Abstract. CityGML is an international standard issued by the Open Geospatial Consortium (OGC) for representing and exchanging Semantic 3D City Models. Due to their large scale and deeply nested structures, the management and visualization of CityGML based models require sophisticated solutions such as the 3D City Database (3DCityDB). The research work presented in this article proposes a high level architecture for extending the 3D City Database to store and manage dynamic properties encoded within a new Application Domain Extension (ADE) of CityGML called Dynamizer ADE. The implementation employs the 3DCityDB 4.2 ADE Plugin Manager, which provides an automatic way for dynamically extending the 3DCityDB to support the storage and management of CityGML models with ADEs. The paper introduces a relational database model for storing and managing the Dynamizer ADE within the 3DCityDB. Further, the research work includes the extension of the 3DCityDB Importer/Exporter in order to import and export CityGML documents including Dynamizer ADE data. 3DCityDB already comes with a Web Feature Service (WFS) interface allowing CityGML features to be requested in standardized ways. The proposed framework enables CityGML Viewers to access static data (using OGC WFS interface) and dynamic data (using the OGC SWE interfaces) in an integrated fashion.
