While the Findable, Accessible, Interoperable, Reusable (FAIR) principles have been around for a decade, it is only lately that tools and workflows for implementing them have trickled down to research communities beyond dedicated projects. This lesson is intended as a guide through FAIR Implementation Profiles (FIPs) as a means for research communities to declare FAIR implementation choices (e.g. metadata standard). The lesson was taught as a 2-hour online workshop during the Leiden University Libraries' Centre for Digital Scholarship Summer Training Week, 2025 edition.
