Apple File Formats · The whole world has been giving Microsoft a hard time over their Office XML file formats; it turns out that there are far worse sinners. Apple, for one. Derek Beatty here at Sun ran across this write-up on their iWork (Keynote, Pages, and so on) file formats, which are XML-based. Item: there’s no attempt to conform to OpenDocument or any other standard. Item: they change them at will: “With the introduction of Keynote 2.x, this schema file is out of date.” Item: They don’t exactly encourage using their specs to build software: “Although the information in this technical note may appear useful, you should not rely on it for developing or modifying your own products.” And, to cap it all: “This document does not describe the complete XML schema for either Pages 1.x or Keynote 2.x. The complete XML schema for both applications is not available and will not be made public.” [Emphasis Apple’s.] Charming stuff. [Update: Apple’s Ernie Prabhakar pushes back passionately.
