4.1.9.2.1 Project Template Definitions

Declaration of property set templates, including the property templates that are used as property definitions. Such templates define the applicable properties, their names, descriptions, measure types and property type (single, enumerated, bounded list or table value).

The following diagram shows the generic classes and relationships used when applying this concept. In addition, concepts may have particular importance to common or standardised industry practices and scenarios. For these specific usage scenarios, the table below shows a recommended list of general usage patterns that users may adopt.
