Mappings RDB Ontology Shangguan 2

Question is for the Presentation: Joshua Taylor presents Discovering Simple Mappings Between Relational Database Schemas and Ontologies
Question is asked by: Zhenning Shangguan
The Question is: In Section_4.2, the paper gave Formulae (3) to create the virtual document for Classes in Ontologies, and stated that "In brief, for a class, its virtual document is its local description..." However, there are usually a variety of ways to define classes in an ontology, e.g., using equivalentClass, disjointClass, etc. Is it still appropriate to say that VD(C) = Des(C) if class C is defined by equivalance or disjointness?
