I've got round to updating the Turtle parser (RIOT) for the changes for
the Last Call publication of the Turtle spec from the RDF-WG.
Editors working draft:
http://dvcs.w3.org/hg/rdf/raw-file/default/rdf-turtle/index.html#
The writers have not been updated.
The changes are all additional things except one item which is an
alteration.
Added:
1/ The local part of a prefixed names can have %xx
Now legal:
ns:foo%23bar
and this puts %-2-3 into the URI (it does not convert it to numeric
codepoint i.e. #)
2/ The local part of a prefixed names can have character escapes
'_' '~' '.' '-' '!' '$' '&' "'" '(' ')' '*' '+' ','
';' '=' '/' '?' '#' '@' '%'
Now legal:
ns:foo\#bar
3/ PREFIX and BASE (any case) are synonyms for @prefix and @base except
they don't take a DOT at the end of the declaration.
Change:
4/ XSD decimals now need a digital after the decimal point in their
short form. Previously, the character sequence 123. used to be an XSD
decimal; it is now an XSD integer and a DOT. As space-DOT is much, much
more common, the WG hopes this will not be a major issue. SPARQL 1.1
made the change and so far it has not been an issue there.
The RIOT turtle parser passes the current draft test suite [*], as does
Gregg Kellogg's mods for RDF.rb. (The test suite is work-in-progress in
RDF-WG and subject to change.)
Andy
[*] Poacher and gamekeeper (I wrote the tests) but I promise I wrote the
tests, *then* made the Turtle parser pass them. Honest.
