Find a way for (Interface)Concept*Relations to not be needed?

[eugenschindler]

Currently, my understanding of the Itemis diagram editor is that you need to have a concept for every edge and you need to have the proper to/from filled in, otherwise the edge is not shown in the graphical editor. Find a way (or check with Itemis if it needs to be added to the diagram editor) to have something like "querylist" for the graphical editor, where we can get away with having edges in the diagram without necessarily having corresponding concepts that have the to and from set.

I often model connectors as smart reference concepts these days.

• They have an obligatory reference to the target (cardinality 1)
• They are stored as children in the parent concept (i.e. children of the box in the graphical editor).
• Box view of the parent concept adds the children in the content field
• Edge editor on the smart reference uses
  box thisNode.parent as source
  box thisNode.ref as target (or whatever your reference field is called).

It would indeed be great if reference field in the parent concept could be turned into edges directly without the need for an intermediate concept with a smart reference.
