inheritance: The ability of classes to derive characteristics from other classes and properties to derivecharacteristics from other properties.If characteristics are removed from a class or property, they are alsoremoved from its subclasses or subproperties. See also: class; multiple inheritance; property; subclass;subproperty.
intention: The intended meaning of a class or property. The intention consists of the commoncharacteristics shared by all instances of the class or property. The intention need not be explicitlyformulated as properties in the case of a class or as the domain and range in the case of a property. Instead,the intention can be described in a scope note that refers to a conceptualization shared by domain experts.See also: class; class instance; domain; property; property instance; range; scope note.
mapping: An ontology of an aggregation format that relates the aggregation format’s classes andproperties to the classes and properties of another ontology. See also: aggregation format.
multiple inheritance: The ineritance of characteristics by a class from more than one immediatesuperclass or by a property from more than one immediate superproperty. If multiple inheritance is used,the resulting class or property hierarchy is a directed graph, not a tree structure. If multiple inheritance in aclass or property hierarchy is represented as an indented list, then some classes or properties will inevitablybe repeated at different positions in the indented list. For example, “person” could be a member of both theclasses “critic” and “author,”and, therefore,would be repeated at different positions in the indented list.This feature distinguishes an ontology from a simple tree structure. See also: class; inheritance; property;superclass; superproperty.
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 parentchild relationships between superpropertiesand their subproperties. Like a class, a property is characterized by an intention,which is conveyed by ascope note. See also: class; 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)[B8] ontology according to the Terse RDF TripleLanguage (Turtle) or Resource Description Framework/Extensible Markup Language (RDF/XML)syntaxes.14
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.
