Yes, the baseURI should be a URI - "null" isn't legal syntax. The
base URI is the unique identifier for the file and is required. Check
the file for a triple that looks like:
<some-uri>
rdf:type <http://www.w3.org/2002/07/owl#Ontology> ;
This is a statement that "some-uri" is an ontology, where "some-uri"
will have a URI form (http://xyz.com...). Place that URI in the base
URI and you will at least have a valid URI for the file. However, the
source of the n3 file may have other issues with n3 (turtle) format
and should consult the W3C recommendations on n3/turtle syntax.
