The aim of this paper is to initiate the discussion on current trends in sharing research data (and other materials related to the research process) in the Czech linguistic community. First, we present a brief explanation of what the primary incentives are for data sharing.
Second, we discuss nine main reasons for sharing data and other research materials. These are verifiability of the results, prophylactic effects, replicability, synergy and cooperation between the researchers, use of data in teaching, social and ethical responsibility, easy accessibility and interpretability of the results, data as an outcome, and the possibility to conduct a meta-analysis.
Third, we focus on several examples of good practice, i.e. the Czech National Corpus, the LINDAT/CLARIAH-CZ infrastructure, TROLLing, and the Open Science Framework. As a conclusion of the paper, we present three appeals for Czech linguistics: (a) Academic journals should require data sharing as a standard aspect of the publication process, (b) academic institutions should require sharing of data and other research materials by the academic staff, (c) universities should adopt clear rules for sharing of data and other research materials for students.
