Motivating Scenario Sensors in USA Spatial information • Find all the sensors which have observations related to a blizzard occurring in Nevada on 24th August 2005 at 11 AM Thematic information Temporal information 4
PROVENANCE Spatial information • Find all the sensors which have observations related to a blizzard occurring in Nevada on 24th August 2005 at 11 AM Thematic information Temporal information PROVENANCE informationof the observation is required for SENSOR DISCOVERY PROVENANCE : History or Lineage of data entity 5

ProvenanceStorage GeoNames Dataset: Geographic dataset contaning information about countries and 8 million place names locatedNear Provenance Aware Linked Sensor Data Sensor Dataset Publicly Accessible Provenance Aware Sensor is adding provenance to Linked Sensor Data (on LoD). 11
Workflow Implementation Sensor Provenance Ontology MesoWest is a Project at University of Utah, Department of Meteorology that collects observations for ~20,000 sensors in United States Open Geo-Spatial Consortium standard (O&M) for encoding sensor descriptions and observations
Workflow Implementation Sensor Provenance Ontology • Virtuoso RDF store is an open source RDF triple store from Open Link software. • Currently contains 1.7 billion triples of sensor observational data Virtuoso RDF Store 13
Future Work • Implementing the motivating scenario • Implement provenance query operators • Create a plug-in implementation that can add provenance information to any processing of sensor dataset automatically 14
Conclusion • Developed an ontology-driven provenance management infrastructure for Sensor data called Sensor PMS • Developed a domain specific provenance ontology by extending the provenir ontology • Extension of standard ontology helps sharing and integration of provenance information across different domains 15
