property: A characteristic that defines a relationship of a specific kind between two classes or sets ofclasses. A property has exactly one domain and one range. Which classes are selected as the domain andwhich as the range is arbitrary. In other words, a property can be interpreted in both directions with twodistinct but related interpretations.Property names are designed to be semantically meaningful andgrammatically correct when read from domain to range. Inverse property names are designed to besemantically meaningful and grammatically correct when read from range to domain.Properties can also bespecialized in the same manner as classes,resulting in parent/child relationships between superpropertiesand their subproperties. Like a class, a property is characterized by an intention，which is conveyed by ascope note. See also: class; class instance;domain; intention;range; scope note; subproperty;superproperty.
property instance: An instantiation of a property that defines the domain and range of a relationshipbetween two classes or sets of classes.For example, class X may be “containedBy” another class Y.In thisexample, “containedBy” is the instantiation of the property. The inverse property in this example would be“contains,” i.e., class Y“contains” class X. See also: class; domain; property; property instance; range.
range:The set of instances of a given class to which a property can be applied.For example, the range ofproperty A might consist of those instances of class X and class Y that exhibit property A. A property canlink only to instances of the classes that serve as its range. See also: class; class instance; domain;property.
representation: A method or syntax for serializing data.For example,it can refer to the differentserializations of a Web Ontology Language (OWL) [B1l] ontology according to the Terse RDF TripleLanguage (Turtle) or Resource Description Framework/Extensible Markup Language (RDF/XML)syntaxes.
resource aggregation: (A) Digital resources of diverse types that are gathered together to form a newcomplex object. Information is contained in the resource aggregation for purposes of specifying thecategories of and the relationships among the aggregated resources.A resource aggregation may becontained in an exchange file or not，and may be self-contained or reference resources held in otherlocations. A resource aggregation may be disaggregated into its component digital resources.Resourceaggregations are stored and processed using system formats (internal representations) and are usuallytransmitted between systems using aggregation formats. See also: aggregation format; digital resource.(B) The process of aggregating digital resources so that the result can be used in one or more applications,such as transmission, storage,and delivery to users.See also: digital resource.
scope note: A textual description of the intention of a class or property.Scope notes are not formalconstructs but are provided to help explain the intended meaning and application of classes and properties.See also: class; intention; property.
strict inheritance: The inheritance of characteristics by classes or properties that allows no exceptions. Seealso: class; inheritance; property.
subclass: A specialization of a class by inheritance from one or more superclasses. A subclass inherits allthe properties of its superclasses (i.e., strict inheritance) in addition to having zero or more additionalproperties of its own. If a subclass inherits properties from more than one superclass,it is said to havemultiple inheritance.See also: class; inheritance;multiple inheritance; property; strict inheritance;subclass; superclass.
subproperty: A specialization of a property by inheritance from one or more superproperties.All instancesof a subproperty are also instances of its immediate superproperty.The intention of a subproperty extendsthe intention of its immediate superproperty，i.e. its characteristics are more restrictive than that of itssuperproperty.See also: inheritance; intention; property instance; superproperty.
