Introduction

ISO 10303 is an International Standard for the computer-interpretable representation of product information and for the exchange of product data. The objective is to provide a neutral mechanism capable of describing products throughout their life cycle. This mechanism is suitable not only for neutral file exchange, but also as a basis for implementing and sharing product databases, and as a basis for retention and archiving.

This part of ISO 10303 specifies an application module for the representation of data that records the identification of an existing or potential future artefact - an actual product whose properties can only be known by observation or by derivation from observations.

It is likely, but not essential, that the artefact, was or will be made from a version of a product design, which will be represented by the Product identification, Product version and Product view definition modules. The artefact will be represented by a Product_as_individual entity.

A revision made to the artefact is represented by a sub type of the entity Product_as_individual_version namely Product_as_planned or Product_as_realized.

A revision of an actual product that has been made is represented by a Product_as_realized entity.

A revision of a product that is planned to be made is represented a Product_as_planned entity.

EXAMPLE 1   The front wheel on your car is an actual product - Product_as_realized.

EXAMPLE 2   The computer with the serial number "PN X0467-71281" is an actual product - Product_as_realized.

EXAMPLE 3   The plane, with tail number "GXY 8910", ordered by "Air 3000" that is just about to be manufactured is a predicted product - Product_as_planned.

This fourth edition of this part of ISO 10303 incorporates the modifications to the third edition listed in Annex F.4.

Clause 1 defines the scope of the application module and summarizes the functionality and data covered. Clause 3 lists the words defined in this part of ISO 10303 and gives pointers to words defined elsewhere. The information requirements of the application are specified in Clause 4 using terminology appropriate to the application. A graphical representation of the information requirements, referred to as the application reference model, is given in Annex C. Resource constructs are interpreted to meet the information requirements. This interpretation produces the module interpreted model (MIM). This interpretation, given in 5.1, shows the correspondence between the information requirements and the MIM. The short listing of the MIM specifies the interface to the resources and is given in 5.2. A graphical representation of the short listing of the MIM is given in Annex D.

In ISO 10303, the same English language words can be used to refer to an object in the real world or concept, and as the name of an EXPRESS data type that represents this object or concept.

The following typographical convention is used to distinguish between these. If a word or phrase occurs in the same typeface as narrative text, the referent is the object or concept. If the word or phrase occurs in a bold typeface or as a hyperlink, the referent is the EXPRESS data type.

The name of an EXPRESS data type can be used to refer to the data type itself, or to an instance of the data type. The distinction between these uses is normally clear from the context. If there is a likelihood of ambiguity, either the phrase "entity data type" or "instance(s) of" is included in the text.

Double quotation marks " " denote quoted text. Single quotation marks ' ' denote particular text string values.
