Load meta-data on RDF repositories from FileOrDirectory. If 
the argument is a directory, this directory is processed recursively and 
each for each directory, a file named void.ttl,
Manifest.ttl or Manifest.rdf is loaded (in 
this order of preference).
Declared namespaces are added to the rdf-db namespace list. 
Encountered ontologies are added to a private database of
rdf_list_library.pl. Each ontology is given an
identifier, derived from the basename of the URL without the 
extension. This, using the declaration below, the identifier of the 
declared ontology is wn-basic.
