Abstract: . In this paper a concept for storing validation information in CityGML as an extension is proposed. This work is an extension of our previous work in which we improve and evaluate more of the validation process and the data storage itself (Betz and Coors, 2021). With this model companies, states and municipalities can manage the quality of their 3D models based on CityGML more easily. The information can be further used in other application software to improve their handling of imperfect 3D models as their input. Without quality information it is almost always unknown whether an issue stems from a problem in their application or from errors in the input data itself. CityGML creators can now distribute CityGML files with the quality information contained in them providing a standardized way of storing the data alongside the 3D models. The quality management information also further improves the process of 3D data creation. As issues are detected with a proper quality management tool and stored in the data, the validation information can be used to find problems in the workflow and remove them.
