| <p>This page describes support for accessing data with additional statements |
| derived using RDFS. It supports <code>rdfs:subClassOf</code>, <code>rdfs:subPropertyOf</code>, <code>rdfs:domain</code> and <code>rdfs:range</code>. It |
| does not provide RDF axioms. The RDFS vocabulary is not included in the data.</p> |
| <p>It does support use with RDF datasets, where each graph in the dataset has the |
| same RDFS vocabulary applied to it.</p> |
| <p>This is not a replacement for the <a href="/documentation/inference/#rdfs">Jena RDFS Reasoner support</a> |
| which covers full RDFS inference.</p> |
| <p>The data is updateable, and graphs can be added and removed from the dataset. |
| The vocabulary can not be changed during the lifetime of the RDFS dataset.</p> |
