9、urther parts be published, they will follow the same numbering pattern. Annex A forms an integral part of this part of IS0 10303. Annex B is for information only. IS0 IS0 10303-1:1994(E) Introduction The information generated about a product during its design, manufacture, use, maintenance, and disp

10、osal is used for many purposes during that life cycle. The use may involve many computer systems, including some that may be located in different organizations. In order to support such uses, organizations need to be able to represent their product information in a common computer-interpretable form

11、 that is required to remain complete and consistent when exchanged among different computer systems. IS0 10303 is an International Standard for the computer-interpretable representation and ex- change of product data. The objective is to provide a mechanism that is capable of describing product data

12、 throughout the life cycle of a product, independent from any particular system. The nature of this description makes it suitable not only for neutral file exchange, but also as a basis for implementing and sharing product databases and archiving. IS0 10303 is organized as a series of parts, each pu

13、blished separately. The parts of this Interna- tional Standard fall into one of the following series: description methods, integrated resources, application protocols, abstract test suites, implementation methods, and conformance testing. This part of IS0 10303 provides an overview. It specifies the

14、 functions of the various series of parts of IS0 10303 and the relationships among them. vii INTERNATIONAL STANDARD ISO IS0 10303-1:1994(E) Industrial automation systems and integration - Product data representation and exchange - Part 1 : Overview and fundamental principles 1 Scope This part of IS0

15、 10303 provides an overview of this International Standard. This International Standard provides a representation of product information along with the necessary mechanisms and definitions to enable product data to be exchanged. The exchange is among different computer systems and environments assoc

16、iated with the complete product lifecycle, including product design, manufacture, use, maintenance, and final disposition of the product. The following are within the scope of IS0 10303: - the representation of product information, including components and assemblies; - the exchange of product data,

17、 including storing, transferring, accessing, and archiving. This part of IS0 10303 defines the basic principles of product information representation and exchange used in IS0 10303. It specifies the characteristics of the various series of parts of IS0 10303 and the relationships among them. The fol

18、lowing are within the scope of this part of IS0 10303: - an overview of this International Standard; - the structure of this International Standard; - definitions of terms used throughout this International Standard; - an overview of data specification methods used in this International Standard inc

19、luding the EXPRESS data specification language and graphical presentation of product information models: - an introduction to the integrated resources; - an introduction to application protocols that are used to define the scope, context, and information requirements of an application, and the repre

20、sentation of the application information; - an introduction to the methodology and framework for conformance testing that pro- vides an assessment of whether an implementation conforms to this International Standard; 1 IS0 10303-1:1994(E) 0 c IS0 - an introduction to the abstract test suites to be u

21、sed as a basis for conformance testing; - an introduction to the implementation methods which may be used with this Interna- tional Standard. The scopes of the other parts of IS0 10303 are defined within those parts. 2 Normative references The following standards contain provisions which, through re

27、t describes an application in terms of its processes and information flows. 3.2.4 application context: the environment in which the integrated resources are interpreted to support the use of product data in a specific application. 3.2.5 application interpreted model (AIM): an information model that

28、uses the integrated resources necessary to satisfy the information requirements and constraints of an application ref- erence model, within an application protocol. 3.2.6 application object: an atomic element of an application reference model that defines a unique concept of the application and cont

29、ains attributes specifying the data elements of the object. 3.2.7 application protocol (AP): a part of this International Standard that specifies an ap- plication interpreted model satisfying the scope and information requirements for a specific application. NOTE - This definition differs from the d

30、efinition used in open system interconnection (0%) stan- dards. However, since this International Standard is not intended to be used directly with OS1 communications, no confusion should arise. 3.2.8 application reference model (ARM): an information model that describes the infor- mation requiremen
