GNOME Office
GNOME Office is a free office suite for the GNOME desktop. In contrast to projects like OpenOffice.org and KOffice, the integration between the various applications in the suite is rather loose. Therefore, GNOME Office could be considered to be merely the collection of desktop productivity applications written for the GNOME environment rather than an office suite in the usual sense.
As a consequence of this, it is not completely clear which applications are part of GNOME Office. According to the GNOME wiki, GNOME Office consists of the following core applications:
AbiWord word processor
Evince document viewer
Evolution groupware and e-mail application
Gnumeric spreadsheet
Inkscape vector graphics editor
Ease presentation tool (recently initiated project)
