Hi,
I'm working on a Wikipedia reader for the Apple iPod. To minimize the data size occupied on the iPod I will only store the current articles on the device (no "old"-table). However, the GFDL requires to mention the authors of an article. Thus, each article on the iPod should contain a list of all Wikipedia-users that appear in the revision history.
So, finally, my question is: Is there a way to get a list of the authors of each article without having to download the (extremely large) xmldump of all wikipedia-articles ever written since the beginning of time? I've already tried the online SQL querying mechanism, but it seems to limit queries to 1000 results and to not support queries on the "old"-table.
By the way, another question comes to my mind: If a contributor to an article wasn't logged in, do I have to mention his IP-number in the list of authors? I don't think this would make much sense, but perhaps it's legally required by the GFDL. Or is it sufficient to make the reader application display the string "There might be other (anonymous) contributors to this article"?
I'm looking forward to your replies, Robert
