The DCAT RDF representation has a lot of documentation captured as text in vann:usageNote elements.
This is incorrect, as it is a sub-property of rdfs:seeAlso - see http://vocab.org/vann/#usageNote.
rdfs:seeAlso is an owl:ObjectProperty so cannot have a Literal value.
Also, the VANN vocabulary is no longer available in RDF (I can't find it anyway).
Proposal: replace vann:usageNote with skos:scopeNote throughout
In the RDF representation of SKOS the definition of scopeNote is "A note that helps to clarify the meaning and/or the use of a concept."
