Dataset: officegraph (development version)

OfficeGraph is a real-world dataset of measurements from 444 IoT devices taken over 11 months. The devices are made up of 17 different sensor models which measure different properties. The data was collected in a Dutch 7-story office building and consists of about 90 million RDF triples. See also the paper for more details.

The elements in the dataset are ordered from oldest to newest by the measurement time (saref:hasTimestamp predicate).

Additional data such as the metadata about the devices taking measurements and rooms in the building, as well as copy of this dataset can be found on Zenodo.

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.
