The Semantic Web Linked Data Digging Deeper into Linked Data Final Words
Making the Semantic Web Work—Ontologies OWL (and RDFS) provide ontologies for the Semantic Web Ontologies provide machine-processable meanings for (the names in) the data, particularly the categories and relationships Ontologies admit deduction of implicit information Humans also do this (but perhaps in very different ways)
