getRelevantProperties

public static java.util.List<com.hp.hpl.jena.rdf.model.Property> getRelevantProperties(com.hp.hpl.jena.rdf.model.Resource subject)

getRelevantProperties

public static java.util.List<com.hp.hpl.jena.rdf.model.Property> getRelevantProperties(com.hp.hpl.jena.rdf.model.Resource subject,
                                                                                       java.util.Set types)

getUnionDomainClasses

public static java.util.Set getUnionDomainClasses(com.hp.hpl.jena.rdf.model.Property property)

getUnionDomainProperties

public static java.util.Set<com.hp.hpl.jena.rdf.model.Property> getUnionDomainProperties(com.hp.hpl.jena.rdf.model.Resource cls)

Gets all properties that have a given class in their (direct) union domain.

Parameters:

cls - the class to get the properties for

Returns:

a Set of Properties

hasMatchingDomain

public static boolean hasMatchingDomain(com.hp.hpl.jena.rdf.model.Property property,
                                        com.hp.hpl.jena.rdf.model.Resource subject)

Checks if a property has a domain statement that matches one of the types of a given resource.

Parameters:

property - the property to analyze the domain of

subject - the resource that is expected to have a type from the domain

Returns:

true if the property has a matching domain

hasMatchingDomain

public static boolean hasMatchingDomain(com.hp.hpl.jena.rdf.model.Property property,
                                        com.hp.hpl.jena.rdf.model.Resource subject,
                                        java.util.Collection matchCache)

isDomainless

public static boolean isDomainless(com.hp.hpl.jena.rdf.model.Resource property)

Checks whether a property is domainless. A property counts as domainless if it either has no rdfs:domain statement attached, or only rdfs:Resource as its domain (this is common for some system properties).

Parameters:

property - the property to check the domain of

Returns:

true if property is domainless according to the definition above
