Why is the class written as rdfs: Class and the property is written as rdf: Property

There are many examples of this.

Among many, we can consider this .

Above said

  • rdfs: a class declares a resource as a class for other resources.
  • rdf: Property is a class of properties.

Now, my question is: why is the class considered to be definable in the RDF schema and the property is considered simple RDF.

The reason is purely historical. The RDF model was defined before the RDF schema appeared, and it already contained the vocabulary term for the concept of a property, so rdf:Property is part of the RDF namespace.

The concept of explicit classes was first introduced in the RDF schema, so it became rdfs:Class .
