Resource isVersionOf only Resource missing?

[RendersKoen]

Hi,

according to

hasVersion dcterms:description "To identify another version of an Asset, EditorialObject or Resource."

but though there is a

isVersionOf only EditorialObject restriction to EditorialObject,

this seems to be missing in Resource, which I think is necesary.

(actually also missing on the Asset level, so maybe either it should move to there and inherited by EditorialObject and BibliograhicalObject, or Asset can be removed from the description of hasVersion

Am I at least right to assume that hasVersion and isVersionOf is also intended to relate Resources to one another?

in addition, I would add "hasVersionType only skos:Concept" to Resource, and extend the description to

"To specify a type of version for an EditorialObject or a Resource."
