This PR has been addressing the changes in the PROJECT file which has been discussed for a while and that we reach a consensus. Also, I have been adding this PR for all week in the Slack channel to see if someone has some objection. It has 3 oks already then, it shows good enough to get merged:

/lgtm

PS.:See that the PR #1869 adds the same fields and also was approved by @estroz as well in the past. The reason for the old pr not get merged was the discussions regards the model changes which now are addressed properly via the PR; #1911.
