The main objective of the present standard is to present the reference data model for public transport, based on:
— the reference data model, EN 12896, known as Transmodel V5.1;
— EN 28701, known as IFOPT;
incorporating the requirements of:
— EN 15531-1 to -3 and CEN/TS 15531-4 and CEN/TS 15531-5, Service interface for real-time information relating to public transport operations (SIRI);
— CEN/TS 16614-1 and CEN/TS 16614-2, Network and Timetable Exchange (NeTEx), in particular, the specific needs for long distance train operation.
A particular attention is drawn to the data model structure and methodology:
— the data model is described in a modular form in order to facilitate the understanding and the use of the model;
— the data model is entirely described in UML.
