The development of the next major version of CityGML will officially be commenced at next OGC Technical Committee meeting in Geneva, Switzerland, on 11 June 2014. The overall work scope for CityGML 3.0 will include changes to CityGML’s level-of-detail concept, additional semantic model structures such as building storeys, floor plans and utility networks, as well as new complex attributes such as time series and metadata.
The OGC seeks organizations and individuals to participate in the development of the next version. Responses to the Call for Participation are requested by 10 June 2014, but participation is also possible after this deadline, since the Call for Participation will remain open for the whole duration of the CityGML 3.0 development process.

The Chair of Geoinformatics will actively participate in the development of CityGML 3.0. The focus of the chair’s participation will be on developing a representation for changing content of entire models or parts of a model which includes time-sequences of successive representations, simultaneously existing alternate versions, mobile objects, and dynamic objects.
