I'm sorry, is there some definition of Open Source that I'm not aware of?
Another defintion is if the code is released under and OSI approved "open source licence" (http://opensource.org/licenses/alphabetical ) or an FSF approved "free software licence" ( http://www.gnu.org/licenses/license-list.html ). Again AFAIK, nearly exactly the same.
