Flexible Cardinality

[pmualaba]

Hello, i just succesfully installed structr. I am building a schema, but in the Cardinality fields of the relation, you can only enter 1 or *. This is the typical cardinality we have in relational databases. But now that we have a graph database available, I would like to enter a minimum:maximum:default cardinality.
Simple example: Car-[HAS]->Door i would like to set the cardinality for the Car-[HAS]->Door relation to 0:4:5 indicating that i can remove all doors of a Car instance (min cardinality is 0), and that i cannot create more then 5 Door instances for any given Car (max cardinality is 5). Also when creating a new Car instance (when Automatic Creation of Related Nodes is active) structr should automatically create the 4 Door instances (default cardinality is 4)
Is it possible to model this kind of behaviour in structr?

Kind regards.

Today, Structr only provides 1 or *, but extending this to more complex patterns is an interesting idea. I've added the appropriate labels so it will be tracked on our roadmap.
