3.0.0-draft.2019.10.18.1

This is a new release of the draft OGC CityGML 3.0 Conceptual Model.

Notable changes and additions

• Moved attribute surfaceMaterial from TrafficSpace/AuxiliaryTrafficSpace to TrafficArea/AuxiliaryTrafficArea. #78
• Class ImplicitGeometry: made attribute transformationMatrix mandatory. #73
• Added class, function, and usage to Door and Window. #76
• Changed composition between AbstractBuilding and AbstractBuildingSubdivision to aggregation. #71
• Introduced the abstract classes AbstractAppearance, AbstractDynamizer, AbstractGenericAttribute, AbstractPointCloud, AbstractVersion, and AbstractVersionTransition to remove dependencies of the Core module to the thematic modules Appearance, Dynamizer, Generics, PointCloud, and Versioning. #68
• Added code list classes to every module. #10
• Corrected OCL constraint of the class PointCloud. #91
• Added a lod0MultiSurface geometry property to AbstractThematicSurface. #92
• Change stereotype of ImplicitGeometry from <<FeatureType>> to <<ObjectType>>. #86
• An association from CityObjectRelation to AbstractGenericAttribute was defined in the Core module. This allowed for removing the class GenericCityObjectRelation in the Generics module. #80
• The association between AbstractSpace and AbstractThematicSurface was made uni-directional. In the thematic modules Construction, Building, Transportation, and WaterBody, the subsets of the bounds-boundary relation were replaced by the original bounds-boundary relation. In this way, no additional relationships are derived in the GML application schemas. #21
• Changed sequence of properties in core:AbstractSpaceType. #22
