About The Project

This is an implementation of the OGC SensorThings API Part I: Sensing.

Primary features:

  • Interoperability with the 52°North SOS and 52°North Helgoland API based on a shared data model (Contact us for further information about this feature)
  • Several convenience extensions
    • User-defined @iot.id
    • Extended MQTT Capabilities
    • Automatic synchronization of Datastream->phenomenonTime with linked Observation->phenomenonTime
    • etc.

Further documentation:

Roadmap

All development is tracked via GitHub Projects here.

Next Key Milestones:
