How does the Sun Contributor Agreement differ from prior ones?
The new Sun Microsystems Inc. Contributor Agreement (SCA) for OpenOffice.org contains an addendum that excludes non-core contributions, like extensions and documentation, from the joint copyright assignment, provided that these components are not intended to be included in the OpenOffice.org product that can be downloaded from OpenOffice.org. The new agreement also protects against patent misuse and abuse and thus works with the LGPL v3 to ensure a more stable open source community. The SCA further provides for stronger patent protection and includes an exception for extensions and documentation not present in prior agreements.
