Domain object hierarchies inducing multi-level models

Abstract Conceptual modeling of domain object hierarchies, such as product hierarchies or organization is difficult due to the intricate nature nonphysical objects organized in hierarchies. Modeling part-whole covers their hierarchical structure, yet capture meaning, have be combined with specialization and multi-level instantiation. To this end we introduce deep (DDO) pattern approach. With DDO approach, subclasses metaclasses are induced by integrated hierarchy. The approach aligned theory (MLT) formalized a metamodel set deductive rules implemented F-Logic. proof-of-concept prototype used for automated application querying models.
