Research data is an important and valuable resource. However if data is not correctly preserved, it can be lost; and if not correctly managed, it can be missed, manipulated, or altered.
It is crucial to perform a proper and responsible research data management according to the FAIR principles, which are guidelines set out in 2016 aimed at improving the Findability, Accessibility, Interoperability and Reusability of research data and outputs. They which play an important role in making your data available for reuse to other scholars (but also to you future-self). Importantly, planning in advance is key for managing your research data according to the FAIR principles and guaranteeing the reproducibility of your research.
Indeed, thinking about data before starting to produce it will help you manage it better:
- Think about data responsibilities and rights, as well as possible ethical and legal issues: check the checklist!
- Select the repository in which you will share your research data and check its policies and requirements: to help you choose, use this guide or discover more about UNIMI's Dataverse
- Start writing a Data Management Plan to deal with all this issues!
Navigate in the sections below to learn more about each letter of the FAIR acronym:
Findable
Your data can be found by others if you have:
- associated it a globally unique persistent identifier (PIDs, such as a DOI)
- used rich and detailed metadata to describe your data
- deposited it in repositories, catalogs and databases which enable automatic harvesting of metadata (indeed, if you choose the right one half of the work is done!)
- sponsored it
Interoperable
Other researchers should be able to use your data with their own data if your data is clearly comprehensible. It can be achieved if you:
- describe your data in a detailed and comprehensible way in the metadata fields
- add helpful and detailed documentation on data creation and processing: compile a readme file
- use the right language: well-known terminology, domain standards, English language
- use readable, non-proprietary and open formats
Accessible
Data and metadata should be preserved in the long term such that they can be easily accessed and downloaded. It can be achieved if you:
- have shared your data in a dedicated repository
- openly published your metadata with a public domain license
- used clear statements and instructions for closed data: remember that access to your data should be easy, but it does not mean that everything must be shared without limitations. The moto is: as open as possible, as closed as necessary.
Reusable
Other researchers should be allowed to (confidentially) reuse your data if:
- data and its provenance is trustworthy: describe it (and all the processes on data) in detail in the metadata and in the readme file
- open licenses have been used for both metadata and data to make clear what it is allowed to do with the data
