LinkSmart® Historical Datastore (HDS) is a modular service for time-series data storage. This service is designed to store timeseries data on low power devices and single board computers and to accept data from constrained devices. HDS uses Sensor Measurement Lists (SenML) as the data format for storage and retrieval. Metadata related to the data is also stored in HDS using registry API.
A full-implementation of HDS offers two APIs:
Registry API : Submission, retrieval and updation of meta-data for sensor measurements.
Data API : Submission and retrieval of sensor measurements.
