I just made a change to the Turtle - Terse RDF Triple Language to fix an incompatibility with Notation3 after I did some testing against cwm (I also see reference to Turtle and other n3-like syntaxes in that page). The collection syntax uses a list of items with no commas allowed, whereas I had re-used the
objectList grammar term, which requires them. I've corrected the grammar by adding a new
itemList term and updating Raptor to match including a negative test case to check it.
Turtle seems to be getting some traction, at least I've had encouraging private feedback. I noticed that it was mentioned by Jim Hendler as a possible piece of work for the new Semantic Web Best Practices and Deployment Working Group and it was something I was thinking about - when to stabilise it and where.
