open source and copyright

  1. 1. OPEN SOURCE AND COPYRIGHT<br />Open source is a development method for software that harnesses the power of distributed peer review and transparency of process. <br />All the open source models depend, in a large proportion, on the validity of open source licenses, in case they are at some point challenged in courts.<br />
  2. 2. Software is considered “open source” if its distribution terms are open and free. <br />Free software is a matter of the users&apos; freedom to run, copy, distribute, study, change and improve the software. <br />
  3. 3. Program&apos;s users should have the four essential freedoms: <br />1. The freedom to run the program, for any purpose<br />2. The freedom to study how the program works, and change it to make it do what you wish. Access to the source code is a precondition for this. <br />3. The freedom to redistribute copies so you can help your neighbor. <br />4. The freedom to improve the program, and release your improvements (and modified versions in general) to the public, so that the whole community benefits.<br />
  4. 4. Copyright law, by default, do not allow for redistribution (nor even use) of software. <br />MOVIE<br />
  5. 5. PUBLIC DOMAIN<br />The simplest way to make a program free software is to put it in the public domain, un copyrighted. <br />This allows people to share the program and their improvements, if they are so minded. <br />But it also allows uncooperative people to convert the program into proprietary software. <br />They can make changes, many or few, and distribute the result as a proprietary product. People who receive the program in that modified form do not have the freedom that the original author gave them.<br />
  7. 7. GNU / COPYLEFT<br />Copyleft = license requiring all modified and extended versions of the program to be free as well. <br />When redistributing the program, you cannot add restrictions to deny other people the central freedoms. <br />To copyleft a program, you first state that it is copyrighted; then add distribution terms, which are a legal instrument that gives everyone the rights to use, modify, and redistribute the program&apos;s code, or any program derived from it, but only if the distribution terms are unchanged. <br />The code and the freedoms become legally inseparable.<br />
  8. 8. FREE SOFTWARE FOUNDATION<br />The Free Software Foundation (FSF) is a nonprofit with a worldwide mission to promote computer user freedom and to defend the rights of all free software users.<br />Promoting the development and use of free software and documentation and by campaigning against threats to computer user freedom like Digital Restrictions Management (DRM).<br />(you can find list of all licenses on their web site) <br />
  9. 9. CREATIVE COMMONS LICENSES<br />Creative Commons defines the spectrum of possibilities <br />between full copyright and the public domain. <br />ALL RIGHTS RESERVED / SOME RIGHTS RESERVED / NONE RIGHTS RESERVED<br />This licenses are not an alternative to copyright. They work alongside copyright, so you can modify your copyright terms to best suit your needs. <br />THE COMMONS<br />They created online database — the body of work that is available to the public for free and legal sharing, use, repurposing, and remixing. <br />
  10. 10. OPEN SOURCE INITIATIVE<br />The community-recognized body for reviewing and approving licenses as OSD-conformant.<br />The OSI is actively involved in Open Source community-building, education, and public advocacy to promote awareness and the importance of non-proprietary software.<br />
  11. 11. OPEN RIGHTS GROUP<br />Open Rights Group is the UK’s leading voice defending freedom of expression, privacy, innovation, consumer rights and creativity on the internet. <br />We campaign to change public policy whenever citizens&apos; or consumers&apos; rights are threatened. We do this by talking to policy-makers and mobilising our supporters to stop bad laws in the UK and EU<br />
  12. 12. License that are popular and widely used <br />GNU General Public License<br />GNU Library General Public License<br />Apache License, 2.0<br />New and Simplified BSD licenses<br />MIT license<br />Mozilla Public License<br />Common Development and Distribution License<br />Eclipse Public License<br />
  13. 13. Shareware is software which comes with permission for people to redistribute copies, but says that anyone who continues to use a copy is required to pay a license fee. <br />Proprietary software is software that is not free or semi-free. Its use, redistribution or modification is prohibited, or requires you to ask for permission, or is restricted so much that you effectively can&apos;t do it freely. <br />Freeware are packages which permit redistribution but not modification (and their source code is not available). These packages are not free software!<br />Semi-free software is software that is not free, but comes with permission for individuals to use, copy, distribute, and modify (including distribution of modified versions) for non-profit purposes.<br />
