“The http://re3data.org registry allows the easy identification of appropriate research data repositories, both for data producers and users. The registry covers research data repositories from all academic disciplines. Information icons display the principal attributes of a repository, allowing users to identify the functionalities and qualities of a data repository. These attributes can be used for multi-faceted searches, for instance to find a repository for geoscience data using a Creative Commons licence.
By April 2013, 338 research data repositories were indexed in http://re3data.org. 171 of these are described by a comprehensive vocabulary, which was developed by involving the data repository community (http://doi.org/kv3).
The http://re3data.org search at can be found at: http://www.re3data.org
The information icons are explained at: http://www.re3data.org/faq” (IP-OA-Forum)
