SIRI-ET is used to model the status of existing journeys and to ensure that deviations from the planned data (for the same operating day) such as cancellations, additional departures, delays, detours and changes in stops, can be published on short notice. The data should be linked to objects in the planned data through matching ids.

Structure

The root element estimatedTimetableDeliveryStructure includes a response timestamp (when the XML structure was rendered), subscriptionRef in case publish/subscribe is used for the data transfer, and exactly 1 one EstimatedJourneyVersionFrame.

EstimatedJourneyVersionFrame contains a recorded timestamp RecordedAtTime, which is the time at which the source data was updated, along with one or more EstimatedVehicleJourney elements detailing deviations for one trip each.

The tables below list which fields are supported by Samtrafiken. Any fields or attributes not on the list are ignored.

Element	Required	Notes
RecordedAtTime	Required	Timestamp, e.g. 2024-11-12T14:26:37+01:00
EstimatedVehicleJourney	Required	One or more estimated vehicle journeys, see below
