ClearlyDefined is a free service and open source project from the Open Source Initiative (OSI) that helps organizations ensure supply chain compliance and security. Generating SBOMs at scale for each stage on the supply chain, for every build or release, has proven to be a real challenge. And fixing the same missing or wrongly identified licensing metadata over and over again has been a redundant pain for everyone. This is where ClearlyDefined shines, as it makes it really easy for organizations to fetch a cached copy of licensing metadata for each component through a simple API and fix any issues, which is always up-to-date thanks to its crowdsourced database. In this session, we’ll provide an introduction to ClearlyDefined and discuss the latest developments. We’ll provide case studies of how organizations like GitHub, SAP, Microsoft, and Bloomberg are leveraging ClearlyDefined not only for their own needs internally, but for the benefit of all.
