== Ideas for a query interface ==

=== Idea ===

We have a column with all the obects and apply a filter to get another column.

Filters could be
 * contains text (in any attribute)
 * contains text in a specific attribute
 * has certain object type
 * is directly related (to the (selected) objects)
   * not selecting anything and creating another column gives everything 2nd degree related 
 * is indirectly related (by a path)

The column is divided by object type.
 * clicking on an object type selects the type as a filter

Unfolding the object type shows the selected instances.
 * clicking on the instance selects the instance (show the direct relations in the next column?)

It should be possible to select attributes to display in the column. (Default own-value?)

Some objects would have more complex display rules, e.g. Witness showing author and title (from text).
