As Lorenz says, your postings come through with all URLs duplicated so
it's hard to be sure what's actually in your data. However, things like:
<http://www.w3.org/1999/02/22-rdf-syntax-ns#rdf:type>
are wrong. Either use the correct URI:
<http://www.w3.org/1999/02/22-rdf-syntax-ns#type>
or use the prefix form:
rdf:type
