Recently, a number of car companies focus on collecting and analyzing data from connected car to provide accurate and variety of integrated information services to users. To provide integrated connected car services, however, there are still two main problems in existing systems. First, there are not well-defined standard car-related data models for data sharing which is basic prerequisite of integrated service. Second, each company stores the data to the closed server and blocks the access so that the data is available only inside the respective data silos. Because of these reasons, it is hard to combine various data to provide integrated information service. To solve the problems, we propose two solutions. 1) Define events of the car life cycle, and data models for data sharing. 2) Establish open system for data sharing and service registration based on GS1 standard. Upon proposed models and system, we have implemented an example service, traffic light control, as a third party service to show the feasibility of our system. Therefore, this research enables to provide open system to car companies and third party service providers to make services associated with the connected car.
