"It is not meant for collaborative work, so if that is what you
need, a groupware solution is probably a better fit. But if all you
need is a personal organization tool or information manager, Osmo
will do the job nicely.
"Your distribution of choice may have Osmo pre-packaged and
ready to use with it being a simple yum or apt-get away. Once
installed and started, you see Osmo start in the Calendar view with
the current day circled. Beneath the calendar is a space for taking
notes — a handy place to jot down quick notes as they come to
"Each note pane is specific to the date of the calendar, so if
today was the 14th and you clicked on the 15th, any notes entered
in would no longer be visible, until going back to the 14th. A
little black tick on the calendar indicates those days that have
associated notes. If you need to use the note space as an agenda,
the clock icon will pre-fill out the note space with a timeline of
your specification: You define the start and end hours and the step
(in minutes) so you can have a timeline of every hour from 8 a.m.
to 5 p.m. if you like."
