Description	Geo-referenced data play an increasingly important role in many application areas. The result is a growing need for infrastructures that support the access and exchange of such data. Internet-based geodata servers and service-oriented geodata infrastructures focus on the exchange of GIS-type geodata, and require sophisticated server-side functionality. This prevents many small data providers from participating and hampers the exchange of directly- and indirectly geo-referenced data. The integration of peer-to-peer (P2P) technology may help to lower the barrier for participation. However, to support data retrieval based on complex spatial queries in such networks, condensed but expressive spatial metadata are needed. The paper outlines a concept for spatial metadata based on qualitative spatial reference models, and their application in P2P networks.
