The current Abitti 1 version runs on Debian Linux. The end-of-life of the underlying DigabiOS distribution will happen after the test days in spring 2026.
In Digabi 1, test takers start their laptops from USB sticks and the servers run in a similar fashion. You can run the server as VirtualBox VM. For this, we have an end-user helper application, Naksu.
While Debian GNU/Linux is itself based on open source, the Abitti exam system is not. Also, the disk image contains 3rd party software with separate licenses. All end-user licenses and the record of processing activities can be found at Abitti.fi.
If you are providing applications to Abitti 1 you might want to take a look at the instructions how to tinker Digabi 1 (DigabiOS).
DigabiOSWe are working with the next generation Abitti 2 to be used in Matriculation Examination tests from autumn 2026 onwards. It is based on an installable kiosk-mode browser application, and HTML5 based third-party applications storing files to a test-time cloud storage.
The Digabi 2 codebase is yet to be published as open source.
The third-party applications, such as calculators or office suite, runs in their own Docker containers. For information concerning the application environment see the most the most up-to-date documentation we have.
Digabi Abicode is the codebase for the Python programming environment used in Abitti 1 and Abitti 2 exam systems.
Abicus is a simple scientific calculator built on web technologies. Abicus does not include any symbolic computation capabilities.
Digabi Exam Admin is the codebase for the service to administer tests i.e. create new tests, distribute tests, grade tests and send graded test answer to candidates who participated in the tests. This source code is used in the service found at oma.abitti.fi but doesn't include the necessary credentials to administer tests in that service.
The Digabi Exam Engine is an XML-based specification that’s used in rendering the tests including test items and accompanying materials in a user friendly and accessible way for candidates taking tests. By following the specification one can create new tests that are technically coherent with the actual Matriculation Examination tests and can be graded with the tools offered in Digabi Exam Admin.
The Answer Field is the “answer box” used in Digabi Exam Engine that enables using mathematical notation and copy-and-paste math formulas and images from the clip board. The same solution can be used in e.g., digital learning material, online exam environments etc.
