4 Information requirements

This clause specifies the information requirements for the Distribution mapping application module.

The information requirements are specified as a set of units of functionality, application elements, and application assertions. These assertions pertain to individual application entities and to relationships between application entities. The information requirements are defined using the terminology of the subject area of this application module.

1. - A graphical representation of the information requirements is given in annex C.
2. - The mapping specification is specified in 5.1 which shows how the information requirements are met using the integrated resources of this International Standard. The use of the integrated resources introduces additional requirements which are common to application modules and application protocols.

4.1 Units of functionality

This subclause specifies the units of functionality (UoF) for the Distribution mapping application module as well as any support elements needed for the module definition. This part of ISO 10303 specifies the following units of functionality:

• Distribution_mapping.

This part of ISO 10303 uses the following units of functionality:

• Maths_function;
• Product_activity_and_state_space_mapping;
• Property_distribution;
• Scale.

The units of functionality and a description of the functions that each UoF supports are given below.

4.1.1 Distribution_mapping

The Distribution_mapping UoF specifies:

• the use of a mathematical function to describe a property distribution with respect to space or time;
• the use of a mathematical function to describe the relationship between two different parameterisations of a product, activity or state space;
• the use of a mathematical function to describe the relationship between two different scales of measurement.

The following application objects are used by the Distribution_mapping UoF:

• Distribution_domain;
• Identification_of_property_distribution;
• Parameterisation_mapping;
• Scale_mapping.

4.1.2 Maths_function

This UoF is defined in the Maths_function module. The following application entities from this UoF are referenced in the Distribution mapping module:

• Maths_function.

4.1.3 Product_activity_and_state_space_mapping

This UoF is defined in the Product_activity_and_state_space_parameterisation module. The following application entities from this UoF are referenced in the Distribution mapping module:

• Parameterisation.

4.1.4 Property_distribution

This UoF is defined in the Property_distribution module. The following application entities from this UoF are referenced in the Distribution mapping module:

• Property_distribution.

4.1.5 Scale

This UoF is defined in the Property_identification module. The following application entities from this UoF are referenced in the Distribution mapping module:

• Scale.
