One time wikipedia editor (along with thousands of others). Concentrated on the metal working section and then left it when time and life got in the way.
I'm not a coder but can generally find my way around the simpler stuff.
I'm familiar with python2, or at least enough to turn out some workable code for weewx. Python3 and Gramps might be a bridge too far though.
The wiki; I might be able to do something there/here...
