Machine-readable metadata that describes a digital resource is available.
Rationale: This metric does not attempt to measure (or even define) "Richness" - this will be defined in a future Metric. This metric is intended to test the format of the metadata - machine readability of metadata makes it possible to optimize discovery. For instance, Web search engines suggest the use of particular structured metadata elements to optimize search. Thus, the machine-readability aspect can help people and machines find a digital resource of interest.
A URL to a document that contains machine-readable metadata for the digital resource. Furthermore, the file format must be specified.
