The work of preparing International Standards is normally carrie
24、d out through ISO technical committees. Each member body interested 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. IS
25、O collaborates closely with the International Electrotechnical 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 Internatio
26、nal Standards. Draft International Standards adopted by the 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 ele
27、ments of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 12967-2 was prepared by Technical Committee ISO/TC 215, Health informatics, based on the European Standard EN 12967-2:2007 with minor editorial amendments.
28、 ISO 12967 consists of the following parts, under the general title Health informatics Service architecture: Part 1: Enterprise viewpoint Part 2: Information viewpoint Part 3: Computational viewpoint BS EN ISO 12967-2:2011ISO 12967-2:2009(E) vi ISO 2009 All rights reservedIntroduction This is the se
29、cond part of ISO 12967, a multi-part standard that provides guidance for the description, planning and development of new systems as well as for the integration of existing information systems, both within one enterprise and across different healthcare organizations through an architecture integrati
30、ng the common data and business logic into a specific architectural layer (i.e. the middleware), distinct from individual applications and accessible throughout the whole information system through services, as shown in Figure 1. Middleware of objectsintegrating common data and common business logic
31、ApplicationsScope of the standardFigure 1 Scope The overall architecture is formalized according to ISO/IEC 10746 (all parts) and is therefore structured through the following three viewpoints. a) Enterprise viewpoint: specifies a set of fundamental common requirements at enterprise level with respe
32、ct to the organizational purposes, scopes and policies that must be supported by the information and functionality of the middleware. It also provides guidance on how one individual enterprise (e.g. a regional healthcare authority, a large hospital or any other organization where this model is appli
33、cable) can specify and document additional specific business requirements, with a view to achieving a complete specification, adequate for the characteristics of that enterprise. Enterprise viewpoint is specified in ISO 12967-1. b) Information viewpoint: specifies the fundamental semantics of the in
34、formation model to be implemented by the middleware to integrate the common enterprise data and to support the enterprise requirements formalized in ISO 12967-1. It also provides guidance on how one individual enterprise can extend the standard model with additional concepts needed to support local
35、requirements in terms of information to be put in common. Information viewpoint is specified in this part of ISO 12967. c) Computational viewpoint: specifies the scope and characteristics of the services that must be provided by the middleware for allowing access to the common data as well as the ex
36、ecution of the business logic supporting the enterprise processes identified in the information viewpoint and in ISO 12967-1. It also provides guidance on how one individual enterprise can specify additional services needed to support local specific requirements in terms of common business logic to
37、be implemented. Computational viewpoint is specified in ISO 12967-3. BS EN ISO 12967-2:2011INTERNATIONAL STANDARD ISO 12967-2:2009(E) ISO 2009 All rights reserved 1Health informatics Service architecture Part 2: Information viewpoint 1 Scope This part of ISO 12967 specifies the fundamental character
38、istics of the information model to be implemented by a specific architectural layer (i.e. the middleware) of the information system to provide a comprehensive and integrated storage of the common enterprise data and to support the fundamental business processes of the healthcare organization, as def
39、ined in ISO 12967-1. The information model is specified without any explicit or implicit assumption on the physical technologies, tools or solutions to be adopted for its physical implementation in the various target scenarios. The specification is nevertheless formal, complete and non-ambiguous eno
40、ugh to allow implementers to derive an efficient design of the system in the specific technological environment that will be selected for the physical implementation. This specification does not aim at representing a fixed, complete, specification of all possible data that can be necessary for any r
41、equirement of any healthcare enterprise. It specifies only a set of characteristics, in terms of overall organization and individual information objects, identified as fundamental and common to all healthcare organizations, and that is satisfied by the information model implemented by the middleware
42、. Preserving consistency with the provisions of this part of ISO 12967, physical implementations allow extensions to the standard information model in order to support additional and local requirements. Extensions include both the definition of additional attributes in the objects of the standard mo
43、del, and the implementation of entirely new objects. Also this standard specification is extensible over time according to the evolution of the applicable standardization initiatives. The specification of extensions is carried out according to the methodology defined in ISO 12967-1:2009, Clause 7, “
44、Methodology for extensions”. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.

It consists of a formal information model detailing the semantic and syntactic aspects of all data to be managed.
