Short paper: Collaboration between VANET applications based on open standards

As of today, there is a variety of self-contained vehicular ad hoc network (VANET) applications. In many scenarios, they could complement each other if they would allow for interoperability. However, since they often use different data formats and do not share a common, machine-readable and platform-independent definition of terms and semantics, they cannot mutually understand and reuse each other's data. Consequently, in this paper we propose a VANET Ontology (VO) for defining the semantics of VANET relevant terms and a common VANET Data Representation (VDR) to facilitate interoperability between arbitrary VANET applications.
