Blog post about "Provenance in RDF-star"

Dear all,

following a discussion during our two last calls, I published a post 
about "Provenance in RDF-star":

https://www.w3.org/community/rdf-dev/2022/01/26/provenance-in-rdf-star/


quoting the intro:

 > In this post, we present some lessons learned by the group through 
discussions and exchanges. This is meant to give some insight about the 
rationale behind RDF-star, and some guidelines about how to best use it 
for modeling provenance data.

Many thanks to all the participants of the RDF-star group for their 
reviews and feedback on this post.
