End-to-End Semantics for Sensor Net 2.0

• Semantic sensor data models
• Ontologies as meta-data
• Tools SensorML, OWL or RDF(S)
• Sensor data as instances of ontological concepts
• Semantic sensor meta-data reconciliation
• Ontology mapping and merging
• Current research maturing
• Facilitates publication and querying of disparate
  sensor data
• Transfer sensor data across reconciled ontologies
• Semantic querying and data integration
• Query instances and meta-data
• Tools SPARQL for RDF data
• Facilitates meaningful data fusion
