4、etworking permitted without license from IHS-,-,-INTERNATIONAL STANDARD IS0 / IEC 10031-l :1991(E) Information technology-Text and office systems - Distributed-office-applications model - Part 1: General model 1 Scope ISO/IEC 10031 provides a framework for the purpose of the development of protocol
5、standards for distributed-office-applications (DOAs). It applies to applications distributed over significant physical distances as well as “closely-coupled” office systems. ISO/IEC 10031 describes a model. Distributed-office-applications to be standardized shall use the principles specified in it.
6、ISO/IEC 10031 provides guidelines for the design of protocols which allow access to the various applications and ;,lberactions between applications. The protocols for distributed applications are within the OS1 Application Layer and conform to the Remote Operations defined in ISO/IEC 9072. ISO/IEC 1
7、0031 embraces the intent that elements of a system conforming to some parts of it can be implemented from devices supplied by different vendors and by different service providers. ISO/IEC 10031 does not define human-machine interfaces used with the distributed-applications. Also, it does not define
8、the interface between the software that interacts directly with the user and the software of specific applications. The content of ISO/IEC 10031 is comprised of two parts. This part of ISO/IEC 10031 describes the general model of distributed-office-applications and is divided into two sections: a) m
9、odel ; b) guidelines for the design of DOA protocols. ISO/IEC 10031-2 describes the Distinguished-object-reference and associated procedures that may be used by all DOAs. No requirement is made for conformance to this part of ISO/IEC 10031. Other parts of ISO/IEC 10031 may specify conformance for sy
10、stems implementing procedures of those other parts. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part of ISO/IEC 10031.
