Data Exchange Layer X-tee
X-tee, the data exchange layer for information systems, is a technological and organizational environment enabling a secure Internet-based data exchange between information systems.
To exchange data, a member of X-tee describes the shared data and other members can use that data based on an agreement. Due to the large number of systems that have joined X-tee, all members of X-tee can use the services and data of other members to improve their own business processes.
X-tee has a versatile security solution: authentication, multi-level authorisation, high-level system for processing logs, and data traffic that is encrypted and signed.
X-tee and X-Road are registered trademarks:
X-tee is a data exchange layer used in Estonia. Until 2018, it was named X-Road in English. Since 2018, however, X-Road is only used to refer to the technology developed together by Estonia, Finland and Iceland through MTÜ Nordic Institute for Interoperability Solutions. The Estonian X-tee is now also called X-tee in English.

How does X-tee work?
X-tee is based on an interoperable ecosystem and a technical ability to exchange data. To exchange data, one member of X-tee describes the shared data and other members are able to use this data based on an agreement.
Due to the large number of systems that have joined X-tee, all members of X-tee can use the services and data of other members to improve their own business processes.
One example is a solution by the police for controlling driving licenses. A driver no longer has to carry a physical driver’s licence with them, as a police officer can, via X-tee, make an operative inquiry from the database of the Republic of Estonia Road Administration using an identification document to control driving licenses. The Tax and Customs Board has a somewhat similar data service that enables controlling tax arrears of private or legal persons.
To implement already created services, you must become a member of X-tee, install an X-Road security server, make an agreement with a suitable X-tee service provider, work out a logic to create the internal data for the service you chose, and process the reply. X-Road& has been developed for over ten years now, and a large amount of code is available, which significantly simplifies the creation of new solutions. In the X-Road context, the reusable code is called a reusable component ».
If there is no suitable X-tee service yet, it can be created in cooperation between the parties. Very specific and sensitive data can also be exchanged. We follow the principle that the owner controls the data throughout the whole process, and the X-Road technology only offers a secure data exchange.
X-tee enables exchanging many types of information: simpler cases involve texts, but you can also exchange files.
Operating principles of X-tee
Independence of platform and architecture – X-tee enables the information systems of X-tee members on any software platform to communicate with the information systems of data service providers on any software platform.
Multilateralism – X-tee members are able to request access to any data services provided through X-tee.
Availability and standardisation – for managing and developing X-Road, international standards and protocols are used where possible.
Security – exchanging data through X-tee does not affect the integrity, availability or confidentiality of the data.
Global X-Road Community
The global X-Road Community is hosted by the Nordic Institute for Interoperability Solutions.
The community uses, among other things, a Slack channel, which welcomes all developers, administrators, and other interested parties.
