History of OSDM
The Open Sales and Distribution Model has emerged from the new Tariff Model (nTM) and Full Service Model (FSM 2.0) initiatives:
The initiative new Tariff Model (nTM) initiated by UIC established the successor standard of PRIFIS. It defines on the one hand an offline standard for the exchange of priced segments (formerly: PRIFIS series) and on the other hand a new online standard for the purchase of dynamically priced segments. The priced segments are calculated and provided by so-called fare providers. The priced segments are fetched by an distributor which combines these priced segments into a consistent offer and later into a booking and ticket. Essentially, this process allows the vision of “one trip - one ticket within Europe” to materialize.
The Full Service Model (FSM 2.0) initiative defines an open standard for the distribution of rail services (bookings, reservations, integrated reservations and additional services) within Europe and beyond. By standardizing the distribution interface, the distribution of products and services can be greatly simplified.
To join forces and represent the public transport sector as a whole the two initiatives have been merged into this initiative.
