KnowledgeTree, the provider of Open Source document management software for small to medium-sized organizations and departmental users, today announced the availability of KnowledgeTree Open Source Edition 3.5 licensed under the new GNU General Public License version 3. KnowledgeTree Open Source Edition 3.5, available immediately from the KnowledgeTree website, introduces powerful new Web Services-accessible document search functionality based on the Apache Lucene project, full PHP 5 compatibility and support for Microsoft Windows Vista.

    "The new GNU GPL version 3 is modern, well-structured and a significant achievement for the Free Software Foundation. We believe that it will provide a strong mechanism for the KnowledgeTree open source community to co-create and share document management functionality," said Daniel Chalef, KnowledgeTree COO.

    The GPL, published by the Free Software Foundation, is an Open Source Initiative-approved license and one of the most widely utilized free and open source software licenses. The KTForge is the place to go to find community contributed functionality such as plugins and language packs or to start your own KnowledgeTree community project.

    "The OSI is pleased to see KnowledgeTree adopting an OSI-approved license, the GNU General Public License version 3, for their upcoming product release. KnowledgeTree joins a growing number of companies who recognize the benefits of the open source model and who recognize that adopting an OSI-approved license strengthens both the open source community and their position as members of our community," said Michael Tiemann, President of the Open Source Initiative.

    KnowledgeTree is used by small and big business alike - users include Fortune 500 companies, community organizations, local and state governments, and educational, medical and scientific organizations around the world.
