java - Reading URIs with spaces in Turtle using Jena? -


i'm trying read rdf turtle file (shown below), i'm having 2 problems. first, there problem whitespace in rdf or turtle? somtimes, have problem reading uris l ike <i/o performance>. problem disappears when remove spaces, giving <ioperformance>. in file below, have problem <standard(m1) - small(default)>. here code loading file , listing subject, predicate, , object of each triple.

  stmtiterator iter = model.liststatements();     while (iter.hasnext()) {         statement stmt = iter.nextstatement();         resource subject = stmt.getsubject(); // sujeito          property predicate = stmt.getpredicate(); // predicado          rdfnode object = stmt.getobject(); // objeto          system.out.println((subject.getlocalname());         system.out.println((predicate.getlocalname().tostring());           system.out.println(stringutils.substringbetween(object.tostring(),"", "^"));     }

<standard(m1) - small(default)> not legal uri.

  1. it has spaces in it.
  2. it's relative uri (relative file read from) makes hard guess full, absolute uri.

either add @base or use prefixed name.
