The different cases to validate in the DCAT-AP Validator are based on the level of completeness of the checks and the incorporation of background knowledge (vocabularies). Each case is designed for a specific data exchange scenario.
The following describes each case and recommends which one you should use for a CKAN catalog:
Case 1: DCAT-AP Base Zero (no background knowledge)
Includes all constraints required for technical coherence, excluding range class membership constraints and controlled vocabulary usage.
For most use cases, Case 3: DCAT-AP Base (with background knowledge) is recommended. It provides comprehensive validation of basic coherence and vocabulary standards compliance.
If your CKAN catalog uses controlled vocabularies, consider using Case 6: DCAT-AP Controlled Vocabularies or Case 7: DCAT-AP Full (with background knowledge) for more exhaustive validation.
Remember, the choice of the appropriate validation case depends on your specific needs and data exchange context.

Case 3: DCAT-AP Base (with background knowledge)is recommended. It provides comprehensive validation of basic coherence and vocabulary standards compliance. If your CKAN catalog uses controlled vocabularies, consider usingCase 6: DCAT-AP Controlled VocabulariesorCase 7: DCAT-AP Full (with background knowledge)for more exhaustive validation.
