Hey Andrew, Since you volunteered to be the release manager for 0.3 I think its about time to get the ball rolling on making a 0.3 release of OODT. The best place to start is the https://cwiki.apache.org/confluence/display/OODT/Release+Process . The previous release managers have updated that document as they have gone along and its a great starting point. I think we should definitely get https://issues.apache.org/jira/browse/OODT-129 resolved which will require some updates to the release process. Cameron has already started part of this by submitting an infra ticket (https://issues.apache.org/jira/browse/INFRA-3591) but as the 0.3 release manager you will likely be the first to test it out.
Overall what we are trying to do with maven central is documented here http://www.apache.org/dev/publishing-maven-artifacts.html . If you have questions feel free to ask. Thanks, Paul
