Changes in prioritization may cause the development roadmap to change – NIIS may introduce new features and/or postpone implementation of current features. The X-Road product backlog is prioritized by the X-Road Steering Committee.

2024–2031

The X-Road core development roadmap for 2024–2031 is presented in figure 1.

X-Road 8 “Spaceship” 🚀

X-Road 8 nurtures the proven ecosystem model and security while it takes X-Road to the next level by providing a solid data space infrastructure. The very first step is to implement a proof of concept that is divided into two phases taking place in 2024.

The first phase takes place in H1/2024 and its aim is to validate the feasibility of replacing X-Road's custom protocol stack with the data space protocol stack. The project also tries to ensure smooth integration with previous X-Road versions for backwards compatibility, estimate the changes required for information systems when transitioning to X-Road 8, and assess potential changes to existing X-Road components.

The proof of concept results are expected for review in May 2024. The second half of the year will witness another project to test the results within Estonia’s X-Road ecosystem.

X-Road 7 “Unicorn” 🦄

X-Road 7 is implemented iteratively using agile software development methods. All the changes are not included in the first production version, but they will be introduced one by one over time in various X-Road 7 minor versions.

X-Road 7 is backward compatible with X-Road 6. The version upgrade from version 6 to version 7 is almost like upgrading from one X-Road 6 minor version to another.

The development of X-Road 7 is divided into multiple high-level focus areas. Each focus area consists of several topics that will be turned into actual features. The high-level focus areas and their main topics are listed below.

Messaging patterns

In addition to the currently supported synchronous request-response messaging pattern, X-Road 7 will support the publish-subscribe messaging pattern. The pattern supports one-to-many communication that is one of the key enablers of proactive life-event based services. Also, support for data streaming and better support for transferring large files will be investigated further. Existing solutions that could be utilized in the implementation will be evaluated, for example, Apache Kafka.

Message logs

Providing indisputable evidence of data exchange is one of the X-Road’s core functions. However, there are use cases that require only metadata logging or do not require logging at all. X-Road 7 will make message logging more configurable and introduce new security measures for protecting the logs.

Onboarding process

Onboarding of new X-Road members, Security Servers and subsystems will be made faster by streamlining and automating different steps required in the process. For example, adding more automation to the certificate application and renewal processes is studied further.

Architecture

X-Road 7 will be more modular and enable installing only the components that are needed. Developing new add-ons will also be easier. X-Road 7 will support containers and it can be run on container management platforms and in the cloud.

Operational insights

X-Road 7 will provide access to the operational monitoring data collected by the Security Server. The Security Server’s user interface will provide a dashboard for viewing and exploring operational monitoring data locally.

Sustainability

X-Road 7 will optimise the use of resources and decrease the environmental footprint of X-Road.
