If you have ever shared your data or software in a repository like the Johns Hopkins Research Data Repository, or on a platform like Github, you may have been asked to choose a license for your material. This workshop covers the fundamentals of open licensing for data and software, providing practical guidance for researchers who want to make their work openly available. Participants will gain an understanding of the open licenses available for data and software, factors to consider when selecting license(s), and special considerations for AI model components.
