Service Interface for Real Time Information
The Standard Interface for Real-time Information or SIRI is an XML protocol to allow distributed computers to exchange real-time information about public transport services and vehicles.
The protocol is a CEN norm, developed originally as a technical standard with initial participation by France, Germany (Verband Deutscher Verkehrsunternehmen), Scandinavia, and the UK (RTIG)
SIRI is based on the CEN Transmodel abstract model for public transport information, and comprises a general purpose model, and an XML schema for public transport information.
A SIRI White Paper is available for further information on the protocol.
CEN SIRI allows pairs of server computers to exchange structured real-time information about schedules, vehicles, and connections, together with informational messages related to the operation of the services. The information can be used for many different purposes, for example:
CEN SIRI includes a number of optional capabilities. Different countries may specify a country profile of the subset of SIRI capabilities that they wish to adopt.
The CEN SIRI standard has two distinct components:
SIRI V1.0 defined eight functional services:
