UML class diagram when templated forms are involved

I'm learning UML diagramming and I am bit confused how to draw the class diagram for my problem

  • A Firm has many users
  • A User can belong to many firms
  • A Firm has many templated forms
  • A User can't create their own forms but can clone and use a Firm's templated forms

My questions:

  • It this UML diagram right?
  • Is Form split into 2 classes or is that unnecessary?
  • Or is there a better way of doing this?

This diagram is not wrong. I wonder however if there shouldn't be an association between the user form and the cloned template form.

There is an open question about whether a form template is also a form. Your short narrative seems to assume this. Another alternative could be to not let inherit FormTemplate from Form, but to prefer composition, by associating a Form to the FormTemplate. The cloning of a user form would then clone only the form information of the template and not the metadata that is only relevant for the template.
