- 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)
- Relationships are defined among classes/resources:
- “typing”: an individual belongs to a specific class
- “subclassing”: instance of one is also the instance of the other
- a bit like in object-based programming…
- …but the same resource can have several types
