Creating relations between classes in ontology editor can be simplified

[joepio]

In Atomic Data, you can set the datatype of a property to resource or resourceArray to make it a relation between multiple resources. In UML diagrams, that is the arrow.

This concept can be a little daunting for new users who are building their own ontology. I think we may need to change the UX.

In notion, you can select a relation datatype, and then a dialog lets you select another class. After that, you can set a limit (to 1 or no limit).
