Sun Microsystems bought StarDivision in 1999. On 13 October 2000, Sun open sources StarOffice 6.0. On 14 October 2000, the OpenOffice.org project begins (OpenOffice was already a registered trademark). It is a full-featured office productivity suite:
- Writer: word processor,
- Calc: spreadsheet,
- Impress: presentation manager,
- Draw: drawing program,
- Database with ODBC or JDBC,
- Integrated documentation.
Good read/write compatibily with Microsoft Office file formats (better than Office itself for older versions), and a similar interface. Macros are not lost (they are commented out), but must be rewritten to be used in OpenOffice.org.
