h2. IP clearance

The former code base of OpenOffice.org used several external libraries and code with incompatible licenses (see also [Third-Party Licensing Policy|http://www.apache.org/legal/3party.html]) that cannot be longer used in the Apache Open Office project or at least not in the same way. A first overview of critical stuff can be found on the "[Migration|http://wiki.services.openoffice.org/wiki/ApacheMigration]" page in the community wiki. This page is intended to document the ongoing work of the IP clearance in more detail but still high-level.

The process will be redefined and improved over time and in the end we will end up with an automated process using the Apache Release Audit Tool (RAT) to ensure that we have always a clean code base for Apache Open Office.
