the relationship is this:

Each Plasma::Containment may have a Plasma::Context associated with it
Each Plasma::Context object aggregates an Activity, the current geolocation \
information, etc.

The Activity is recorded in Nepomuk so that other applications can use them as well. \
The Activity has a name (for the user) and an ID (for info retrieval purposes).

At any given time zero or one Activity is the "current" activity.

plasma-desktop will need to map what it is showing in its Views using this \
informtion; e.g. when Activity Y is marked as the current activity in Nepomuk, it may \
want to switch to showing the Containment(s) where \
Containment::context()->activityId() == \
GlobalContext::currentActivity()->activityId(). (or whatever the API ends up being).

or plasma-desktop may decide to set the current Activity in nepomuk to whatever \
Containment the user just selected to focus on in the overview mode.

meanwhile, Kopete / Konqueror / Kontact / etc / etc may also choose to watch for the \
Activity in Nepomuk and alter what they are doing in response. They may also decide \
to create new Activities of their own, which plasma-desktop may elect to follow or \
ignore.

HTH.
