GNOME Office

• AbiWord
  
  A free word processing program. AbiWord has a comprehensive language database with multiple languages. It also has support for tables and footnotes, as well as a spell checker and an advanced grammar checking system. AbiWord has been chosen to be part of the One Laptop Per Child project.
• Gnumeric
  A free spreadsheet program. Gnumeric has the ability to import and export data in several file formats, including CSV, Microsoft Excel, HTML, LaTeX, Lotus 1-2-3, OpenDocument and Quattro Pro; its native format is the Gnumeric file format (.gnm or .gnumeric), an XML file compressed with gzip.
• Evolution
  The GNOME groupware application that combines e-mail, calendar, address book, and task list management functions.  Its user interface and functionality are similar to Microsoft Outlook. Features include, iCalendar support, full-text indexing of all incoming mail, powerful email filters writable in Scheme, and a "Search Folders" feature (i.e., saved searches that look like normal mail folders). Evolution can be connected to a Microsoft Exchange Server using its web interface. It may be synchronized with Palm Pilot devices, and OpenSync enables it to be synchronized with mobile phones and other PDAs.
• GNOME-DB
  The database application of GNOME Office. The project aims to provide a free unified data access architecture to the GNOME project for all Unix platforms. GNOME-DB is useful for any application that accesses persistent data (not only databases, but data), since it contains a data management API.
• Evince
  Document (PDF) viewer.

The Debian project includes additional applications in this list:

• Dia, diagram editor
• GIMP, raster graphics editor
• Inkscape, vector graphics editor
• XSane, graphical frontedn of scanner access
• Planner, project management tool

The integration between the various applications in the suite is rather loose, and therefore many consider GNOME Office to be merely the collection of desktop productivity applications written for the GNOME environment rather than an office suite in the usual sense. Integration is achieved chiefly through the Bonobo component technology.
