dev.sensorthings ยท 11- dev.sensorthings.datastream record Groups Observations of one ObservedProperty by one Sensor on one Thing. Carries all context needed to interpret observation results.
- dev.sensorthings.featureOfInterest record The real-world feature that an Observation is about.
- dev.sensorthings.multiObservation record A composite observation bundling multiple co-produced results from a single act of sensing. Each entry carries its own ObservedProperty, unit, and scale metadata. Use this instead of separate Observations when the results are genuinely co-produced (e.g. wave statistics from spectral processing) and have no independent existence.
- dev.sensorthings.observation record A single act of observation. The result type is determined by the $type discriminator on the result object.
- dev.sensorthings.observationBatch record A batch of observations for a single Datastream, covering a contiguous time window. Trades individual addressability for reduced commit overhead.
- dev.sensorthings.observationFrame record The new or changed readings from one collector tick, for many Datastreams in the same repo. Created once and never updated. After the correction horizon has passed, the readings are sealed into dev.sensorthings.observationBatch day records and the frame is deleted. Apply frames in record key order: a later entry for the same datastream and phenomenonTime replaces an earlier one. The record key is the tick time to the millisecond and a three-digit shard number, for example 20260925T100700000Z-000
- dev.sensorthings.observedProperty record The phenomenon being observed (e.g. air temperature, PM2.5 concentration).
- dev.sensorthings.operator record Roster entry for an approved sensor-network operator. Our attestation that an operator was admitted, under a stated open licence, at a stated time. Held in a central registry repo we control, not in the operator's own data repo, so a sovereign operator cannot rewrite their own admission status. Carries org-level facts only; contact details and operational configuration are kept in the private moderation store, not on this public record.
- dev.sensorthings.quality defs Observation passed QC checks.
- dev.sensorthings.sensor record An instrument or procedure that produces observations.
- dev.sensorthings.thing record A physical object (station, platform, device) capable of hosting sensors.
