Thread:Talk:Semantic Maps/Question about geocoding

I'm curious as to how geocoded addresses are stored and refreshed in Semantic MediaWiki. Let's say I have the below code in a page: }} When the geocoded address is stored into the Coordinates variable, when is it refreshed? I'm wondering, because if I have let's say 50,000 pages and it refreshes every night, then I'm going to hit Google's geocoding limit on a nightly basis. If it only geocodes when the page is saved, then I should be ok. Unless I run something to trigger an update of all the pages, then I'd have the problem again. Does any one know what is output when the geocoding limit is reached? Thanks
