Error List for the domain-specific verification

The following errors are generated during the compliance check of a schema.org annotation/RDF-Graph based on the constraints defined by a Domain Specification.

Error Codes for the DS verification (start with 5)

ErrorCode	Name	Severity	Description
500	Generic compliance verification error	Any	Can be used as super-type for any error regarding the compliance verification
501	Non-conform target @type	Error	Annotation has a @type not specified by the DS - Applies to the @type of the root object
502	Non-conform property	Warning or Error	Annotation has a property that is not specified by the DS. The occurrence and severity of this error depends on the use of sh:closed: false -> no error. true -> error. not used -> warning
503	Missing property	Error	Annotation has a missing property that is defined as required by the DS
504	Non-conform cardinality	Error	Annotation has a property with a cardinality (amount of values), that is non-conform to the DS
505	Non-conform range	Error	Annotation has a property with a @type/datatype that is non-conform to the DS
506	Non-conform enumeration value	Error	Property has an enumeration value that is non-conform to the DS
511	Non-conform sh:maxLength	Error	String value has length that is greater than allowed
512	Non-conform sh:minLength	Error	String value has length that is smaller than allowed
513	Non-conform sh:pattern	Error	String value does not match the specified Regex Pattern
514	Non-conform sh:languageIn	Error	String value does not use any of the specified language tags
515	Non-conform sh:uniqueLang	Error	Property has string values that use the same language tag
521	Non-conform sh:minExclusive	Error	Numeric value is smaller than allowed
522	Non-conform sh:minInclusive	Error	Numeric value is smaller than allowed
523	Non-conform sh:maxExclusive	Error	Numeric value is greater than allowed
524	Non-conform sh:maxInclusive	Error	Numeric value is greater than allowed
531	Non-conform sh:equals	Error	Value of property is not equal to the value of the other property specified
532	Non-conform sh:disjoint	Error	Value of property is equal to the value of the other property specified
533	Non-conform sh:lessThan	Error	Value of property is not smaller than the value of the other property specified
534	Non-conform sh:lessThanOrEquals	Error	Value of property is not smaller or equal than the value of the other property specified
535	Non-conform sh:in	Error	Value of property does not match any value of the given list
536	Non-conform sh:hasValue	Error	Value of property does not contain the given value
537	Non-conform ds:hasLanguage	Error	Value of property does not use the given language

Semantics for Class Matching

In the following our understanding of the class-subclass relationship is explained.This relationship is important to determine valid matches for sh:targetClass / sh:class and ds:subDSOf.

A set of classes 'SubDS' is a valid match for another set of classes 'SuperDS' if all elements in 'SuperDS' are also present in a set that contains all elements from 'SubDS' along with all their superclasses:

classes(SuperDS) ⊆ superclasses(classes(SubDS))

The following table gives examples for this.

	Domain Specification	Data	Match
	sh:targetClass / sh:class	@type
exact match	LodgingBusiness	LodgingBusiness	yes
additional type	LodgingBusiness	LodgingBusiness, Product	yes
sub-type	LodgingBusiness	Motel	yes
no relation	LodgingBusiness	CreativeWork	no
exact match	LodgingBusiness, Product	LodgingBusiness, Product	yes
additional type	LodgingBusiness, Product	LodgingBusiness, Product, CreativeWork	yes
sub-type	LodgingBusiness, Product	Hotel, Product	yes
sub-type	Organization, Place	Restaurant	yes
not all types	LodgingBusiness, Product	LodgingBusiness	no
no relation	LodgingBusiness, Product	CreativeWork	no
