    rdfs:comment "A data property giving the degree of belief, between 0 and 1, that a source assigns to a claim, on a Predication, or to all the claims of a Predicative Content. It is functional: one confidence per Predication or Content. It is distinct from the epistemic status (the kind of commitment) and from hasCertainty (the kind and amount of uncertainty). The 0-1 bound is left to validation (SHACL) so that the range stays a plain datatype. Stated on a Predicative Content, the value is the default for every member that does not state its own; OWL cannot express a default that a member may override, so it is resolved in queries (see the competency questions) and not by the reasoner."@en ;
