Not really TBC questions but I guess you can give the best answer.

I see popularity of json-ld rising a lot (as optimal compromise between webdev 
and ld/sw world) where people might just forget about the (for them) complex 
RDF conceptuals above….

In that sense I see more and more projects that go json-ld (iso rdf/xml, turtle 
etc.) also involving storage options like mongodb iso triple/quad stores. At 
the same time people like graphql(-ld) over sparql.

These trends gives rise for me to some issues:

1.
If RDF* evolves bringing us better metadata options (treating statements as 
objects again) on LD side would that also give rise to a JSON-LD* next to 
Turtle*?
Or is json-ld already by itself more flexible here so that no change is needed? 
(ie is the current use of json-ld as RDF serialization an already restricted 
usage?)

I am trying to find out if turtle and hence Turtle* will have advantages over 
json-ld…

2.
I know graphQL-LD approach as defined/demonstrated etc. by Ghent university 
(https://comunica.github.io/Article-ISWC2018-Demo-GraphQlLD/).
Is your prefixes graphql schema extension doing (functionaly) the same?
If so isn’t there room for a standard graph-ql-ld variant having those 
extensions in a standard way?
Or… is such a GraphQL update already in the making (much a like json to 
json-ld)?

3.
What will happen in future: shacl or graphql schema or both?
(knowing slide no. 20 from: 
https://www.topquadrant.com/project/graphql_json_rdf/)

4.
Why is there a graphql schema language anyway? Why not use json-ld schema 
definitions for that (because it is not powerful enough)?
(like in schema.org if I am right)

Sorry if these questions are out of scope.
It’s just that I need some story when people ask “why do we have shacl/sparql, 
graphql schema/graphql, json-ld for schemas (and also json schema)….can’t you 
make up your mind?”😊

Thx for your views
