Other researchers can only understand, reproduce or challenge the arguments in your paper if the research data sets are publicly available. The University of Mannheim has established the MADATA research data repository to help you share your data with the research community.
Using MADATA, you can make your data sets openly accessible online. You decide on the terms under which the information is made available. This means that you can choose to use a Creative Commons license, for example, or restrict access to university members only. MADATA also assigns DOIs (Digital Object Identifiers) to your data sets, which makes it easier for the relevant users to find and cite them.
