Future mobility poses new challenges for the innovative data-based services. Some examples are: route planning according to energy aspects or multimodal mobility services - sharing services, public transportation, taxis in complex environments. Development of such services requires integration of various data sources: e.g. map data, vehicle data, weather data, mobility service descriptions, events information, etc. These data sets often have proprietary data structures. The MobiVoc initiative MobiVoc intends to enable a data communication among all available data sources by providing a powerfyl vocabulary for modeling the mobility data.
