Digital Academic Archives and Repositories (DABAR) is a national repository system that provides all research and higher education institutions in Croatia with infrastructure for reliable preservation and dissemination of research and educational outputs. DABAR was launched in 2015 and since then Croatian institutions used it to establish 126 digital repositories, including 10 university repositories and 2 national repositories. There are more than 87,000 digital objects stored in the repositories in DABAR, of which more than 37.000 are available in Open Access. Currently, DABAR supports curation of papers published in journals and conference proceedings, book chapters, books, presentations, datasets (research data), theses and dissertations, and various types of artistic works (photographs, audio and audio-visual content). The support for various types of digital objects together with new functionalities is continuously being provided by SRCE - University of Zagreb University Computing Centre in association with a number of research and higher education institutions in Croatia. Repositories in DABAR are compliant with OpenAIRE guidelines and have built in support for publishing of research data according to the FAIR data principles (Findable, Accessible, Interoperable, Reusable). By providing publications and research data in Open Access in repositories, institutions can fulfil the requirements of research funders to make research outputs openly available (e.g. EC requirement for H20202 research project), make their research more visible and transparent and underpin the idea of Open Science.
