  use RDF::Redland::DIG::KB;
  my $kb = $r->kb;   # create an empty knowledge base there

Instances of this class represent a handle to a remote instance of a DIG reasoner.

DIG is a protocol which applications can use to use reasoning services provided by such a reasoner.

   http://dl-web.man.ac.uk/dig/

The constructor connects an in-memory object with a remote instance of a DIG reasoner. The only mandatory parameter is the URL to address the reasoner.

Optionally the following fields are processed:

ua (default: LWP::UserAgent)

Here you can pass in your custom made HTTP client. Must subclass LWP::UserAgent.

kb

This method clones one knowledge base from the reasoner. You can have any number of these.
