Recently, I tried to add the tag iso-prolog. However, Charles, who describes himself as "a proud member of the New Tag Deletionist Cabal" removed this tag. We have tags prolog as such, as well as for each implementation, like swi-prolog, gnu-prolog. Questions related to the ISO standard of Prolog thus have no tag currently. For this reason, I tried to add it. Is there a way to do so?
Edit: Problem solved!
