    rdfs:comment "A Predication that reports a claim made by someone other than the source of the Opinion, and that is discussed or used inside the Opinion as evidence. It has no epistemic status: the attitude toward the reported claim belongs to the original source, and the Opinion's source commits only to the fact that the claim was made. This follows the distinction of the DOLCE epistemic layer and its observation ontology between accessing a report, which registers the point of view of its author while keeping track of the source, and interpreting it, which embraces that point of view. It is a primitive class, not a defined one, and it is disjoint from Assertion, Belief, Hypothesis and Conjecture, so a Predication that carries a status cannot also be a Reference. A reported claim that the source also adopts is a separate Predication with its own status, linked to the Reference with supports or evidences. Example: the statement of a previous cataloguer that a drawing is by artist A, reported to be weighed against the watermark."@en ;
