Having the terms of the Humboldt extension declared as RDF properties

[bcogrel]

When downloading the dump of DwC, the terms are declared as RDF properties or RDFS classes (#357).

curl http://rs.tdwg.org/dump/terms.ttl

<http://rs.tdwg.org/dwc/terms/year>
# ...
     rdf:type <http://www.w3.org/1999/02/22-rdf-syntax-ns#Property>;

However, for the Humboldt extension, the terms are not "typed" as RDF properties or RDFS classes:

curl http://rs.tdwg.org/dump/humboldt.ttl

or

curl http://rs.tdwg.org/dump/humboldt_iri.ttl

Would it be possible to have the export typing them?
