National bodies that are members of ISO or IEC participate

29、 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, governmental or n

30、on-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. In addition to developing International Standards, ISO/IEC JTC1 has created a Special Group on Functional Standard

31、ization for the elaboration of International Standardized Profiles. An International Standardized Profile is an Internationally agreed, harmonized document which identifies a standard or group of standards, together with options and parameters, necessary to accomplish a function or set of functions.

32、 Draft International Standardized Profiles are circulated to national bodies for voting. Publication as an International Standardized Profile requires approval by at least75% of the national bodies casting a vote. International Standardized Profile ISO/IECISP10607-5 was prepared with the collaborati

37、dized Profiles”. The context of Functional Standardization is one part of the overall field of Information Technology (IT) standardization activities, covering base standards, profiles, and registration mechanisms. A profile defines a combination of base standards that collectively perform a specifi

38、c well-defined IT function. Profiles standardize the use of options and other variations in the base standards, and provide a basis for the, development of uniform, internationally recognized system tests. One of the most important roles for an ISP is to serve as the basis for the development (by or

39、ganizations other than ISO and IEC) of internationally recognized tests and test centres. ISPs are produced not simply to legitimize a particular choice of base standards and options, but to promote real system interoperability. The development and widespread acceptance of tests based on this and ot

40、her ISPs is crucial to the successful realization of this goal. The text for this part of ISO/IEC ISP10607 was developed in close co-operation among the FTAM Expert Groups of the three International OSI/OSE Workshops: OSE Implementors Workshop (OIW), the European Workshop for Open Systems (EWOS) and

41、 the Asia-Oceania Workshop (AOW). This part of ISO/IEC ISP10607 is harmonized among these three Workshops and it was finally ratified by the Workshops plenary assemblies. 1 Scope 1.1 General This part of ISO/IEC ISP10607 (AFT22) covers access to files between the filestores of two end systems, using

42、 the OSI connection-mode transport service to provide the interconnection. One end system acts in the initiator role and requests access to the file, the other end system acts in the responder role and provides access to the file in the virtual filestore. These role combinations and the interoperabi

43、lity are shown in Table 1. Table 1 Interoperable configurations Access of files is supported for files with an unstructured, flat or random access constraint set and containing binary or character data. This part of ISO/IEC ISP10607 specifies implementations that support file transfer and file acces

44、s, i.e. the ability to a) read an FADU which is identified by node name, node number or by position (depending on constraint set and document type), b) write (replace and/or extend and/or insert, depending on constraint set and document type) to a file, and c) locate and erase within a file; and opt

45、ionally to a) create and delete a file, and b) read the attributes of a file. Grouping of actions is not mandatory. Therefore, the above file actions can be performed separately and also, multiple file actions can be performed within a given regime. This part of ISO/IEC ISP10607 specifies how the OS

46、I FTAM application standard shall be used to provide the functions defined above. It does not specify total system capability. In particular, a system may operate this profile and at the same time engage in other communications. The requirements placed on an implementation in this part of ISO/IEC IS

47、P10607 are solely those necessary for operation of the protocol specified. This part of ISO/IEC ISP10607 describes the actions and attributes of the virtual filestore, and the service provided by the file service provider to file service users, together with the necessary communications between the

48、initiator and the responder. 1.2 Position within the taxonomy This part of ISO/IEC ISP10607 is identified in ISO/IEC TR10000-2 as “AFT22Positional File Access Service (flat)”. It may be combined with any T-Profiles (seeISO/IEC TR10000) specifying the OSI connection-mode transport service. 1.3 Scenar
