Review in RPE
Accepted answer
You can derive URI for revisions data source for each artifact, but not for reviews.
Once you create a review and add artifacts, you can only use
https://server:port/rm/publish/reviews?resourceURI=<resourceURI>. where <resourceURI> is UUID of review.
So you can start with reviews and dataSource/artifact/aggregatedContent/reviewParticipants/reviewParticipant will give all artifacts that are participants in the review. You cannot have reviews data source URI for each artifact. If you try that, you will get Error 400.

review.dta is readily available in the machine where DNG is installed (under <JTS>\server\conf\rm\reporting\initialization\templates\rrdg). You can open it in RPE and modify it as per your requirements.
