#####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>
Person type Class ;
Person subClassOf Resource ;
Person label "Person" ;
Person isDefinedBy "http://example.org/schema#"/ ;
#####
#####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.
