In my learning how to program Freebase, I've come across links to the Wikipedia that make use of a curid parameter. For example,
http://en.wikipedia.org/wiki/index.html?curid=296716
is the same as
http://en.wikipedia.org/wiki/Daniel_Akaka
At least, the two pages seem to be the same thing as far as I can see.
How to do a lookup btween curid and the page title? One way is ff we're screen-scraping, the page source of http://en.wikipedia.org/wiki/Daniel_Akaka contains
var wgArticleId = "296716";
And if you go to http://en.wikipedia.org/wiki/index.html?curid=296716 lots of indication of what the title is, including the permanent link (e.g., http://en.wikipedia.org/w/index.php?title=Daniel_Akaka&oldid=278490360)
To dig deeper, I might want to understand the mediawiki data structure and the mediawiki API.
