Former PRIFIS

Project information

  • Acronym: OSDM platform (former PRIFIS)
  • Open Sales and Distribution Model platform (former Price and Fare Information Storage)
  • Project director: Marc Guigon
  • Project manager: David Sarfatti
  • Status: ongoing project
  • Project code: 2010/PAS/552

Project description

Implemented in 2004, PRIFIS (PRIce and Fare Information Storage) is a database containing price and tariff data for more than 30 railways. The price and fare data exchanged are described in UIC Leaflet 108-1 (NRT).

PRIFIS was fully redesigned a number of years ago due to difficulties with the old format and obsolete technology. In 2020, UIC completed the procurement process for implementation of a tool to replace PRIFIS and the design of a new, related specification called Open Sales and Distribution Model. The new system is called OSDM Platform and is a central database for twice-yearly exchange of prices and tariffs for non-yielded tickets.

To facilitate change management, UIC also provides a converter to transform the railways’ old 108-1 format into the new OSDM format.

36 railways are expected to use OSDM in production by August 2021: VR, BC, UZ, CFM, LG, LDz, EVR, KZH, GySEV, ŽRS, CIE, TCDD, CFL, FS, SNCF, CP, ZPC, GC, FARYM, TrainOSE, NSB, DB, SNCB, FPC, BDZ, CFR, ČD, MÁV, ZSSK, SV, SJ, HŽ, SŽ, ÖBB, NS, SBB, DSB and PKP.

IRS 90918-10

The new OSDM standard comprises two parts: online distribution (transport and reservation) and offline distribution (transport only). Whereas previously the two distribution standards were separate, OSDM enables the sale of both online and offline tickets in a single interface.

For online distribution, the new OSDM standard uses an API (application programming interface) which enables distribution of international travel tariffs and prices and seat reservations among railway companies’ distribution systems in real time and makes train tickets available to third party vendors around the world.

By collaborating more closely with distributors (FSM initiative) using a single interface between the various stakeholders (distributors, allocators, carriers, etc.), the railway sector as a whole has taken a major step forward in simplifying ticket distribution for passengers, including through-ticketing, and in developing a consumer-driven, innovative and competitive distribution solution based on transparency and sustainability.

The standard is defined in IRS 90918-10 and provides a new open sales and distribution interface for the passenger transport sector as follows:

  • Can be used for all fares, including domestic (offline and online)
  • Interface for (multimodal) trip search (online) including bus or local transport ticketing
  • Interface for booking/reservations (online)
  • After sales for booking/ticket reservations and ancillary services (offline and online)
  • Graphical seat reservation (online)

The technical OSDM JSON format used online is also used offline to exchange tariff data for NRT (non-reservation ticket) trains between railways twice per year.

To enable widespread take-up by railways, UIC has decided to publish the OSDM specification, IRS 90918-10, in Apache 2.0 open licence.

OSDM Platform

As an important first step, the OSDM working group validated the offline OSDM specification in October 2020, and it can now be used by railways’ distribution systems. UIC awarded implementation of the new offline OSDM Platform to replace PRIFIS to Hit Rail.

Development of the OSDM Platform began in October 2020, and it becomes operational in July 2021.

The OSDM Platform is provided as a Software as a Service (SaaS) cloud-based solution. Its architecture enables ongoing introduction of future UIC services relating to the distribution of tariff and price data. The technical components of the solution are deployed in a fully virtual, enterprise-grade cloud environment.

Railway customers will be able to purchase rail and multimodal transport tickets across Europe more easily at the most beneficial prices and tariff conditions. Thanks to OSDM’s ability to provide a combination of fares, customers will be able to combine fares on the basis of existing fare combinations as well as new fares and/or combination models.

Railway operators will be able to provide better services and attract new customers thanks to a combination of technical innovation and smart mobility solutions for seamless travel. By streamlining the distribution process, the railway sector benefits from reduced development and distribution costs.
