    • Copyright in Canada
    • Copyright Guide
    • In a software project, there can be many copyright holders (e.g., many contributors), or all contributors may assign their copyright to the project (e.g., CLA, which we'll cover later)
  • Licenses
    • Rights, privileges, responsibilities, etc. applicable to someone other than the work's creator
