Hello,

I've seen a few Javascript developers (including myself) go through this process:

* write a cool Javascript Freebase app (like Zak's
http://dev.mqlx.com/~zak/arch/) * decide to give users the ability to edit data * decide you can't be bothered to re-implement the features of the Freebase.com client (and learn mqlwrite + setup an api proxy) * Take the path of least resistance and use a modal dialog IFRAME to display the topic in Freebase

This Freebase-in-IFRAME approach has two problems:

* How do we know if the user changed data? (We want to avoid rebuilding the state of a complex AJAX app if possible) The mwLastWriteTime cookie may have been updated, but it's inaccessible since the app isn't on freebase.com

* How do we get this changed data? Since the mwLastWriteTime cookie isn't set, re-running the MQL query won't give the latest data. You need to resort to cache-busting techniques like incrementing limit'

Any ideas about how to solve these problems? cheers, --Will
