Currently, the output of Special:EntityData/Q23.ttl claims that George Washington is a Wikibase Item `<<entity:Q23 a wikibase:Item>>`, which is clearly false. Our //description// of George Washington is a Wikidata Item `<<data:Q23 a wikibase:Item>>`.
We should also consider (optionally) omitting these is-a statements, since they are extremely redundant.
Side node: this issue is reflected by the RDFS spec at the lowest level, which claims that //everything// is an rdfs:Resource:
> 2.1 rdfs:Resource
> All things described by RDF are called resources, and are instances of the class rdfs:Resource.
> This is the class of everything. All other classes are subclasses of this class. rdfs:Resource is an
> instance of rdfs:Class.
There does not seem a distinction between the //thing// and the //description// of the thing built into the rdfs spec. Can we go back 15 years and fix this?...
