[protege-owl] Intersections in protégé

Dear Kaarel,

You are right, the picture is quite vague. Sorry. Here I attached a better version of the picture.

As you can see:

Impact1 appears as the result of the intersection of  (Phase1 with Aspect2)  or  (Phase1 with Aspect3)  or  (Phase2 with Aspect1).

That is the same as: Impact1 takes places a long Phase1 when is only related to Aspect2 and Aspect 3 and, by the same way, Impact 1 takes place along Phase2 when is only related to Aspect1. 

How could this be implemented in Protégé? 

Thank you in advance,

Pictures are vague. It is not clear which relations are mandatory, which
optional, and which illegal.
Does the following text describe what you want?

Every type3-impact takes place along a type1-phase.
Every type3-impact takes place along a type2-phase.
No type3-impact takes place along a type3-phase.
Every type3-impact is related to a type1-aspect.
Every type3-impact is related to a type2-aspect.
Every type3-impact is related to a type3-aspect.

And additionally:

Every type1-impact is an impact.
Every type1-phase is a phase.
Every type1-aspect is an aspect.

And possibly also:

Every impact is a type1-impact or is a type2-impact or is a type-3-impact.
No type1-impact is a type2-impact.
