Hi Michel, FWIW most users who’ve ever expressed any interest wrt Turtle have been concerned more about how github and other diff tools work wrt Turtle files. That means a Turtle writer that, for example, that tries to remove inconsistencies in how the Turtle files are written to enable automated software development tools.
Anyway, hope that clarifies what the standard says is required and how Composer works. Cheers, David UK +44 7788 561308 US +1 336 283 0606 > On 12 Jul 2017, at 16:29, Bohms, H.M.
