The DCAT subset is based on the DCAT-AP vocabulary for describing datasets and metadata in European data portals.

Domain
The shapes define constraints on metadata properties such as license, language, and publisher, often requiring values to link to controlled vocabularies. This subset notably includes nested constraints via sh:node, introducing multi-level validation dependencies.
Constraint patterns in this subset include:
- Metadata property constraints
- Links to controlled vocabularies
- Nested constraints via
sh:node - Mandatory and recommended fields

The DCAT-AP application profile is maintained by the Publications Office of the European Union and is widely used in European open data portals.
