In the wider sense, this class includes expressions of psychological value such as non-figural art and musical themes. However, conceptual items such as types and classes are not instances of E89 Propositional Object. This should not be confused with the definition of a type, which is indeed an instance of E89 Propositional Object.\n\nExamples:\n- Maxwell's Equations\n- The ideational contents of Aristotle's book entitled 'Metaphysics' as rendered in the Greek texts translated in \u2026 Oxford edition\u2026\n- The underlying prototype of any \"no-smoking\" sign (E36)\n- The common ideas of the plots of the movie \"The Seven Samurai\" by Akira Kurosawa and the movie \"The Magnificent Seven\" by John Sturges\n- The image content of the photo of the Allied Leaders at Yalta published by UPI, 1945 (E38)\n\nIn First Order Logic:\nE89(x) \u2283 E28(x)"@en . @prefix xsd: . @prefix skos: . ecrm:E89_Propositional_Object skos:notation "E89"^^xsd:string . _:b34670 rdf:type owl:Restriction ; owl:onProperty ecrm:P67i_is_referred_to_by ; owl:someValuesFrom ecrm:E1_CRM_Entity . _:b34671 rdf:type owl:Restriction ; owl:onProperty ecrm:P129i_is_subject_of ; owl:someValuesFrom ecrm:E1_CRM_Entity . _:b34672 rdf:type owl:Restriction ; owl:onProperty ecrm:P148_has_component ; owl:someValuesFrom ecrm:E89_Propositional_Object .
