19、(E) iv ISO 2011 All rights reservedForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body in
20、terested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechni
21、cal Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the
22、 technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.
23、 ISO shall not be held responsible for identifying any or all such patent rights. ISO 21090 was prepared by Technical Committee ISO/TC 215, Health informatics.

24、in HL7 and the support of Connecting for Health have been instrumental in the preparation of this International Standard, which is a shared document between Health Level Seven (HL7) and ISO, and has been produced according the terms of the agreement between HL7, CEN and ISO (JIC, see http:/www.globa
25、l-e-health-standards.org/), which ensures that the content is fully available through ISO, CEN and HL7 publication channels.

26、ange 1 Scope This International Standard provides a set of datatype definitions for representing and exchanging basic concepts that are commonly encountered in healthcare environments in support of information exchange in the healthcare environment; specifies a collection of healthcare-related datat
27、ypes suitable for use in a number of health-related information environments; declares the semantics of these datatypes using the terminology, notations and datatypes defined in ISO/IEC 11404, thus extending the set of datatypes defined in that standard; provides UML definitions of the same datatype
28、s using the terminology, notation and types defined in Unified Modelling Language (UML) version 2.0; specifies an XML (Extensible Mark-up Language) based representation of the datatypes. The requirements which underpin the scope reflect a mix of requirements gathered primarily from HL7 Version 3 and
29、 ISO/IEC 11404, and also from CEN/TS 14796, ISO 13606 (all parts) and past ISO work on healthcare datatypes. This International Standard can offer a practical and useful contribution to the internal design of health information systems, but is primarily intended to be used when defining external int
30、erfaces or messages to support communication between them. 2 Normative references The following referenced documents are indispensable for the application of this document.
