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 representation of the input and output constructs necessay to support the representation of function based behavior.

FBB is based on the concept of function. Other descriptions of response rely on state descriptions. FBB does not use the concept of state. The concept of function is the transformation of a set of inputs into a set of outputs. In chemistry inputs of oxygen and hydrogen are transformed by chemical reaction to produce water and heat. An electric power generation station transforms chemical energy to heat energy, heat energy to mechanical energy, mechanical energy to electrical energy, and electrical energy to the correct voltage level synchronized with the power grid. The concept of transformation is basic to science and engineering. The word "Function" is not allowed as an entity name because of EXPRESS constraints. Instead the word "Transformation" is used as a synonym.

Several transformations may share a single resource such as bandwidth or computer memory. This module supports the entities needed to assess resource utilization by behavior execution.

NOTE: In the absence of a structure module set it is necessary to defer:

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.
