1. Deposit research data needed to validate the results presented in scientific publications, including associated metadata, in the repository as soon as possible. Also other data (for instance data not directly attributable to a publication, or raw data), including associated metadata, should be deposited. 2. Take measures to enable any third party to access, mine, exploit, reproduce and disseminate (free of charge for any user) this research data, for instance by attaching a Creative Commons Attribution Licence (CC BY) to the data deposited, or by waiving all interests associated to copyright and database protection using the CC0 tool. 3. Provide information via the chosen repository about the tools available in order for the researchers to validate the results, e.g. specialised software or software code, algorithms and analysis protocols. Where possible, these tools or instruments should be provided.
