Sharing research data is not only allowing the reproducibility of research results and the re-use of existing data for new research questions but also makes involved researchers more visible, increases the opportunities for collaboration and boost innovation capacity of the entire society. This presentation will give an overview of three initiatives that will hopefully facilitate and promote research data sharing in Croatia: DABAR infrastructure, RDA initiative and NI4OS-Europe project. The Digital Academic Archives and Repositories (DABAR) is a national repository infrastructure that provides research and higher education entities in Croatia with the common infrastructure necessary to establish and maintain secure, reliable and interoperable institutional and disciplinary repositories. Each repository in DABAR has built-in support for storing and sharing institution’s scientific and educational digital outputs including research data. The Research Data Alliance (RDA) is a global initiative that develops social and technical conditions for data sharing, data re-using and data-driven innovation. The RDA was jointly founded in 2013 by the European Commission, the USA National Science Foundation, the USA National Institute for Standards and Technology and the Australian Ministry of Innovation. The European branch of the RDA (RDA Europe) seeks to play central role in the EU’s open science strategy, relying on a network of national RDA nodes. SRCE became a Croatian national RDA node in September 2019. The National Initiatives for Open Science in Europe (NI4OS-Europe) is an H2020 project that started on 1st September 2019 with the objective to support the coordination, convergence and federation of national and / or thematic open science initiatives by developing common tools and mechanisms of the relevance to European Open Science Cloud (EOSC). It is part of an effort to establish the EOSC, in which SRCE participates as one of 22 consortium partners.
