work_requirement ISO 10303-239 Representation

The business objects introduced in the Business Information Overview section are modelled in PLCS through a set of business templates. Most business templates are based upon one or more generic PLCS templates. They may be specializations of a PLCS template using one or more classifications or characterizations to capture the required information, whilst some rename and use restricted parameters.

A diagramtic representation of the AP239 templates used is shown below in Figure 2.
Please note that to improve understanding of the diagram, not all of the templates referenced in the table are shown.

This section summarizes the mappings of the business objects to the corresponding templates.
