Hi Pierre-Antoine,

An opening example in that blog post:

PREFIX : <http://www.example.org/>

<< :employee38 :jobTitle "Assistant Designer" >>
     :accordingTo :employee22, :employee38 ;
     :confidence 0.8 .

My variant using RDF as it exists.

## RDF-Turtle Start ##

# PREFIX : <http://www.example.org/>
PREFIX schema: <http://schema.org/>
PREFIX : <#>

[
   :jobTitle "Assistant Designer" ;
   schema:identifier :employee38  # if desired, 
inverse-functional-property semantics can be applied to the 
schema:identifier relation.
] :accordingTo :employee22, :employee38 ;
   :confidence 0.8 .

## RDF-Turtle End ##

What is the difference between both? Is it that your RDF-Star example 
expresses a statement (*utterance*) while mine expresses a fact 
(*proposition*)?

"A *statement* occurs at a particular time and place.  But a *fact* is 
independent of time and place." [1]
