Cross-IoT Study of the Characteristics of IoT Schemata and Data Streams

Eugene Siow

A broad cross-IoT study of the characteristics of Things schemata and data streams. The aim of the study is to determine the flatness, width, types of attribute values and periodicity of current IoT data streams from various domains and use cases.

There are individual README.md files describing each of the datasets and the files within the dataset in more detail.

Studies:

  • SparkFun: 614 schemata of devices in Jan 2016 : Folder /sparkfun/
  • ThingSpeak: 9033 schemata of devices in July 2017 : Folder /ThingSpeak/
  • Array of Things: 9033 schemata of devices in July 2017 : Folder /array_of_things/
  • OpenEnergyMonitor EmonCMS: 9033 schemata of devices in July 2017 : Folder /EmonCms/
  • Open Humans: HealthKit, Fitbit, RunKeeper and Move schemata in July/August 2017 : Folder /OpenHumans/
