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.
