The Open Service Initiative is the implementation of the „Open Government Data“ concept in the River Information Services domain. Non-personal data is made publicly available by the administration.

A majority of the fairway information offered in DoRIS is now also available via predefined web interfaces. The interfaces and their content are described on the Open Service Portal. Each service category can be tested without registration (query frequency limited) by clicking the „Try it out“ function button.

Permanent interface usage

For a permanent use of the interfaces as well as integration of these in third-party applications (e.g. application manufacturer), it is necessary to request a so-called API key.

Please send an official request to doris-info[at] with the following information:

  • Applicant name (including company contact person)
  • Company / Private person
  • Address
  • Reason of usage
  • Required interfaces

After successful examination, the responsible colleagues provide an API-key which guarantees unrestricted use of the requested interfaces.
