Dear Martynas,

first of all, this first published draft is just that: a draft. It 
represents the current state of the discussions, not a definitive consensus.

The main difference between the semantics proposed in the published 
draft, and the one from that email is this:

* the specs relies on RDF-star's abstract syntax, mapping it to (plain) 
RDF's abstract syntax to define it's semantics

* the email bypasses RDF-star's abstract syntax, mapping directly from 
Turtle-star to (plain) RDF's abstract syntax

During our last call [2], some of us (me included) have expressed 
concerns about bypassing RDF-star's abstract syntax. It is a useful 
abstraction of the different concrete syntaxes (defined in our draft or 
elsewhere, as e.g. JSON-LD-star), and in particular for SPARQL-star. 
Getting rid of the abstract syntax would need a complete rewrite of 
SPARQL-star's query semantics...
