1. SemSorGrid4Env: Semantic Sensor Grids for Rapid Application Development for Environmental Management www.semsorgrid.eu Development of an integrated information space where new sensor networks can be easily discovered and integrated with existing ones and possibly other data sources Rapid development of flexible and user-centric decision support systems that use data from multiple autonomous independently deployed sensor networks and other applications.

8. Summary From application perspective there are many different kinds of users Apps need to find data sources, (s)mash them up, and use live data Priority-push and adaptive sampling are important Semantics support discovery of sources, integration of information, publishing, annotation, provenance, automation Architecture-Data model interplay: mashups over SOA and publishing linked data for reuse
