Rdf correct use ? (anonResources everywhere ?)

Hi all,

I'm really thrilled by the RDF technology that i've just discovered 
these past weeks. As I'm quite new in XUL/XPCOM and all Rapid 
Application Development technologies around Mozilla, I've made lots of 
mistakes and will do some more.

Currently, I'm using memory datasources to generate lots of anonymous 
datasource to feed in Tree databases. For example, I've made a little 
test application that creates the subClassMap of the RDF Schema 
specification in RDF provided at the end of the corresponding page in 
the W3C website.

To do this, I must parse their RDF following the "subClassOf" property 
to collate them in a temporaly "Seq" element (an anonymous resource), 
optionnaly holding other "Seq" element to make a complete tree.

This seems quite speedy for the moment, but I fear that I could become 
really bloated by all the security management, QueryInterfaces, and 
recursive calls to make finally a structure that is Already existent... 
All this feel quite messy at the end...

Have I missed the correct way to display such trees ? Have you some 
suggestions ? How would you tackle this problematic ?

thx for your comments
