Since NeTEx was influenced by existing European national standards and reference exchange protocols it also ensures compatibility with VDV452 (“VDV Standard Interface Network / Timetable” reference exchange protocol in Germany) at the level of conceptual and physical model. The aim of the VDV452 is to transfer network definitions and timetables from a source system into a target system, i.e. the timetable data from a scheduling program is transferred to consumer systems for the purpose of transit operations. NeTEx’s physical model provides specific elements (i.e. ExternalStopPointRef, ExternalJourneyRef, ExternalInterchangeRef, etc.) for VDV compatibility, specifically for use in AVMS systems.
