Key Features

• Users can discover the kinds of data held in different systems.
• By publishing data definitions, system developers make them visible in a standardised format, and this encourages others to look to reuse existing definitions and existing data, where possible.
• Through model submission and status reviews, the quality of the data documentation is improved and the chance of data reuse is increased.
• The registry process encourages harmonisation of data definitions. This allows users to understand how different data sets relate to each other, and makes system integration more productive.
• The registry answers questions for ITS developers, increasing efficiency of ITS development

Who is the registry for?

The registry can be useful for many ITS stakeholders, including system developers, system integrators, system procurers and standards developers.

During system specification the registry can be searched for re-usable definitions in specific functional areas. The registry can also be used as an online specification for data interchanges. For example, those wishing to write a TIH travel information receiver application can (if the TIH data source has been registered) use the registry to get the detailed specification of the data formats and semantics.

The registry is currently being used by the Highways Agency to improve the quality of standards under development, such as the European DATEX II specification for the publication of travel information. The registry produces a wider spectrum of review feedback and causes the consideration of requirements and representations from across the range of registered models, encouraging harmonisation.
