Usage Advice
Use when
- Use for a measurement that yields an elapsed-time figure (years before present, sample age) rather than an absolute calendar date — the radiocarbon/geologic style of result.
Avoid when
- Avoid for an absolute calendar instant (use
gmeow:measuredDate, which feeds theperiodStartchain) and avoid omittinggmeow:hasUnit; a bare number without a unit is ill-formed.
How to use
- Write an xsd:decimal age and always pair it with
gmeow:hasUnit; record spread withgmeow:measurementUncertainty; converting an age to an absolute date is a solver-layer concern (P12), so age does not trigger theperiodStartchain.
