A large project like Souver@n requires some basic requirements, which in this case are covered by the project Basis-Souver@n be created. The ELAN e. V. is involved in dismantling the different versions of the software systems of the network partners by, among other things, bringing interfaces between the Opencast lecture recording system and the learning management systems or the BigBlueButton video conference system to a uniform level. Here ELAN e.V. benefits from its great expertise in the development of open source software and the team of highly qualified developers with many years of experience, which are available in sufficient numbers on an ad hoc basis.
