Service Interface for Real Time Information

The Service 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 technical specification, developed with initial participation by France, Germany (Verband Deutscher Verkehrsunternehmen), Scandinavia, and the UK (RTIG)

SIRI is based on the 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 .

Scope

SIRI allows pairs of server computers to exchange structured real-time information about schedules, vehicles, and connections, together with general informational messages related to the operation of the services. The information can be used for many different purposes, for example:

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.

Current version

Version 2.0 of SIRI , representing the CEN documents as published, is currently available as an XSD file .

SIRI is kept under an informal maintenance regime, with version control. Later versions of the schema are available at the same site, together with change notes.
