The ultimate goal of FAIR is to optimize the Reuse of data. To achieve this, metadata and data should be well-described and documented so that they can be replicated, understood and/or combined in different settings. Think of variable labels, codebooks, protocols and instruments used, attaching a license, etc. This checklist details what to include in a data package besides the data itself. The data package can be deposited in data repository such as UvA/HvA figshare.
