Support Package

The Support Reference Model comprises types used throughout the openEHR models, including assumed primitive types defined outside of openEHR. The package structure is illustrated below. The assumed_types 'pseudo-package' stands for types assumed by the openEHR specifcations to exist in an implementation technology, such as a programming language, schema language or database environment. The four Support packages define the semantics respectively for constants, terminology access, access to externally defined scientific units and conversion information. The class EXTERNAL_ENVIRONMENT_ACCESS is a mixin class providing access to the service interface classes.
