Licensing,Ppt

  1. 1. Open source licensing <ul><li>The licence is what determines whether software is open source </li></ul><ul><li>The licence must be approved by the Open Source Initiative (www.opensource.org) </li></ul><ul><li>All approved licences meet their Open Source Definition (www.opensource.org/docs/definition.php) </li></ul><ul><li>Approved licences >50 and include the GPL, LGPL, MPL and BSD. </li></ul>
  2. 2. Intellectual Property Rights <ul><li>Writing software = creating property </li></ul><ul><li>Property is always owned by somebody </li></ul><ul><li>Agreements and contracts should specify who owns property that is created </li></ul><ul><li>This may require a technical legal examination of any agreement and contracts </li></ul><ul><li>All projects which produce software need to keep complete, detailed records of the licensing and ownership of contributions to that software - an IPR registry </li></ul>
  3. 3. Copyright <ul><li>Software is protected by copyright law </li></ul><ul><li>By default only the owner of software may copy, adapt or distribute it. </li></ul><ul><li>The owner of software can agree to let another person copy, adapt or distribute the code - this agreement is called a licence. </li></ul>
  4. 4. Licence effects <ul><li>Open source licences grant the rights to copy, adapt or distribute the code to people other than the owner </li></ul><ul><li>Open source licences aim to create a community of contributors who will fix and develop the software. </li></ul><ul><li>Combining two pieces of software code under different licences can be complex. </li></ul>
  5. 5. A common myth <ul><li>There is no compulsion to release changes that you make, either under the GPL or any other open source licence </li></ul><ul><li>You may keep internal versions of GPL software that you have modified without necessarily licensing them to anyone else </li></ul><ul><li>This applies equally to individuals and legal entities like companies and institutions </li></ul>
