Function details:

Yet another set of obsolete Billboard URLs. This time, it's the class that looks like http://www.billboard.com/bbcom/discography/index.jsp?JSESSIONID=irrelevantnoisestring&pid=147604&aid=413521. If you look at the context in MTV Unplugged (Shakira album), you can see that the original article expects to find chart positions for the album. Billboard doesn't arrange its articles exactly that way any more, but I can come close.

First key is the performer id (pid). In this case, I can build http://www.billboard.com/artist/dummy/147604 . Billboard will redirect the URL and 404 the result, because "dummy" isn't a good artist. Note that the failing redirect is to http://www.billboard.com/artist/278867/dummy, though. From that URL, I can extract 278867, and build http://www.billboard.com/node/278867. That page redirects to http://www.billboard.com/artist/278867/shakira, which gives me enough information to build a URL to the chart listing.

Using similar processing, I can salvage links like http://www.billboard.com/bbcom/bio/index.jsp?pid=23708, used in Ramsey Lewis. It becomes http://www.billboard.com/artist/dummy/23708 which becomes http://www.billboard.com/node/359857 which becomes http://www.billboard.com/artist/359857/ramsey-lewis .

This bot will look for links in these two forms and replace them with the modern forms. It's only a mild rework of Chartbot 3, as the redirect chasing logic needs a trivial extension. It will flag any artists that are not included in {{BillboardID}} and not perform the repair if that is the case. It will require a second run after {{BillboardID}} has been repaired to pick up any stragglers.

Trial complete. Just ran the 50 edits, from 26 mrt 2013 01:57 to 26 mrt 2013 02:30. Looking at edits like this one, you can see that the algorithm pulls out the correct article. I also found that the code worked well with the forms http://www.billboard.com/..../bio/pid and http://www.billboard.com/artist/name/pid, so I've added those patterns in. An example of one of those edits is here. There was one slip with specifying "bio=true" in the template when "chart=all" would have been more appropriate, but that's a trivial fix.—Kww(talk) 02:33, 26 March 2013 (UTC)[reply]
