StarOffice became Oracle Open Office in the acquisition of Sun by Oracle. It was the commercial version built from OpenOffice.org. As LibreOffice, Oracle Open Office proposed some extensions included during installation contrary to OpenOffice.org. Models and galleries were also provided by Oracle Open Office. In LibreOffice, you have to install it separately, eg using extensions. But the main difference was in the approach proposed by Oracle support. The Enterprise version had connection modules with other Oracle applications. Oracle ceased marketing Oracle Open Office in April 2011.
