The log line itself.
OptionalauthorCrew member the line is attributed to. Free text, not an audit identity: delegation is a feature.
OptionalcategoryEntry category. Open enumeration; the recommended vocabulary is
navigation, engine, radio and maintenance.
OptionaldatetimeRFC 3339 UTC datetime of the entry, the chronological sort key. Defaults to now on create and is preserved on replace.
OptionalidEntry UUID. Equals the resource id; the resource id is canonical.
OptionaloriginHow the line came to be. Open enumeration; the recommended vocabulary
is manual (typed in a UI), auto (trigger/hourly/notification) and
agent (machine writing on behalf of a human).
OptionalpositionVessel position at the entry datetime. Entries not anchored to a place
omit it; telemetry may additionally carry a navigation.position
snapshot of the same moment. Storage only: the standard listing API
defines no spatial query.
OptionalschemaReserved for future revisions of the entry schema; absent = 1. Other writers must not use the name for anything else.
OptionaltelemetrySnapshot of Signal K paths observed at the entry datetime.
A log entry resource — a line in the vessel's logbook, time-anchored by
datetimeand optionally place-anchored byposition, carrying an optional snapshot of Signal K paths observed at that moment. Open content model: consumers must ignore unknown fields and providers must preserve them on write; extension fields should be namespaced by the writing application (e.g.x-stylusapp-ink).
