For the Semantic Web and Linked Data the Models are based on the use of RDF, RDFS, and OWL which are used to describe the tTypes, pProperties, and rRelationship tTypes. ¶

Ontologies are also commonly known as RDF "vVocabolaries". ¶

Ontology are cCollections of iInformations. The term Ontology is co-opted by Artificial- Intelligence and Web Researchers, in which an Ontology is a dDocument or fFile that formally defines the Relations among tTerms. The most typical kind of Ontology for the Web has a tTaxonomy and a set of iInference Rules.
