sh:severity for SPARQL-based constraints

[Sebastian Thelen]

Hi, 

I'm trying to change the severity level for SPARQL-based constraints from their default value sh:Violation to sh:Warning. The way I'm trying to achieve this is as follows:

cdm:manifestation_court-report
        a                   rdfs:Class , sh:NodeShape ;
        rdfs:subClassOf     cdm:manifestation_print ;
        dash:closedByTypes  true ;
        sh:property         [ sh:maxCount  "1"^^xsd:nonNegativeInteger ;
                              sh:path      cdm:manifestation_court-report_belongs_to_type_court-report
                            ] ;
        sh:sparql           [ a            sh:SPARQLConstraint ;
                              sh:message   "Concept has to be equivalent to <http://publications.europa.eu/ontology/cdm#type_court-report>" ;
                              sh:prefixes  cdm: ;
                              sh:select    "SELECT $this ?value WHERE {$this <http://publications.europa.eu/ontology/cdm#manifestation_court-report_belongs_to_type_court-report> ?value.\n            FILTER NOT EXISTS {?value skos:inScheme ?conceptScheme.\n                               ?conceptScheme ^owl:hasValue/^owl:equivalentClass/rdfs:subClassOf* <http://publications.europa.eu/ontology/cdm#type_court-report> }}" ;
                              sh:severity  sh:Warning
                            ] .

Unfortunately, when there is a validation issue, the issue is still reported as "resultSeverity" : "shacl:Violation". Is there any way to do this? Chaning the severity level for non-SPARQL-based constraints seems to work, e.g., for cdm:manifestation_court-report_belongs_to_type_court-report.

Cheers, 

Sebastian

Hi Sebastian,

sh:severity is only supported for shapes, but the sh:sparql constraint is not a shape. You can either move the sh:severity triple into the manfestation_court-report shape (but then it would also apply to the other constraints), or create another shape with the same target, e.g.

cdm:manifestation_court-report_Warnings
	a sh:NodeShape ;
	sh:targetClass cdm:manifestation_court-report ;
	sh:severity sh:Warning ;
	sh:sparql [
		...
	] .

Hi Holger, 

thanks for your prompt reply. Moving sh:severity to manfestation_court-report is not an option for me as all other constraint violations still need to be treated as sh:Violations. Therefore I will try to generate a new shape just as you suggested.
