Understand more with Data Definitions

Data Definitions has replaced Definition of Specifications. It’ll continue to provide all the same descriptions and information as before, but with a new, easier-to-use look and feel.

We’re delighted to update this key resource for customers. Data Definitions enables you to translate OEM terminology from across the market, and understand the items, attributes and values we research and code.

To access the platform, simply follow the link below and log in using your JATO Support Centre username and password.


Please note that you will no longer be able to access the definitions platform directly from V5. You may wish to bookmark the new site or follow the links from jato.com.
