Status

Local, because neither CF nor ODM2 has the term, and owed upstream to ODM2. Its durable identifier will be a w3id.org address that redirects here (Q4c), so links to this page keep working.

Scope note

A genuine gap. CF names physical quantities and has no term for an actuator's state; the nearest it has, surface_downward_mass_flux_of_water_due_to_irrigation, is a rate of water, which a valve's state is not. ODM2 has water pumped for agriculture, a volume, but nothing for whether a valve stood open. A controller reports exactly this, opening and closing (OpenSprinkler over MQTT, docs/notes/irrigation-projects.md), and the watering check needs it to tell a blocked drip line from a bed nobody watered. To be published upstream to ODM2 with vessel_fill_fraction.
