    rdfs:subClassOf ids:DescribedSemantically, ids:DigitalContent, # e.g., Collection Resource contains sub-resources but also has an own Representation
        ids:ManagedEntity, odrl:Asset ;
    rdfs:label "Resource"@en ;
    rdfs:comment "Resource is a single digital content or a coherent set of digital contents. Resource content is formalized in Representations and optionally materialized as Artifacts. The Resource's content is exposed via defined Interfaces at various protocol Endpoints."@en;
    rdfs:seeAlso <https://www.w3.org/TR/vocab-dcat/#class-dataset>;
.

    # As a single root of (a series of) content(s) Resource is the natural home for a "Data Structure Definition" (compare DQ)
    # See: https://www.w3.org/TR/vocab-data-cube#h2_dsd
    #
    # Likewise it may re-purpose and re-publish contents in a new meaningful collection, similarly to qb:ObservationGroup, "arbitrary collection of observations"
    #
    # Resource defines means to communicate the content (interface and endpoints), content per se is not "communicable"
    #
    # A Resource *must* define any content provided either statically or dynamically -> shortcut


# Properties
