9、l Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activi
10、ty. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non- governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint technical commit
11、tee, ISO/IEC JTC 1. IEEE Standards documents are developed within the IEEE Societies and the Standards Coordinating Committees of the IEEE Standards Association (IEEE-SA) Standards Board. The IEEE develops its standards through a consensus development process, approved by the American National Stand
12、ards Institute, which brings together volunteers representing varied viewpoints and interests to achieve the final product. Volunteers are not necessarily members of the Institute and serve without compensation. While the IEEE administers the process and establishes rules to promote fairness in the
13、consensus development process, the IEEE does not independently evaluate, test, or verify the accuracy of any of the information contained in its standards. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of ISO/IEC JTC 1 is to p
14、repare International Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote. Attention is called to the possibili
15、ty that implementation of this standard may require the use of subject matter covered by patent rights. By publication of this standard, no position is taken with respect to the existence or validity of any patent rights in connection therewith. ISO/IEEE is not responsible for identifying essential
16、patents or patent claims for which a license may be required, for conducting inquiries into the legal validity or scope of patents or patent claims or determining whether any licensing terms or conditions provided in connection with submission of a Letter of Assurance or a Patent Statement and Licen
17、sing Declaration Form, if any, or in any licensing agreements are reasonable or non-discriminatory. Users of this standard are expressly advised that determination of the validity of any patent rights, and the risk of infringement of such rights, is entirely their own responsibility. Further informa
18、tion may be obtained from ISO or the IEEE Standards Association. ISO/IEC/IEEE 42010 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 7, Software and systems engineering, in cooperation with the Software and Systems Engineering Standards Committee of th
19、e Computer Society of the IEEE, under the Partner Standards Development Organization cooperation agreement between ISO and IEEE. This first edition of ISO/IEC/IEEE 42010 cancels and replaces ISO/IEC 42010:2007, which has been technically revised. ISO/IEC/IEEE 42010:2011(E) ISO/IEC 2011 All rights re
20、served IEEE 2011 All rights reserved vIntroduction The complexity of man-made systems has grown to an unprecedented level. This has led to new opportunities, but also to increased challenges for the organizations that create and utilize systems. Concepts, principles and procedures of architecting ar
21、e increasingly applied to help manage the complexity faced by stakeholders of systems. Conceptualization of a systems architecture, as expressed in an architecture description, assists the understanding of the systems essence and key properties pertaining to its behaviour, composition and evolution,
22、 which in turn affect concerns such as the feasibility, utility and maintainability of the system. Architecture descriptions are used by the parties that create, utilize and manage modern systems to improve communication and co-operation, enabling them to work in an integrated, coherent fashion. Arc
23、hitecture frameworks and architecture description languages are being created as assets that codify the conventions and common practices of architecting and the description of architectures within different communities and domains of application. This International Standard addresses the creation, a
24、nalysis and sustainment of architectures of systems through the use of architecture descriptions. This International Standard provides a core ontology for the description of architectures. The provisions of this International Standard serve to enforce desired properties of architecture descriptions.
25、 This International Standard also specifies provisions that enforce desired properties of architecture frameworks and architecture description languages (ADLs), in order to usefully support the development and use of architecture descriptions. This International Standard provides a basis on which to
26、 compare and integrate architecture frameworks and ADLs by providing a common ontology for specifying their contents. This International Standard can be used to establish a coherent practice for developing architecture descriptions, architecture frameworks and architecture description languages with
27、in the context of a life cycle and its processes (not defined by this International Standard). This International Standard can further be used to assess conformance of an architecture description, of an architecture framework, of an architecture description language, or of an architecture viewpoint
28、to its provisions. Users of this International Standard are advised to consult Clause 4 to gain appreciation of the provided ontology, its concepts and principles.

29、ngineering Architecture description 1 Scope This International Standard specifies the manner in which architecture descriptions of systems are organized and expressed. This International Standard specifies architecture viewpoints, architecture frameworks and architecture description languages for us
30、e in architecture descriptions. This International Standard also provides motivations for terms and concepts used; presents guidance on specifying architecture viewpoints; and demonstrates the use of this International Standard with other standards. 2 Conformance The requirements in this Internation
31、al Standard are contained in Clauses 5, 6 and 7. There are four situations in which claims of conformance with the provisions of this International Standard can be made. When conformance is claimed for an architecture description, the claim shall demonstrate that the architecture description meets t
32、he requirements listed in Clause 5. When conformance is claimed for an architecture viewpoint, the claim shall demonstrate that the architecture viewpoint meets the requirements listed in Clause 7. When conformance is claimed for an architecture framework, the claim shall demonstrate that the archit
33、ecture framework meets the requirements listed in 6.1. When conformance is claimed for an architecture description language, the claim shall demonstrate that the architecture description language meets the requirements listed in 6.3. Requirements of this International Standard are marked by the use
34、of the verb “shall”. Recommendations are marked by the use of the verb “should”. Permissions are marked by the use of the verb “may”. In the event of a conflict between normative figures and text, the text takes precedence. Please report any apparent conflicts. NOTE This International Standard is de
35、signed such that “tailoring” is neither required nor permitted for its use when claims of conformance are made. 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 architecting process of conceiving, defining, expressing, documenting, communicati
