CodeSystemVersion is a collection of assertions about one or more entities. If the state of a CodeSystemVersion is Final, the set of assertions made the resource is fixed, meaning that if one knows the documentURI assigned to the version and the specific sourceAndNotation from which the version instance was derived, the set of assertions is known as well.

If the state of a CodeSystemVersion is Final, the set of assertions made the resource is fixed, meaning that if one knows the documentURI assigned to the version and the specific sourceAndNotation from which the version instance was derived, the set of assertions is known as well. The name, URI and, if supported by the service, link to the code system that this version represents. A reference to a code system version whose assertions are included as part this code system version. the default spoken or written language used in this version A directory that, if resolved, will result in the complete list of all entities and their descriptions asserted by this code system version. This attribute will only be present if and only if the service implementation supports the EntityQuery service profile. A DirectoryURI that, when resolved by an instance of an AssociationQueryService will return a list of all associations asserted by this particular code system version A DirectoryURI that represents the set of EntityDescriptions that are of type owl:Class within this code system. Will only be present in code systems that represent ontologies. A DirectoryURI that represents the set of EntityDescriptions that are of type owl:ObjectProperty or owl:DataProperty within this code system. Will only be present in code systems that represent ontologies. A DirectoryURI that represents the set of EntityDescriptions that are of type owl:Individual within this code system. Will only be present in code systems that represent ontologies. An identifier that uniquely names this particular code system version within the context of the CTS₂ service instance. A CodeSystemVersionCatalogEntry read from a service instance. PSM A directory of CodeSystemVersion resources that meet a specified criteria. A synopsis of a CodeSystemVersion along with information about how to access the complete resource. The name, URI and, if supported by the service, link to the code system that this version represents. The tag(s) that assigned to this version by the service provider. codeSystemVersionTag identifies any roles that this version plays within the workflow of the current provider. As an example, a provider might assign the tags of "production" and "current" to a given code system version. With the exception of CURRENT the semantics of VersionTag are determined by the service provider. An identifier that uniquely names this particular code system version within the context of the CTS₂ service instance. A collection of complete CodeSystemVersion resources that meet a specified criteria. An instance of CodeSystemVersion that meets a specified filter criteria.
