Schema Re-engineering Ontology Design Patterns (Schema Re-engineering OPs)
Schema reengineering patterns are rules for transforming from a model in one formalism to another.



Description

Schema reengineering patterns are rules for transforming, e.g. a non-OWL DL metamodel into an OWL DL ontology. For example, consider the use of SKOS for Knowledge Organization Systems (KOS) reengineering to a knowledge base (an OWL ABox), based-on the SKOS TBox. Transformation Logical OPs are a kind of schema reengineering patterns. In principle, all modeling problems can be represented as higher-order logical expressions, and if we have to represent them e.g. in OWL DL, we implicitly apply a schema reengineering pattern in order to stay within the expressivity of OWL DL. However, we also (pragmatically) distinguish between transformation and schema reengineering patterns because of the di�fferent intention of the designer. In the �first case, the designer wants to directly represent a modeling solution in a certain representation formalism, e.g. OWL DL, while in the second case the designer wants to reengineer, e.g. an existing non-OWL DL model into an OWL DL ontology.
