That is correct. (It is not a Reproduce).

Yes.

Nope.

A payAmount can only be used in a Duty. See: http://w3c.github.io/poe/model/#duty <http://w3c.github.io/poe/model/#duty>

I assume the second  odrl:leftOperand is odrl:rightOperand?
You can now use odrl:rightOperandReference:  https://w3c.github.io/poe/vocab/#term-rightOperandReference <https://w3c.github.io/poe/vocab/#term-rightOperandReference>
for a value to be determined later.

The problem here is that the payAmount is an obligation on the assignee (I assume the dalic:contributors) - but you want them to charge the third-parties the amount ?
