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 Andy "the messenger" [1] http://www.w3.org/TR/rdfa-core/#s_curies not the CURIE note http://www.w3.org/TR/curie which does not permit "a:b:c" [2] http://ogp.me/Received on Wednesday, 28 March 2012 20:15:51 UTC
