This pattern is proposed to model Symmetri … This pattern is proposed to model Symmetric n-ary relationship by explicitly expressing that participating classes have the same attributes and values of these attributes; while avoiding redundancy representation.
the general problem addressed by this pattern (modeling issues) is not defined. Besides, the pattern is not explained neither presented as a generic solution. Solution description is not sufficiently convincing : do cardinality and equivalentClass axioms guarantee the purpose of the pattern?
Explanation, proof and implementation are missed. And this is very important when proposing an ODP to be reused.
the given example is not suitable as it is based on a symmetric binary-relationship. based on a symmetric binary-relationship.
