    rdfs:comment "A relation from an Opinion to the agent that authored it, shortcutting the provenance path Opinion - prov:wasGeneratedBy - Activity - prov:wasAssociatedWith - Agent. It is inferred by that property chain and it should not be asserted. The chain goes through prov:Activity and not only through hico:InterpretationAct, which is a subclass of it, so it holds for any activity that generated the Opinion. It assumes that the agents associated with the activity are its authors: an activity with other kinds of associated agents, such as a software tool, would make them authors too, and in that case the authors should be stated with a qualified association instead. It specialises prov:wasAttributedTo, so that PROV consumers see the attribution. Being implied by a chain, it is not a simple property and cannot be declared functional."@en ;
