<h2>Detailed Description</h2>
<p>\class Class class.h Nepomuk/Types/Class
</p>
<p>
A Class is a resource of type rdf:Class.
</p>
<p>
Class instances are explicitly shared. Two instances created
with the same uri reference the same data.
</p>
<p>
While Resource objects can be changed Class instances are considered
to be static and never changed during their lifetime.
