Ideas for query interface

Faceted Browsing

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)
• is indirectly related (?)

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.
