Please rewind to your exchange with Reuben, hence my comments. Turtle is 
a notation (or so called concrete syntax), like JSON-LD, both enable 
structured data representation using the RDF model (which includes it 
relation semantics). The problem is that said "relation semantics" have 
to be discernible (readable) and comprehensible (understandable re. 
entailments) to both humans an machines. Thus, if you continue to insist 
on JSON-LD only, or question the virtues of Turtle, you end up with 
RDF/XML circa. 2013 where humans can't actually discern or comprehend 
the intricacies of the relation semantics expressed in the 
vocabulary/ontology.

Remember, the flawed justification for RDF/XML was that is was for 
machines. Basically, that it was for coders that wrote programs that 
machines understood. It cost this entire Semantic Web project 15 lost 
years. Even today, as already expressed, Turtle and JSON-LD aren't 
official standards, so it remains quite easy to ridicule the "Semantic 
Web" phrase when RDF/XML remains the official standard i.e., default 
used in all examples re. OWL and RDF Schema etc..


Many of us have been there and done that, many times over, during the 
last 15 years re. RDF. We don't want to ever go back to the mess created 
by RDF/XML, never ever.

If you are using RDF then there shouldn't be any debating it virtues, 
especially when it is already being used to drive the semantics 
expressed by the Hydra vocabulary/ontology.

Okay, but as I said, its secondary for now. When we come to this bridge, 
I am sure we can get over any concerns with ease and good examples etc.. 
You are knowledgeable enough about these matters for this to be a simple 
affair :-)
