Weather with SOSA/SSN ontology

This RDF dataset is an open archive of measurements generated by one of the meteorological stations that Irstea owns in its experimental farm at Montoldre. These measurements were collected between january and december 2017. It uses the new Semantic Sensor Network Ontology, called (and prefixed) sosa. We also reused some specific ontologies:

  • The unit are described by the QUDT ontology.
  • The sensor are described by the AWS ontology.
  • The location of the weather station is described by the LOCN vocabulary and the geosparql ontology.

This was done for the same station with data callected from years 2010 to 2015, using the old Semantic Sensor Network Ontology. The old dataset is available at here.
