5th-6th April: Open Source Software Licensing Workshop for Software Developers

Building Sustainable Software Projects by Using Good Licensing Practices

Open-Source Software (OSS) is broadly used in almost all software development projects in the GÉANT project, and so good practice of using appropriate licenses is crucial to protect GÉANT applications and organisation.

What you will learn

This course provides a practical dive into the open-source licensing and compliance practices. The course is led by OSS experts: Andrew Katz and Alex Murphy from Orcro Limited. By applying what you explore in this class, you will be able to:

  • Apply general open-source licensing concepts subject to a permissive, copyleft or non-open-source licence
  • Combine components under different licences into a single application.
  • Select components for your project, based on the licence applicable and other criteria.
  • Determine whether components under different licences are compatible based on a license matrix
  • Detecting incompatibilities and other issues using WhiteSource (now Mend) compliance tooling
  • Apply criteria involved in selecting an out-licence for a project using both a manual selection process (using a component spreadsheet) and compliance tooling (WhiteSource – now Mend).

Course Overview

Who should attend
This course has been designed for software developers and engineers who are contributing to open-source projects and/or developing internal projects. It is also recommended to leaders responsible for the development tasks in the GÉANT project
