These PHIN Vocabulary Groups roughly follow the scope of the White House E-Gov Consolidation Health Informatics (CHI) domains.
