Apple posts developer info for iTunes LP, Extras

Apple has posted a new page with links to information on how to build iTunes LP and iTunes Extra files for submission to iTunes. Linked on the new page are templates for creating the files, along with a how-to, best practices documents, a development guide, and information on asset delivery, testing, and TuneKit, Apple’s API for iTunes LP and Extras files. Interestingly, the first line of the TuneKit Programming Guide (PDF Link) references “Cocktail booklets,” which was the rumored codename for Apple’s new bundle format. The page notes that “[a]utomatic, electronic submission” of iTunes LP and Extras files is not scheduled to begin until the first quarter of 2010, and the process is currently manual and limited.
