Comments on the ntriples syntax

I have been editing a new version of the RDF test cases doc and
updated the N-Triples section.  With respect to the comments you
raise in
  http://lists.w3.org/Archives/Public/www-rdf-comments/2001JulSep/0288.html

You raised these points:

* Why not have a canonical N-Triples form and allow comparison using cmp

  As Art Barstow notes in 
    http://lists.w3.org/Archives/Public/www-rdf-comments/2001JulSep/0293.html
  this is actually a graph comparison problem between the two (or
  more) graphs created when the N-Triples files are processed into
  RDF graph models.

  Since each of these RDF graphs can be arbitrary, and there is no
  good way to provide a canonical ordering of arbitrary graphs, and
  even if there were, this format is meant to be easy for people to
  read and write, so we make the machines do a little more work
  instead.

  The syntax details such as comments don't really interfere but
  rather are useful for people to indicate the usual kind of stuff
  such as copyright, source code version information, reasons for the
  test, pointers to references etc.

  We have now had several implementations of this standard graph
  comparison algorithm for N-Triples and it seems relatively easy and
  straightforward for the small test cases that we are using.  We
  appreciate there are issues with doing this for larger graphs in
  which case more sophisticated algorithms may be needed.

* Strange escaping for URIs

  I have replaced this with the recommended %HH hexadecimal escaping


These changes have been folded into
  http://www.w3.org/2001/08/rdf-test/

  (the list of the changes is at the end of that doc)

I hope this is satisfactory to you.

Thanks

Dave
