  • Not an instance

    A 'restricted access' repository deposit.

  • Not an instance

    Aggregate tables in a paper appendix without the row-level data.

Editorial commentary

Open data in research is bounded by ethical, legal, and consent constraints. Where fully open release is impossible, alternatives include controlled-access deposits, synthetic data, and aggregate releases. The Open Definition (Open Knowledge Foundation) is the canonical definition of 'open'; alignment with FAIR is complementary rather than equivalent.
