Definition |
An instance of this DRM class is a <DRM Aggregate Feature> instance containing a collection of <DRM Feature Representation> instances. The union_reason field specifies the reason why the <DRM Union Of Features> instance was created to organize its components. The ordering_reason field specifies whether the ordering of the <DRM Feature Representation> components of the <DRM Union Of Features> instance is semantically significant and, if so, what that significance is. |

Clarifications |
1An association between two <DRM Feature Representation> instances indicates that the environmental object(s) that they represent have the semantic relationship indicated by the <DRM Base Association Data> link object on the association relationship. 2An association between a <DRM Geometry Hierarchy> instance and a <DRM Feature Representation> instance indicates that the environmental object(s) that they represent have the semantic relationship indicated by the <DRM Base Association Data> link object on the association relationship. 3An association between a <DRM Property Grid> instance and a <DRM Feature Representation> instance indicates that the environmental object(s) represented by the <DRM Feature Representation> instance and the <DRM Property Grid> instance (or some specific cell data within that <DRM Property Grid> instance) have the semantic relationship indicated by the <DRM Base Association Data> link object on the association relationship. Each associated <DRM Property Grid> instance indicates whether the entire <DRM Property Grid> instance or only some specific cell data within it is participating in the relationship in question. 4An association between two <DRM Feature Representation> instances indicates that the environmental object(s) that they represent have the semantic relationship indicated by the <DRM Base Association Data> link object on the association relationship. 5An association between a <DRM Geometry Hierarchy> instance and a <DRM Feature Representation> instance indicates that the environmental object(s) that they represent have the semantic relationship indicated by the <DRM Base Association Data> link object on the association relationship. 6An association between a <DRM Property Grid> instance and a <DRM Feature Representation> instance indicates that the environmental object(s) represented by the <DRM Feature Representation> instance and the <DRM Property Grid> instance (or some specific cell data within that <DRM Property Grid> instance) have the semantic relationship indicated by the <DRM Base Association Data> link object on the association relationship. Each associated <DRM Property Grid> instance indicates whether the entire <DRM Property Grid> instance or only some specific cell data within it is participating in the relationship in question. 7The <DRM Image Mapping Function> components support texture mapping information for geometry that is to be derived from the <DRM Aggregate Feature> instance by the consumer. These <DRM Image Mapping Function> instances shall use <DRM Image Anchor> components to specify the mapping. 8A <DRM Presentation Domain> component is needed for <DRM Aggregate Feature> instances that are significant only for a particular domain, such as radar. |
