Metaclass (Semantic Web)

In the context of the Semantic Web, a *metaclass* is a concept that pertains to the model of classes and types in knowledge representation frameworks, particularly in ontology languages such as OWL (Web Ontology Language) and RDF Schema (RDFS). ### Key Points about Metaclasses: 1. **Definition**: A metaclass is a class whose instances are classes themselves. This is analogous to how a class in object-oriented programming defines the structure and behavior of its instances.
