Hi Nicolas, thanks for the summary.  You're preaching to the converted
here, I've been a turtle evangelist for about a decade.  I guess the only
challenge is the network effect around turtle is much smaller than around
JSON.

All of those points made sense to me, though one I struggled to fully
understand:

"Turtle is unambiguous, JSON is not. JSON-LD emerged as a standard to work
with the semantic web, but it currently has four different profiles, is
surprisingly difficult to write well for larger data structures, and as
often as not is rejected primarily because it fails to conform to any of
the profiles. Turtle has two profiles that have very clear syntax (Turtle
and Turtle-Star), with Turtle-star being only slightly less clear because
of a few edge cases that haven’t been fully resolved. Additionally, when
people refer to Turtle, they are usually actually talking about TRIG, which
extends the turtle language to incorporate named graphs (TRIG is backwards
compatible with Turtle)."

The word that interests me here is "unambiguous", partly because we are
currently trying to (re)define WebID in the CG as an HTTP URI that
"unambiguously" denotes an agent.

The term unambiguous comes up a lot in sem web discussions, and I'm not
really sure I've fully grasped its meaning and how it differs from
uniqueness and universality.
