I wanted to enhance the app, We Love Apps, with the ability to follow updates and price changes on applications that are saved. I created a new Restful API on this site to track changes to applications. One of the awesome features of iTunes is that, developers that are affiliates with iTunes, you can download flat files of all iTunes data and as long as you follow their terms of service, display price changes and updates with apps.
One thing that Apple provides is a python script to do this importing to a mysql database for you. What I’ve done, since my shared host doesn’t support python, is to create a PHP version that can do all the leg work for you. Download their bzipped files, extract them and import them into a database. This can be easily added to a cron job on your host to do imports on a daily basis.
I’ll be fleshing it out over the coming days but a link to the repository is below. I’m still in the process of getting everything together to collect and put on the repository as well as some documentation. If you’re interested, check it out below.
