This International Standard specifies the shared semantics for a collection of healthcare related datatypes used in a number of health related information standards. This standard declares these datatypes using the terminology, notations and datatypes defined in 11404 rev 2003. In addition to defining the datatypes in these terms, this standard also provides UML definitions of the same datatypes using the terminology, notation and types defined in UML 2.0.
These datatypes provide an agreed common semantic basis for exchanging basic concepts that are commonly encountered in healthcare environments. This standard is based on considerable input from HL7, CEN, and past ISO work on healthcare datatypes.
There is no clear definition of exactly what is a datatype and where a more complex structure would be appropriate (This is discussed in depth in section X). Healthcare specifications are invited to use these datatypes as the basis for further development of complex healthcare information standards and specifications but these specifications may choose not to use all the types defined in this specification. In this case, it would appropriate for a specification to provide an implementation guide describing how the basic semantic concepts described in this standard are implemented in the specification.
