Enhancing FAIRness and TRUSTworthiness in the REPOPSI open repository

As the first centralised repository for psychological instruments in Serbian, one of the main goals of the project was to prevent duplication of efforts in translating/adapting instruments and to provide a space for local researchers to promote their original instruments. A further challenge was to facilitate easy access to essential materials for researchers and students. While the Open Science Framework - the free platform hosting REPOPSI - is a valuable hosting platform, this also posed challenges in terms of Reusability (e.g. metadata cannot refer to a machine-understandable reuse licence) and Interoperability (e.g. metadata values cannot be expressed using a controlled vocabulary). REPOSI also had the need to promote its data and services to a wider, global research community.
