There is an array of Open Source licences out there, each with subtle, but often important, differences. Understanding the appropriate licence for your project and knowing your responsibilities with respect to components you reuse is critical to the success of any project developing or reusing Open Source products. Furthermore in order for users to adopt and reuse your code you must be able to demonstrate that you have the necessary rights to distribute under the chosen license. This presentation will cover each of these aspects of IP management in an open source project.
