| nrl:Configuration | "Represents a named graph containing configuration data" |
| nrl:Data | "An abstract class representing all named graph roles" |
| nrl:DefaultGraph | "Represents the default graph, the graph which contains any triple that does not belong to any other named graph" |
| nrl:DiscardableInstanceBase | "A named graph containing instance data that can be recreated by analyzing the original resources. Intended to be used by metadata extractors." |
| nrl:DocumentGraph | "A marker class to identify named graphs that exist within a physical document" |
| nrl:ExternalViewSpecification | "Represents an external view specification, this usually being a program which automatically generates the required view for an input graph" |
| nrl:FunctionalProperty | "A marker class to identify functional properties" |
| nrl:Graph | "Represents a named graph" |
| nrl:GraphMetadata | "Represents a special named graph that contains metadata for another graph" |
| nrl:GraphView | "Identifies a graph which is itself a view of another named graph" |
| nrl:InstanceBase | "Represents a named graph containing instance data" |
| nrl:InverseFunctionalProperty | "A marker class to identify inverse functional properties" |
| nrl:KnowledgeBase | "Represents a named graph containing both schematic and instance data" |
| nrl:Ontology | "Represents a named graph having the role of an Ontology" |
| nrl:ReflexiveProperty | "A marker class to identify reflexive properties" |
| nrl:RuleViewSpecification | "Represents a view specification that is composed of a set of rules which generate the required view from the input graph upon firing" |
| nrl:Schema | "Represents a named graph containing schematic data" |
| nrl:Semantics | "Represents some declarative semantics" |
| nrl:SymmetricProperty | "A marker class to identify symmetric properties" |
| nrl:TransitiveProperty | "A marker class to identify transitive properties" |
| nrl:ViewSpecification | "Represents a specification of the means to achieve a transformation of an input graph into the required graph view" |
| nrl:cardinality | "Specifies the precise value cardinality for a specific property" |
| nrl:coreGraphMetadataFor | "Links a metadata graph to the graph for which it specifies the core graph properties including the semantics and the graph namespace. A graph can have only one unique core metadata graph" |
| nrl:defining property | "A defining property's value is part of what defines a resource, changing it means
means chaning the identity of the resource. The set of values of all defining
properties of a resource make up its identify.
Whenever comparing resources or sharing them the value of this property should
be taken into account. By default all properties with a literal range are to be
treated as defining properties unless they are marked as nrl:NonDefiningProperty." |
| nrl:equivalentGraph | "Links two equivalent named graphs. A symmetric property" |
| nrl:externalRealizer | "Points to the location of the realizer for the external view specification" |
| nrl:graphMetadataFor | "Links a metadata graph to the graph that is being described. A unique value is compulsory" |
| nrl:hasSemantics | "Points to a representation of the declarative semantics for a graph role" |
| nrl:hasSpecification | "Points to the representation of the view specification required to generate the graph view in question" |
| nrl:imports | "Models a subsumption relationship between two graphs, stating that the object graph is imported and included in the subject graph" |
| nrl:inverseProperty | "Links two properties and specifies their inverse behaviour" |
| nrl:maxCardinality | "Specifies a maximum value cardinality for a specific property" |
| nrl:minCardinality | "Specifies a minimum value cardinality for a specific property" |
| nrl:non-defining property | "A non-defining property's value is not part of what defines a resource, it rather
is part of the resource's state or expresses an opinion about the resource. Whenever
comparing resources or sharing them the value of this property should not be taken into
account. By default all properties with a resource range are to be treated as
non-defining properties unless they are marked as nrl:DefiningProperty." |
| nrl:realizes | "Points to a representation of the declarative semantics that the view specification realizes" |
| nrl:rule | "Specifies rules for a view specification that is driven by rules" |
| nrl:ruleLanguage | "Specifies the rule language for a view specification that is driven by rules" |
| nrl:semanticsDefinedBy | "Points to the human readable specifications for a representation of some declarative semantics" |
| nrl:subGraphOf | "Specifies a containment relationship between two graphs, meaning that the subject graph is included in the object graph" |
| nrl:superGraphOf | "Specifies a subsumption relationship between two graphs, meaning that the object graph is included in the subject graph" |
| nrl:updatable | "A core graph metadata property, this defines whether a graph can be freely updated '1' or otherwise '0'" |
| nrl:viewOn | "Points to a graph view over the subject named graph" |
