Teaching staff can store and release their OER in one of the connected institutional archive systems according to the owner principle. The OERhub makes these locally stored OER available for broad use beyond their own institution. The centralised OERhub for OER from the higher education sector thus contributes to the national and international visibility of teaching at Austrian universities. Conceptually, a decentralised approach is pursued; the universities continue to bear responsibility for their local infrastructures (production processes, archiving). The OERhub follows the FAIR Data principles and can be easily expanded to include other universities thanks to its modular architecture and open interfaces. With its connection to Austrian universities, the OERhub is also GDPR-compliant in its handling of data.
