Hello,
On a side of the extension discussion I asked myself a question: How should plain editors use the new maps?
I can imagine the following simple things that most people would probably want to do first:
1. just put a static map in the article 2. overlay the static map with some simple layer of images (like it's done with templates using CSS)
How should they do (1)? Our current extensions provide usually some tag with coordinates as parameters. Do you think it would be feasible that we could allow use of OSM URLs, so that the user can just go to OSM, pan and zoom as they wish, pick a permalink or shortlink and paste it into some MediaWiki tag?
Any thoughts on solving (2) better? I thinking about something simpler than what we have now (since we should be able to provide custom layers anyway at some point).
