Thread:Support/About MediaWiki:Mapsources-desc/cy/reply (4)

My involvement was mostly technical; most of the documentation was just copied.

I'm pretty sure it's the latter, though. "data sources" + "map sources". I believe the "data sources", in this context, refers to the left hand side data on e.g. https://en.wikivoyage.org/w/index.php?title=Special%3AMapSources&params=52%2C13%2Cscale%3D50000
