Hi Gregg,
I'm doing something wrong trying to add a triple whose object is a
list. Basically what I'm trying to create is:

    :s :p (1 2 3).

Here's what I tried:

2.0.0-p247 :003 > r = RDF::Repository.new
 => #<RDF::Repository:0x15b1ac0()>
2.0.0-p247 :004 > l = RDF::List[1,2,3]
 => #<RDF::List:0x16b6cf4(RDF::List[1, 2, 3])>
2.0.0-p247 :005 > s = RDF::Resource.new("http://example.org/s")
 => #<RDF::URI:0x18d91f8(http://example.org/s)>
2.0.0-p247 :006 > p = RDF::Resource.new("http://example.org/p")
 => #<RDF::URI:0x1abcd1c(http://example.org/p)>
2.0.0-p247 :007 > r << [s,p,l]
 => #<RDF::Repository:0x15b1ac0()>
2.0.0-p247 :008 > r.dump(:turtle)
 => "\n<http://example.org/s> <http://example.org/p> _:g24109960 .\n"
2.0.0-p247 :009 > r << l
 => #<RDF::Repository:0x15b1ac0()>
2.0.0-p247 :010 > r.dump(:turtle)
 => "\n<http://example.org/s> <http://example.org/p> _:g24109960
.\n\n(1 2 3) a <http://www.w3.org/1999/02/22-rdf-syntax-ns#List> .\n"

I'm sure I'm doing something dumb, but I'm not sure what to change. Suggestions?

Thanks,
Ian
