Subject: Re: How can I form a class tree from a rdfs/rdf file?

For example, there are statements or triples about class in a *.rdf 
or *.rdfs file.
Just like, 
<rdf:Class rdf:about="http://example.org/schema#Person">
  <rdfs:isDefinedBy rdf:resource="http://example.org/schema#"/>
  <rdfs:label>Person</rdfs:label>
  <rdfs:subClassOf 
    rdf:resource="http://www.w3.org/2000/01/rdf-schema#Resource"/>
</rdf:Class>

These classes and subclasses in the file just  form a tree or several
trees.
I wonder if there are any methods to get such a tree.
