Mendeley Data is a multidisciplinary, free-to-use open research data repository, where you can upload and share data files up to 10GB so they are archived, preserved and findable for the long-term. To ensure that research data stands the test of time, each version of a dataset is given a unique DOI, and permanently archived with DANS (Data archiving and Networking Services), ensuring that every dataset and citation will be valid in perpetuity.
