Dataset: assist-iot-weather-graphs (development version)

This is a timestamped stream of weather data collected with a Davis Vantage Pro 2 weather station installed on the building of the Systems Research Institute, Polish Academy of Sciences. The data was collected during the ASSIST-IoT Horizon 2020 project. The station measured several different weather parameters and transmitted them in real time at regular intervals. The measurements have rich annotations with the SOSA/SSN and OM 2.0 ontologies. The stream is very regular and the elements only differ by numeric values and timestamps. This is the graph variant, which is a timestamped graph stream compatible with the RSP Data Model.

The dataset is a real application of RDF streaming (originally streamed over MQTT), with much richer annotations than citypulse-traffic. On the other hand, it is perfectly regular, with no differences in structure between stream elements.

This README is a snapshot of documentation for the latest development version of the dataset. Full documentation for all versions can be found on the website.
