http://www.w3.org/2000/01/rdf-schema#comment A metric might require a number of external resources (e.g. a gold standard) in order to be able to measure the quality. In order to cater for the most generic requirement, this property links a metric to the required resource (e.g. a URI to the gold standard dataset used).

http://purl.org/eis/vocab/daq#
http://purl.org/dc/elements/1.1/description The Dataset Quality Vocabulary (daQ) is a lightweight, extensible core vocabulary for attaching the result of quality benchmarking of a linked open dataset (usually an expensive process) to that dataset. daQ is designed to be extended by custom quality metrics. Use cases include filtering and ranking datasets by quality.

http://www.w3.org/2000/01/rdf-schema#comment The smallest unit of measuring a quality dimension is a metric. A metric belongs to exactly one dimension. Each metric has one or more observations (daq:hasObservation), which records data quality assessment value following a computation.
