  • basedOnTemplate: reference to a template train detection element/system (optional; xs:string; patterns: (urn:uuid:)?[0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{12}|\{[0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{12}\}),

  • detectedObject: object (usually component of the railway vehicle) that is detected by the train detector (optional; xs:string)
Possible values:
  • axle
  • endOfTrain
  • train
  • wheel,

  • detectorMedium: medium (physical principle) that is used for detection by the train detection element (optional; xs:string)
Possible values:
  • hydraulic
  • inductive
  • magnetic
  • mechanical
  • optical
  • pneumatic
  • radio,

  • layout: constructional layout of the train detection element (optional; xs:string)
Possible values:
  • doubleLoop
  • doubleSensor
  • railCircuitStandAlone
  • singleLoop
  • singleSensor
  • tripleLoop,

  • type: type of train detector (optional; xs:string)
Possible values:
  • axleCounter: a system used in railway signalling to detect the clear or occupied status of a section of track between two points. The system generally consists of a wheel sensor (one for each end of the section) and an evaluation unit for counting the axles of the train both into and out of the section [wikipedia].
  • axleCountingCircuit: virtual track circuit
  • clearancePoint: The nominated point where rail traffic is deemed clear of others at converging points or other locations. This point may or may not be delineated by signs or clearance posts [Australian Rail Track Corporation Limited].
  • insulatedRailJoint: a small gap between two rail sections filled with an insulating material [Sandström].
  • trackCircuit: an electrical device used to prove the absence of a train on rail tracks to signallers and control relevant signals [wikipedia].
  • virtualClearancePoint: describes a clearance point, that is not linked with a physical element,
    e.g. the "police man" in Germany.,

  • id: the identifier of the object; this can be either of type xs:ID or UUID (obligatory; xs:string; patterns: (urn:uuid:)?[0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{12}|\{[0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{12}\}); compare: Dev:Identities
Elements may have different parent elements. As a consequence they may be used in different contexts.
Please, consider this as well as a user of this wiki as when developing this documentation further.
Aspects that are only relevant with respect to one of several parents should be explained exclusively in the documentation of the respective parent element.
