LinkSmart® Historical Datastore (HDS) is a modular service for time-series data storage. The service is intended to have multiple implementations using different backends offering varying degrees of the implemented functionality. Different implementations may accept incoming sensor data in different data formats, as well as support multiple formats simultaneously. All implementations support SenML data model and may offer additional formats using HTTP negotiation.
A full-implementation of HDS offers three APIs:
Registry API : Registry of sensor meta-data and details regarding sensor data storage and aggregation
Data API : Submission and retrieval of raw sensor measurements
Aggregation API : Retrieval of aggregated sensor measurements
