The amount of open-source-software (OSS) used in the global software engineering community is enormous and growing at an exponential pace. This includes both the products we develop and the development tools we use to create them. It is meanwhile rare to find examples of products that do not contain open source components. Although, using open source components in products does have many advantages, it is very important that one also manages the use of the open source components in a license compliant way. A set of companies and other organizations who either offer or use OSS-based license compliance tools have recently formed the “Open Source Tooling Group”. This international group works on establishing an ecosystem of OSS-based tools for license compliance that fit together well and can offer an end-to-end solution for organizations who want to use these tools to fulfill their license compliance obligations. This talk provides the motivation and overview of this topic describing the relevance to both software engineering practitioners. It will close by highlighting some of the research areas where further improvements could be done in this fast-growing field.
