Differences between StarOffice and OpenOffice.org
The source code available at OpenOffice.org does not consist of all of the StarOffice code. This is because Sun Microsystems, Inc. pays to license third party code to include in StarOffice that it does not have permission to make available in OpenOffice.org. Those things which are or will be present in StarOffice but are not available on OpenOffice.org include the following:
- Certain fonts, especially Asian language fonts, are not included
- The database component (Adabas D) is not included. The OpenOffice.org community is working on a way to use any database you want in the Database Access Component: http://dba.openoffice.org/
- Some templates and an extensive Clip Art Gallery,
- The Asian versions of OpenOffice.org lack some of the same sorting functionality,
- Certain file filters such as WordPerfect. There is a community project underway at the moment to write Open Source filters for including in OpenOffice.org:
File extensions
filename.sxw - OpenOffice Writer format (replaces Microsoft Word .doc)
filename.sxc - OpenOffice Spreadsheet (replaces Microsoft Excel .xls)
filename.sxi - OpenOffice Presentation (replaces Microsoft Powerpoint .ppt)
