- Think of well known in traditional ontologies:
- use the term "mammal"
- "every dog is a mammal"
- "Attila is a dog"
- RDFS defines the terms of resources and
classes:
- everything in RDF is a "resource"
- "classes" are also resources, but ...
- they are also a collection of possible resources (i.e.
individuals), as, for example: "mammal", "dog"
- Relationships are defined among classes/resources:
- "typing": an individual belongs to a specific class
(e.g.: "Attila is a dog")
- "subclassing": instance of one is also an instance of the
other
(e.g.: "every dog is a mammal")
