Comments

  • Characteristics of a particular Dataservice that do not vary across Distributions that can be requested from the DataService are considered properties (has_property) of the Dataservice. In contrast, information needed in addition for requesting a particular Distribution are considered an access request parameter (has_parameter). Such parameters can be declared for a DataService, and provided for a particular Distribution via a dedicated QualifiedAccess relation.

TODOs

  • Enable indication what kind of credentials are required for access, and where to obtain them.

    - If the distribution(s) are accessible only through a landing page (i.e., direct
      download URLs are not known), then the landing page link SHOULD be duplicated
      as `dldist:access_url` on a distribution.

      a quality, capability, disposition, function, or is an externally derived attribute
      determined from some descriptor (e.g. a quantity, position, label/identifier).
      Technically, this declaration is done via an `AttributeSpecification` that combines
      a `predicate` with a value declaration and the attribute-related slots of a
      `Thing`. Importantly, such attributes are declared inline, because they do not
      have a unique identifier. If an identifier is available, a `Thing` declaration
      (see `relation`), and a qualification of that relationship via a `Statement`
      (see `is_characterized_by`) should be preferred.
