15. Use data from multiple autonomous independently deployed sensor networks and other applications.4 EGU 2010 - Vienna, 6 May 2010
16. Main Outcomes (I) System Level (WP1) An architecturefor the design and implementation of open large-scale Semantic Sensor Grids. A reference SemsorGrid4Env implementation instantiating the architecture Component-level (WP2-WP5): New techniques and tools for semantic-based data management over the heterogeneous data streams that stem from autonomously deployed sensor networks. (WP2) Scalable and fault-tolerant resource discovery mechanisms for sensor registries. (WP3) The semantic infrastructure (including ontologies) needed to facilitate the integration of data coming from heterogeneous and distributed sensor networks, legacy databases and applications. (WP4) Higher-level application programming interfaces that ease the rapid generation of thin applications (e.g., mashups) of data from sensor networks and historical databases. (WP5) Two environmental management applications (WP6-WP7) 5 EGU 2010 - Vienna, 6 May 2010
