What is FROST?
The FRaunhofer Opensource SensorThings-Server (FROST) is an implementation of the OGC SensorThings API. It can be deployed as a Docker image, or directly on an existing Tomcat or similar server. Since version 2 it has a flexible data model implementation that allows the data model to be extended or even completely replaced with little effort. This makes FROST an ideal platform for data model experiments.
For the GeoTech IE a plugin has been made for FROST that extends the STA core data model with extra entities. See FROST plugin for Geotech.
More details can be found at the FROST GitHub page or the FROST Documentation site.
