A concrete realization of an InformationObject, e.g. the written document (object) containing the text of a law, a poetry reading (event), the dark timbre (quality) of a sound (event) in the execution (event) of a musical composition, realizing a 'misterioso' tempo indication. The realization of an information object also realizes information about itself. This is a special semiotic feature, which allows to avoid a traditonal paradox, by which an information is often supposed to be about itself besides other entities (e.g. the information object 'carpe diem' is about its meaning in Horace's Odes (let alone its fortune in Western culture and beyond), but also about its expression in context: 'dum loquimur, fugerit invida aetas: carpe diem, quam minimum credula postero', with the sound and emotional relations that it could activate. This is expressed in OWL2 with a local reflexivity axiom of the dul:InformationRealization class.
