O3DCon

Open source software is not "open" unless it has a license that says you can use, modify, or redistribute it. This presentation will give a comprehensive overview of what an open source license is, the different types of licenses in common use, and why they are important. In addition, you will gain an understanding of how to develop software with multiple licenses (including open source and proprietary code) and identify conflicts between licenses. We will also talk about considerations for choosing a license appropriate for your project's use case. Most important, we will answer the question: "What is all this license stuff about anyway, and why should I care?" This session is suitable for anyone who is new to open source, curious about software licensing, and includes those who already have some knowledge but want a deeper level of understanding of how licenses interact. The presenter has over 10 years of experience in software auditing, open source license scanning, and training developers in OSS license compliance.
