Linking Sensor Data – Why, to What, and How?

Keßler Carsten, Janowicz Krzysztof

Zusammenfassung

The Sensor Web provides access to observations and measurements through standardized interfaces defined by the Open Geospatial Consortium’s Sensor Web Enablement (SWE) initiative. While clients compliant to these standards have access to the generated sensor data, it remains partially hidden from other knowledge infrastructures building on higher-level W3C standards. To overcome this problem, it has been proposed to make sensor data accessible using Linked Data principles and RESTful services. This position paper discusses the embedding of such data into the Linked Data cloud with a focus on the outgoing links that hook them up with other data sources. We outline how such links can be generated in a semi-automatic way, and argue why curation of the links is required. Finally, we point to the query potential of such an additional interface to observation data, and outline the requirements for SPARQL endpoints.
