  The modern astrophysics is moving towards the enlarging of experiments and
combining the channels for detecting the highest energy processes in the
Universe. To obtain reliable data, the experiments should operate within
several decades, which means that the data will be obtained and analyzed by
several generations of physicists. Thus, for the stability of the experiments,
it is necessary to properly maintain not only the data life cycle, but also the
human aspects, for example, attracting, learning and continuity. To this end,
an educational and outreach resource has been deployed in the framework of
German-Russian Astroparticle Data Life Cycle Initiative (GRADLCI).
