Ok. This is the main idea:

The agent retrieves a specific resource.  This resouce comes in many
diffrent views.  The resource knows what properties is used for decide
the view.  Create a key from the combination of those criterions.
Match those against a table in the context from the criterion key to
the context key.  If none exist, create it (with dependencies).  The
value is the view key and can be used to find the right view in a
lookup table in the resource.

(I hade to write this down just to remember it.)


I previously saw each view as a separate resource.  They are separate,
but they have to be grouped in a way that separates the context
criterions from primary criterions.  The primary criterion are the
inclusive part of the search.  The other part, that gives the view, is
the filtering part.

Ok. This i vague.  But i believe that I have find the right path.


The details will have to waite.  Now it's time to continue
experimenting with dependency registration.
