Map internationalization launched everywhere—and embedded maps now live on 276 Wikipedias

As of today, interactive (Kartographer) maps no longer display in the language of the territory mapped; instead, you’ll read them in the content language of the wiki where they appear—or in the language their authors specify (subject to availability of multilingual data). In addition, mapframe, the feature that automatically embeds dynamic maps right on a wiki page, is now live on most Wikipedias that lacked the feature. (Not included in the mapframe launch are nine Wikipedias that use the stricter version of Flagged Revisions).

If you you’re new to mapframe, this Kartographer help page shows how to get started putting dynamic maps on your pages.  If you’d like to read more about map internationalization: this Special Update explains the feature and its limitations; this post and this one describe the uses of the new parameter, lang=”xx”, which  lets you specify a map’s language. And here are some example maps, to illustrate the new capabilities.

These features could not have been created without the generous programming contributions and advice of map-loving volunteers, including Yurik, framawiki, Naveenpf, TheDJ, Milu92, Atsirlin, Evad37, Pigsonthewing, Mike Peel, eranroz, Gareth and Abbe98. My apologies to anyone I’ve missed.

The Collaboration team's Map Improvements 2018 project wraps up at the end of June, so please give internationalized maps and mapframe a try soon and give us your feedback on the project talk page. We’re listening. —JMatazzoni (WMF) (talk) 20:59, 9 May 2018 (UTC)
