Idtimestampvalueunit
Idtimestampvalueunit is a compact data record schema used to store a measured quantity along with its identifier, the time of measurement, and the unit of the value. It is commonly applied in time-stamped logging, telemetry, and data interchange for sensors and experiments.
The four fields are typically defined as follows:
- id: a unique identifier for the record, often a UUID or numeric primary key. It enables unambiguous
- timestamp: the moment the measurement was taken. Standards often favor ISO 8601 formatted strings or epoch
- value: the numeric measurement itself. This can be an integer or floating-point number, and precision should
- unit: a string describing the measurement unit (for example, "C" or "°C" for Celsius, "m" for meters).
Typical uses include recording sensor readings, experimental results, or events where a numeric quantity is observed
Example: a record with id "a1b2c3", timestamp "2024-07-01T14:23:00Z", value 42.7, unit "°C" represents a measured temperature
Variants may omit the id, use composite keys, or store units separately for normalization. The idtimestampvalueunit
