A RESTful Proxy and Data Model for Linked Sensor Data

The vision of a Digital Earth calls for more dynamic information systems, new sources of information and stronger capabilities for their integration. Recent developments in sensor networks have been identified as a central building block. So far, sensor data is stored and published using the Observations & Measurements standard of the Open Geospatial Consortium (OGC) as data model. With the advent of Volunteered Geographic Information and the Semantic Sensor Web, work on an ontological model gained importance within Sensor Web Enablement (SWE). In contrast to data models, an ontological approach abstracts from implementation details by focusing on modeling the physical world from the perspective of a particular domain. Ontologies restrict the interpretation of vocabularies towards their intended meaning. The ongoing paradigm shift to Linked Sensor Data requires yet another perspective. Two questions have to be addressed: (i) how to refer to changing and frequently updated data sets using Uniform Resource Identifiers, and (ii) how to establish meaningful links between those data sets, i.e., observations, sensors, features of interest, and observed properties? In this paper, we suggest a Linked Data model and develop a RESTful proxy for OGC's Sensor Observation Service to request Linked Sensor Data for the Digital Earth.
