Licensing OGC Geoprocessing Services as a Foundation for Commercial Use in SDIs

This paper presents an approach for enabling the commercial use of OGC Web Processing Services (WPS) in Spatial Data Infrastructures. In particular, it demonstrates how WPS can be enhanced for ad-hoc license agreements without any prior offline negotiation between geoprocess provider and geoprocess user. A security-enabled architecture including the components and their interactions is described. Additionally, a classification of potential licenses for Geoprocessing Services is provided. These licenses are based on dynamic negotiation of access rights and are in contrast to classical role-based access control. Finally, the presented ideas are implements as a proof-of-concept for a real world scenario.
