Construct of classes

Hello,

i have this file (data+schema):
http://pastie.textmate.org/private/j0yyyh2yjastm7hdlaewg


I execute the following ruby-code:
adapter = ConnectionPool.add_data_source(:type =>
:redland,:location  
=> "./__db.rb",:want_new => true)
adapter.load "./rxml.nt","rdfxml"
Namespace.register(:test, 'http://www.As
sgiment1.com/schemas/lvas#')
classes = ObjectManager.construct_classes
puts classes.inspect
puts classes.first.find_all.length
puts TEST::lva.find_all.length


and the output is:
[<file:./rxml.nt#lva>]
0
NoMethodError: undefined method ‘length’ for nil:NilClass

Why is that? Is it a bug in Activerdf?
On another note: would it be even possible with activerdf to
resolve  
bags like i have it in my rdf-structure?

thanks in advance

Try with:

xml:base="http://
www.Assgiment1.com/schemas/lvas#"

Thank you that works.

but it seems that activerdf has the same problem with the
bags than i  
have manually.
how can i access the bags/collections ?

Sorry, ActiveRDF does not handle collections (yet). I'm open
to patches 
though.
