Review Summary: This pattern is an extension of the W3C n-ary relationship in that a n-ary realtionship can be summarized in a simple relationship between two individuals.
I can image that querying a knowledge base is easier - however, I encourage the author to clarify and explain how this aim is achieved (give an example, etc.). However, there is one problem with the pattern and that's the name: the pattern does not describe an inverse n-ary relationship but a special kind of it where only two distinguished individuals are considered with "additional, and probably optional, argument".
