FAIR and Stages of Reusability
The four components of FAIR can be mapped to successive stages of reusability: possible, plausible, probable, and perishable.
The foundational principles of FAIR are Findability, Accessibility, Interoperability, and Reusability.1 Ultimately, FAIR is all about reuse, and it’s helpful for me to think of the principles as successive stages of increasing the chance that successful reuse can happen.
Findability is making reuse possible. If no one can discover your data via some open catalog, if even basic metadata is hidden in a silo, then reuse is simply not possible.
Accessibility is making reuse plausible. People and their designated software agents can not only identify relevant resources via metadata, but they can actually retrieve full data for inspection and evaluation. Now, it is plausible that your data may be reused.
Interoperability is making reuse probable. Not only is your data findable and accessible, but there is not too heavy a burden on someone to make your data compatible with their own data and processing tools. Your data is accessible in an open, standard format. You include a schema with the data, preferably in a machine-actionable format as well. Because an interested data consumer needn’t do a prohibitive amount of data cleaning/munging, it is significantly more likely that your data may be reused.
Reusability, finally, is making reuse…perishable. Using a food analogy, let’s say you have identified a potential ingredient for a recipe (findability); you know it is in stock at a nearby store (accessibility); and you have determined that it is indeed suitable for use with your kitchen tools, other ingredients you have on-hand for the recipe, etc. (interoperability). Finally, you can bring it home to your kitchen, but you won’t necessarily be able to actually use it!
FAIR is all about reuse. I hope this conceptualization of FAIR via “four Ps” helps you understand ways you can progressively enhance your data dissemination tactics and thereby enhance your data’s discoverability and reuse.
