The domain and range of a property
The domain is the class for which a property is formally defined. This means that instances of the property are applicable to instances of its domain class. The range is the class that comprises all potential values of a property. That means that instances of the property can…
Properties are like grammatical verbs
A property serves to define a relationship of a specific kind between two classes. The property is characterized by an intension, which is conveyed by a scope note. A property plays a role analogous to a grammatical verb, in that it must be defined with reference to both its…
Intention of a class
The intension of a class or property is its intended meaning. It consists of one or more common traits shared by all instances of the class or property. These traits need not be explicitly formulated in logical terms, but may just be described in a text (here called a scope…

Typing resources with rdf:type
However, example.com will probably offer several different models of tents, as well as multiple instances of other categories of products, such as backpacks, hiking boots, and so on. This idea of things being classified into different kinds or categories is similar to the…
Communities need their own vocabularies
RDF provides a way to express simple statements about resources, using named properties and values. However, RDF user communities also need the ability to define the vocabularies (terms) they intend to use in those statements, specifically, to indicate that they are describing…
Rdf-compatible Model-theoretic Semantics For Owl
OWL Full versus OWL DL
All of the OWL vocabulary is defined on the 'OWL universe', which is a division of part of the RDF universe into three parts, namely OWL individuals, classes, and properties. The class extension of owl:Thing comprises the individuals of the OWL universe. The class extension of…
