Hi, I'm trying to understand how the following file is a valid NTriple file (which is found in the Turtle compliance tests): http://www.w3.org/TeamSubmission/turtle/tests/test-29.out The question is about the object in the triple starting with: "<scheme:\u0001" which, following NTriple escaping, a URI Reference "scheme:" followed by unicode character 0001. It seems like this is an invalid URI. It confused me because the manifest actually says "Escaping U+0001 toU+007F in a URI". It would seem that this example would be simpler to a be literal rather than a URI. The way to parse these files seems to be to perform NTriple escaping and then parse the string as a (absolute) URI. That's how I get an invalid URI so I must be doing something simple wrong. Maybe a solution is to have a special NTriple escaping for URIs (\u0001 -> %01)? Except of course, those that are "ALPHA (%41-%5A and %61-%7A), DIGIT (%30-%39), hyphen (%2D), period (%2E), underscore (%5F), or tilde (%7E)" (from the RFC on URIs). -Andrew
