This document discusses guidelines for making archaeological data findable, accessible, interoperable, and reusable (FAIR). It is funded by the European Commission and aims to support the creation and sharing of FAIR archaeological data. The document introduces the FAIR data principles, which are designed to make data more easily discoverable and usable. It also discusses the role of metadata, identifiers, standards, and repositories in making archaeological data FAIR. Guidelines are provided around each letter of FAIR to help researchers and institutions implement good research data management practices.
