BS EN 15320:2007

BS EN 15320:2007 describes the basis of an environment which aims to:

• provide a basis for offering machine readable interoperable tickets across the public transport network in Europe
• satisfy the demand for securing a seamless journey for the passenger allowing them travel with all participating operators, possibly in different networks and countries, using a single card while in the context of not inhibiting commercial competition

BS EN 15320 describes those components of the application necessary to support an interoperable environment including:

• accessing the Interoperable Public Transport Application
• data structure and presentation
• sizing and enumeration of data
• data access methodology
• security and access considerations
• dealing with legacy systems.

As a foundation for interoperability, BS EN 15320:2007 provides the basis for interoperability across instances of the application supplied by different parties subject to commercial agreement and exchange of details of the physical interpretations of the Standard.
