    61 result of the specification of a given data field

Digital objects can exist in databases, hence the comparison to directory and file structures falls short.
     50
     51 * metadata
     52   * A description of a __resource__, usually given as a set of properties in the form of attribute-value pairs. This description may contain information about the resource, aspects or parts of the resource and/or artefacts and actors connected to the resource.

     87 * Resource proxy, CMD resource reference
     88   * A representation of a __resource__ within a __metadata instance__ containing a __Uniform Resource Identifier__ as a reference to the resource itself and a specification of its type (one of: Resource, Metadata, !SearchPage, !SearchService, !LandingPage)
