The Aristotle Dataset Extensions (Aristotle-DSE) is a DCAT-compatible extension to the Aristotle Metadata Registry to provide metadata-aware data registry services.

Aristotle-DSE implements the W3C DCAT standard for describing dataset resources on the web and provides 2 additional objects with references described below

DataSetSpecification

Where a dcat:Distribution has an association to DataSetSpecification and number of DistributionDataElement objects, the details of the DistributionDataElement should be used for validation and quality purposes.
