F – Findable
Data is assigned a persistent identifier (e.g. DOI) and meaningful metadata so that it can be easily found.

A – Accessible:
There are clear rules governing how and under what conditions the data can be accessed – even where access is restricted.

I – Interoperable:
Open formats and common standards make it possible to link data with other datasets and process it further.

R – Reusable
Good documentation and a clear licence make the data comprehensible and reusable by third parties.
