Thread:Talk:Semantic Maps/tutorial on adding a map form input

Would anyone be willing to provide a step by step tutorial on how to add a semantic map form input (preferably through page schemas but not required). I don't want the form to create a new page, but I want it to be a field in an existing form where a user puts in the address, then the coordinates and map are calculated and inserted (into the body, infobox, whatever) of an existing page with an existing form.

Thanks,

Matt
