This PowerPoint presentation explains the role which concepts from thesauri and taxonomies play in Linked Data. It briefly discusses ontologies in general before moving on to OWL (Web Ontology Language). Discusses the advantages and drawbacks of mixing vocabularies (e.g., OWL, RDFS, SKOS) and trade-offs between simplicity and expressivity. Focuses on the importance of not trying to force relationship types when they are not appropriate (e.g., "broader than" or "narrower than" when no hierarchy exists; "same as" when two objects are not exact matches).
