Where #4 is concerned with providing multiple Describers for a single RDF type, we will also almost always be presented with a situation where an object being described has multiple RDF types (e.g. a Human is-a Mammal)
The interesting part of this problem is knowing when we want to pipe something - e.g. if I describe a character's personality it's probably enough without describing them in the capacity of being a living organism, but if it's the first time I've seen an alien species then interpreting their personality is a bit much to ask. The context in which I'm describing them is quite important
