Best practice in modern research data management argues for the deposition of validated experimental data sets in publicly accessible repositories. Such depositions should meet the FAIR principles (that scientific data should be findable, accessible, interoperable and reusable), on which funding bodies increasingly insist. In so doing, they will include sufficient metadata to allow verification and reproducibility of published research results, and provide the scientific community with a curated collection of valuable data. The benefits of such a collection include independent validation, reanalysis and the ability to extract new science from existing data as new techniques appear.
