This is a formal message from RDF-WG to SPARQL-WG.
The RDF-WG is considering changing Turtle to include ":" as a legal
character in the local part of a prefixed name. They are asking whether
SPARQL-WG is open to making this as a co-ordinated change.
The effect is to make
music:album:track
a legal prefix name being the URI:
<http://ogp.me/ns/music#album:track>
RDFa allows RDFa-CURIES with ":" in the local part. [1]
See [2] for more examples.
This would break existing Turtle/SPARQL where no white space is used to
separate adjacent prefixed names.
For example, this is legal Turtle currently
------------------
@prefix a: <http://example/NS/> .
@prefix : <http://example/NS/> .
a:b:c:d .
------------------
meaning:
------------------
a:b :c :d .
------------------
because the : of :c ends the local part of a:b

not the CURIE note http://www.w3.org/TR/curie
which does not permit "a:b:c"
