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 the information needed to describe the different aspects of how components are joined together to make an assembly. This module defines the information needed to describe the material used in making the physical connections and their typical shape. This module is foundational for verification and validation that the actual design meets detailed functional specifications by providing a mechanism for a design organization to make explicit assertions about the detailed joints that are implemented in the physical design.

NOTE 1   The current edition of this part of ISO 10303 supports predefined bond shapes. Bond material whose shape is defined in place can be represented using the capabilities of ISO/TS 10303-1032:2006.

NOTE 2   Joints that are asserted to be present in the design are mechanical views of the realized design at a detailed level.

EXAMPLE 1   A connector that is placed in an assembly using a coordinate transformation is a geometric representation of the relationship between the connector as a whole and the assembly it is helping to compose. The transformation makes no assertions about the detailed relationships between the features of the connector and the other item or items in the assembly that it is mated with during the assembly realization process. This module provides the ability to assert the relationship of each feature of that connector to a corresponding feature on a printed circuit board. A application may use that set of asserted relationships to verify the connector actually connects what it is intended to connect.

EXAMPLE 2   This module may be used to support the case where two daughter boards plug into a mother board to validate that the physical arrangment is a valid realization of the functional requirements for signal flow throughout the board set.

EXAMPLE 3   The Application objects in this module may be used as part of a query for a function that validates that a footprint associated with a specific component whose reference designation is U33 is the correct footprint.

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.
