A publisher must implement a SSO service interface for its own system, which is used to check the authenticity of messages coming from the Dikaios. Each publisher has their own private key, which is used in the authentication process. A publisher must verify both the authenticity and the timestamp of a message. If timestamps are used, server's time must be synchronized via NTP. As for the validity of timestamps, as a general rule, time period of +- 30 seconds from creation of a view link is considered to be valid.
All learning materials from a publisher must be available in the Dikaios. In Finland, at least the following information is required:
As a general rule for steps in user redirection, when moving from e-learning environment to the publisher's own service
1. E-learning environment
2. Dikaios (user rights management and usage statistics)
3. Publisher's SSO (log in) and directing to the selected learning material.

Content will be served directly via Dikaios. In this case integration into the publisher's systems isn't required.
Publisher can add learning material via an user interface. It is also possible to use push type of adding.
Publisher returns learning outcomes automatically
Publisher must implement both course and student feedback systems. Feedback queries must use dikaios_resource_uid or lms_course_id.
User can move, via a link, from Dikaios learning outcomes viewer to a publisher's own system.
