Hi Pierre-Antoine,

RDF and RDF-Star are related, but different things.

As I see it, they are related by a desire to offer a syntax sugar that:

1. Negates the verbosity of Reification as defined in the RDF Vocabulary

2. Offers a compact syntax-sugar for expressing the properties of an RDF
sentence -- influenced by relationship labeling functionality offered
so-called Property Graph Databases

The reality, as I see it above, is difficult enough to explain
coherently in a forum comprising knowledgeable practitioners.

In my personal experience, I expect RDF and RDF-Star conflation (what
happens in the marketing realm) to ultimately reek havoc on RDF itself.

Remember, RDF already has a penchant for attracting confusion
(unfortunately!) while rarely receiving positive attribution for the
complex data-centric challenges that it handles both well and uniquely.

RDF-Star shouldn't be perceived (i.e. promoted) as an extension of RDF.
It is ultimately, a heuristic for handling a specific problem that has
little to do with RDF's actual data model.

A sentence is a sentence. You can't make a sentence do more than what it
was constructed to handle.

A document is where sentences live, it too has a special role in terms
of the context that it brings to bear re sentence interpretation.

*Simple example in plain English*

"Kingsley and Pierre-Antoine are RDF practitioners." is a sentence.
Temporal aspects of that sentence can be expressed in a variety of ways
without changing the fundamental nature and roles of sentences or the
documents within which they are created.

Modeling the sentence-example outlined above as a Graph doesn't change
the situation at hand.

RDF-Star, as I've always seen it, is simply trying to offer syntax-sugar
(via a heuristic) that's influenced by the perceived marketing-momentum
of a different genre of product that's based on a higher-level model
that's utterly inferior to RDF, as time will demonstrate.

BTW -- circa 2021, there is far more RDF on the Web
<https://twitter.com/search?q=%23SchemaOrg%20%23eCommerce%20%23RDF&src=typed_query&f=live>
than most assume. By that I mean, RDF as we all know it has already gone
past the point of critical mass and none of it includes or depends on
the issues RDF-Star is trying to address, IMHO.


*Conclusion*

RDF-Star and RDF are different things. Common model sharing is a
controversial perspective, IMHO.
