At SFScon 2021 in Bolzano (Italy), I presented REUSE as a gold standard approach for Free and Open Source Software licensing. The REUSE initiative, launched by the Free Software Foundation Europe, provides best practices and tools that make licensing Free Software projects straightforward and unambiguous. By following three simple steps – providing license and copyright information in every file, including license texts, and confirming REUSE compliance with the tool – projects can achieve clarity that benefits both developers and users.
The talk demonstrated how REUSE addresses common licensing challenges in Free Software development: unclear provenance, missing copyright information, and ambiguous licensing terms. I showed practical examples of how projects can adopt REUSE incrementally, explained the supporting tools available (including the REUSE helper tool and API), and discussed how REUSE is being adopted by major projects and organizations. The approach helps projects be compliant with requirements like the FSFE's "Public Money, Public Code" campaign and prepares them for emerging regulations.
REUSE has become increasingly recognized as a best practice standard, with adoption by major organizations and integration into compliance toolchains. The talk highlighted how this simple yet effective approach removes friction from Open Source licensing.
