changes to a concept not reflected in all subtrees about thesaurex HOT 5 CLOSED

I'm currently working on this one and the results looking good for

• Context menu > Add new concept
• Add broader concept
• Add narrower concept

But what should happen after one deletes a concept using the options from the context menu?

1. Delete concept and descendants
2. Delete concept and move descendants one level up
3. Delete concept and move descendants to the top level

My idea for 1. was to remove the concept completely, which would be easy to implement. But I couldn't think of a good behaviour for 2. and 3. Do you have any idea @dirkseidensticker @AngusLeBoeuf ?

As there are hypothetical use cases for this, I would suggest the following:

• in any case there should be a warning, stating that deleting a concept that has multiple broader or narrower concepts results in the following ...
• this warning must be accepted "'yes' i will delete them'
• cases:
  1. is good as you proposed
  2. should only work on the selected element in the tree (the one you clicked)
  3. is not necessary and can be removed

I encountered several problems with our ideas.

One problem is your case 2 for an element as 'Textilverarbeitung'.

Example

• Path 1: Fund > Artefakt > Form > Werkzeug > Textilverarbeitung
• Path 2: Facetten > Artefakt (thematisch) > Werkzeug > Textilverarbeitung
  It has only one parent ('Werkzeug'), but 'Werkzeug' has two parents. Thus, moving the children of 'Textilverarbeitung' in Path 1 would move them in Path 2 as well.

Another problem is ('Textilverarbeitung' again) that the current implementation for an element with one parent, but two parents can not compute the exact path to this element in the tree.

We should discuss this in person next week.

Thanks to #63 I think this has been fixed. Can someone confirm this please? @eScienceCenter/spacialists
