28、tional Electrotechnical 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 fiel

29、ds of technical activity. 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 j

30、oint technical committee, ISO/IEC JTC 1. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of the joint technical committee is to prepare International Standards. Draft International Standards adopted by the joint technical commit

31、tee 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 drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO and IEC shall

32、 not be held responsible for identifying any or all such patent rights. ISO/IEC 19503 was prepared by the Object Mangement Group (OMG) and was adopted, under the PAS procedure, by Joint Technical Committee ISO/IEC JTC 1, Information technology, in parallel with its approval by national bodies of ISO

33、 and IEC. ISO/IEC 19503 is related to ISO/IEC 19501, Information technology Open Distributed Processing Unified Modeling Language (UML) Version 1.4.2 ISO/IEC 19502, Information technology Meta Object Facility (MOF) ITIC 2009 All rights reservedINCITS/ISO/IEC 19503:20052009ixIntroductionThe main purp

34、ose of this International Standard (XML) is to enable easy interchange of metadata between applicationdevelopment lifecycle tools (such as modeling tools based on the Unified Modeling Language (UML), ISO/IEC 19501, and metadata repositories/frameworks based on the Meta Object Facility (MOF), ISO/IEC

35、 19502) in distributed heterogeneous environments. This International Standard integrates three key industry standards: XML - eXtensible Markup Language, a W3C standard. UML - Unified Modeling Language, an OMG modeling specification, which is now ISO/IEC 19501. MOF - Meta Object Facility (ISO/IEC 19

36、502).The OMG adopted the XMI (version 1.0) in February 1999. It was developed as a response to a request for proposal, issued by the OMG Analysis and Design Task Force, for a model and metadata interchange facility. The purpose of the facility was to support the interchange of metadata (such as ODP

37、UML models). The most recent revision of XMI, 2.0, was submitted by the XMI Revision Task Force in October, 2002, and includes corrections and clarifications to the original specification, and changes to accommodate revisions to the 1.4 version of MOF.The rapid growth of distributed processing has l

38、ed to a need for a coordinating framework for this standardization and ITU-T Recommendations X.901-904 | ISO/IEC 10746, Open Distributed Processing Reference Model (RM-ODP) provides such a framework. It defines an architecture in which support of distribution, interoperability, and portability can b

39、e integrated. RM-ODP Part 2 (ISO/IEC 10746-2) defines the foundational concepts and modeling framework for describing distributed systems. RM-ODP Part 3 (ISO/IEC 10746-3) specifies a generic architecture of open distributed systems, expressed using the foundational concepts and framework defined in

40、Part 2. While not limited to this context, this International Standard is relevant to work on the standardization of OpenDistributed Processing (ODP).

While this International Standard addresses stream based metadata interoperability in the object analysis and design domain, XMI (in part because it is

47、MOF based) is equally applicable to metadata in many other domains.

48、005200934 XMI Schema Design Principles4.1 PurposeThis Clause contains a description of the XML Schemas that may be used with the XMI specification to allow some metamodel information to be verified through XML validation. The use of schemas in XMI is described first, followed by a brief description

49、of some basic principles, which includes a short description of each XML attribute and XML element defined by XMI. Those descriptions are followed by more complete descriptions that provide examples illustrating the motivation for the XMI schema design in the areas of metamodel class specification, transmitting incomplete metadata, linking, tailoring schema production, transmitting metadata differences, and exchanging d
