RDF(S) Knowledge Base

Terminological Knowledge (T-box) consists of Classes and Properties as well as Relations between those Constitutes in RDFS.

Besides this there is also the Assertional Knowledge (A-box) based on RDF within the RDF Schema knowledge base.

@prefix rdf: ](http://www.w3.org/1999/02/22-rdf-syntax-nx#>)]
@prefix rdfs: ](http://www/.w3.org/2000/01/rdf-schema#>)]

:Course a rdfs:[Class](/blog/619/).
:Lecture a rdfs:[Class](/blog/619/);
     rdfs:subClassOf :Course.
:Seminar a rdfs:[Class](/blog/619/);
    rdfs:subClassOf :Course.

:Person a rdfs:[Class](/blog/619/) .
