Main Outcomes (I)<br />System Level (WP1)<br />An architecturefor the design and implementation of open large-scale Semantic Sensor Grids.<br />A reference SemsorGrid4Env implementation instantiating the architecture<br />Component-level (WP2-WP5):<br />New techniques and tools for semantic-based data management over the heterogeneous data streams that stem from autonomously deployed sensor networks. (WP2)<br />Scalable and fault-tolerant resource discovery mechanisms for sensor registries. (WP3)<br />The semantic infrastructure (including ontologies) needed to facilitate the integration of data coming from heterogeneous and distributed sensor networks, legacy databases and applications. (WP4)<br />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)<br />Two environmental management applications (WP6-WP7)<br />5<br />EGU 2010 - Vienna, 6 May 2010<br />

Main Project Phases<br />9<br />EGU 2010 - Vienna, 6 May 2010<br />
WP1: SSG4Env General Architecture<br />Properties:<br /><ul><li>Any service may directly call any other service.
Pre-existing services may be called by any service.
Documented requirements from use cases, to the level of queries and data analyses.
Support QoS-aware evaluation within in network query optimizer.
Developed out-of-network query compiler and evaluator from to support integration queries.</li></ul>SELECT RSTREAM t.id, w.speed, w.dirn<br />FROM wind[NOW] w, tree[NOW] t<br />WHERE t.smoke > 0<br />AND sqrt((t.locx - w.locx)^2 + <br /> (t.locy - w.locy)^2) <= 40<br />EGU 2010 - Vienna, 6 May 2010<br />11<br />
WP3: Semantic Registry<br /><ul><li>Defined the data model stRDF and the query language stSPARQL, based on the paradigm of constraint databases.
Represent thematic and spatial metadata that change over time. Coupled with the RDFS/OWL ontologies of WP4.
Developed a formal semantics and algebra for stSPARQL on which we base our implementation.
Development of Strabon: a centralized implementation of a subset of stSPARQL.</li></ul>EGU 2010 - Vienna, 6 May 2010<br />12<br />
WP4: Semantic Infrastructure<br /><ul><li>Designed, implemented and deployed a Semantic Integration Service
Extend existing ontology-based data integration models to take into account sensor networks streaming data, semantic heterogeneity and quality of service
Specified a suite of sensor network ontologies that will be used for describing sensors and related data for the SemSorGrid4Env software architecture </li></ul>EGU 2010 - Vienna, 6 May 2010<br />13<br />
