It supersedes BS ISO/IEC TR10000-2:1994 which i
3、s withdrawn. The UK participation in its preparation was entrusted to Technical Committee IST/-/10, Technical coordination panel for IST/-, which has the responsibility to: aid enquirers to understand the text; present to the responsible international/European committee any enquiries on the interpre
4、tation, or proposals for change, and keep the UK interests informed; monitor related international and European developments and promulgate them in the UK. A list of organizations represented on this committee can be obtained on request to its secretary. From1 January1997, all IEC publications have
5、the number60000 added to the old number. For instance, IEC27-1 has been renumbered as IEC60027-1. For a period of time during the change over from one numbering system to the other, publications may contain identifiers from both systems.

National bodies that are members of ISO or I
23、EC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, gov
24、ernmental 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 committee, ISO/IEC JTC1. The main task of technical committees is to prepare International Standards. In exceptional circums
25、tances a technical committee may propose the publication of a Technical Report of one of the following types: type1, when the required support cannot be obtained for the publication of an International Standard, despite repeated efforts; type2, when the subject is still under technical development o
26、r where for any other reason there is the future but not immediate possibility of an agreement on an International Standard; type3, when a technical committee has collected data of a different kind from that which is normally published as an International Standard (“state of the art”, for example).
27、Technical reports of types1 and2 are subject to review within three years of publication, to decide whether they can be transformed into International Standards. Technical Reports of type3 do not necessarily have to be reviewed until the data they provide are considered to be no longer valid or usef
28、ul. ISO/IEC TR10000-2, which is a Technical Report of type3, was prepared by Joint Technical Committee ISO/IEC JTC1, Information technology. This fourth edition cancels and replaces the third edition (ISO/IEC TR10000-2:1994), which has been technically revised. ISO/IEC TR10000 consists of the follow
29、ing parts, under the general title Information technology Framework and taxonomy of International Standardized Profiles: Part1: General principles and documentation framework; Part2: Principles and Taxonomy for OSI profiles; Part3: Principles and Taxonomy for Open System Environment profiles.ISO/IEC
30、TR10000-2:1995 BSI 09-1999 1 Introduction The context of Functional Standardization is one part of the overall field of Information Technology standardization activities covering Base standards, which define fundamentals and generalized procedures. They provide an infrastructure that can be used by
31、a variety of applications, each of which can make its own selection from the options offered by them. Profiles, which define conforming subsets or combinations of base standards used to provide specific functions. Profiles identify the use of particular options available in the base standards, and p
32、rovide a basis for the development of uniform, internationally recognized, conformance tests. Registration mechanisms, which provide the means to specify detailed parameterization within the framework of the base standards or profiles. Within ISO/IEC JTC1, the process of Functional Standardization i
33、s concerned with the methodology of defining profiles, and their publication in documents called “International Standardized Profiles” (ISPs) in accordance with procedures contained in Directives of JTC1. The scope of Information Technology standardization to which this process is being applied is t
34、hat which corresponds to the generally understood, but loosely defined, concept of “Open Systems”. The objective is to facilitate the specification of IT systems characterized by a high degree of interoperability and portability of their components. In addition to ISO/IEC TR10000, the secretariat of
35、 the Special Group on Functional Standardization maintains a standing document (SD-4) entitled “Directory of ISPs and Profiles contained therein”. This is a factual record of which ISPs exist, or are in preparation, together with an executive summary of each profile. It is subject to regular updatin
36、g by the Secretariat of ISO/IEC JTC1/SGFS. 1 Scope The purpose of this part of ISO/IEC TR10000 is to provide principles and a classification scheme for OSI profiles which may be or have been submitted for ratification as International Standardized Profiles (ISPs). ISO/IEC TR10000-1 defines the conce
37、pt of profiles which are documented in ISPs. OSI profiles are a subset of OSE profiles. ISO/IEC TR10000-3 defines the concept of OSE profiles and, along with ISO/IEC TR10000-1, gives guidance to organizations making proposals for Draft ISPs, on the nature and content of the documents they are produc
38、ing. The existence of a profile classification in this part of ISO/IEC TR10000 does not reflect a judgment by ISO/IEC JTC1/SGFS that a profile is required for such capability. It merely provides a capability to identify uniquely such a function and to enable evaluation of PDISPs. Since profiles will
39、 be proposed according to needs identified to SGFS and according to the progress of international base standardization, the Taxonomy will be periodically updated or have new parts added in order to reflect the progress reached. It is also recognized that there will be proposals for the extension of
40、the Taxonomy to cover functions which were not identified during preparation of this edition of ISO/IEC TR10000. These extensions, may be identified by a variety of proposers and involve simple extensions to the existing Taxonomy or the addition of new functional areas not currently covered by ISO/I
41、EC TR10000. The inclusion of such extensions is administered following the procedures elaborated by SGFS. A distinction has been made between a profile and an ISP documenting one or more profiles. The Taxonomy is only concerned with profiles, but further information is given in the “Directory of ISP
42、s and Profiles contained therein” as to which ISP contains the documentation of a profile. This Directory is maintained as an SGFS standing document SD-4 (see Annex A). For each draft profile submitted to SGFS, it will also provide additional information, including the status of the identified profi
43、les. 2 References The following standards contain provisions which, through reference in this text, constitute provisions of this part of ISO/IEC TR10000.
