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 archiving.

This part of ISO 10303 specifies an application module for the identification of selected items, that is items of hardware or software (or combinations of both hardware and software) and their associated Product Configuration Information for which there is a configuration management concern.

Selected items provide the basic units by which Configuration Management (CM) of the product is achieved.

Examples of different classes of selected items are:

EXAMPLE 1   Time Change/Shelf Life Selected Item (TCSI/SLSI) - All items that must be replaced at specific intervals or that have an elapsed time-related shelf life, are designated as TCSIs or SLSIs, as appropriate. These items do not require the rigorous, up-front CM activity (for example FCA/PCA but rather, they concentrate on the post-delivery CM aspects related to traceability in the field. This is commensurate with their emphasis on being changed/replaced at certain times.

EXAMPLE 2   Maintenance Selected Item (MSI) - Certain items whose maintenance requirements dictate a more detailed traceability than normal items, may be designated as MSIs. MSIs emphasize post-delivery traceability for maintenance purposes.

EXAMPLE 3   Support Equipment Selected Item (SESI) - Certain support equipment items that require some additional traceability, but do not require up-front CM activity are designated as SESIs. These items typically require traceability by lot or batch, but not by individual item serial number.

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 this International Standard, the same English language words may 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 may 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.
