X-Road

X-Road is a centrally managed distributed Data Exchange Layer (DXL) between information systems. Organizations can exchange information over the Internet using X-Road to ensure confidentiality, integrity and interoperability between data exchange parties.

The first X-Road iteration was developed and launched by Estonia's Information System Authority (RIA) in 2001. The source code of its central components were released on October 3, 2016 under an MIT License. By February 7, 2018, Finland's and Estonia's data exchange layers were connected to one another. In 2017 Finland and Estonia established the Nordic Institute for Interoperability Solutions (NIIS) to continue the development of the X-Road core.
