DCAT-AP Validator Validation Cases

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.

SHACL Profiles:

• 2.1.1
• 3.0.0

Case 2: DCAT-AP Ranges Zero (no background knowledge)

Includes all range class membership constraints.

SHACL Profiles:

• 2.1.1
• 3.0.0

Case 3: DCAT-AP Base (with background knowledge)

Extends Case 1 with background knowledge, including all vocabularies used in DCAT-AP.

SHACL Profiles:

• 2.1.1: shapes and imports
• 3.0.0: shapes and imports

Case 4: DCAT-AP Ranges (with background knowledge)

Extends Case 2 with background knowledge, adding validation of range class membership and vocabulary standards compliance.

SHACL Profiles:

• 2.1.1: range and imports
• 3.0.0: range and imports

Case 5: DCAT-AP Recommendations (with background knowledge)

Includes all constraints related to recommended properties.

SHACL Profiles:

• 2.1.1: shapes recommended and imports
• 3.0.0: shapes recommended and imports

Case 6: DCAT-AP Controlled Vocabularies

Includes all constraints related to controlled vocabularies.

SHACL Profiles:

• 2.1.1: vocabularies shape and imports
• 3.0.0: vocabularies shape and mdr imports

Case 7: DCAT-AP Full (with background knowledge)

The union of Cases 3, 4, 5, and 6.

SHACL Profiles:

• 2.1.1: shapes, shapes recommended, imports, range and deprecateduris
• 3.0.0: shapes, shapes recommended, imports, range and deprecateduris

Recommendation:

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.
