Isn't the name "Data Application Programming Interface" redundant ? And "Hypermedia Application Programming Interface" wrong, because generally not for an application at all, but rather a (non-programming, as the author says, "for humans") interface to display multimedia documents ? (I guess you get (inevitable, if not necessarily good) feature creep as soon as you start including something like forms - see also : forms in pdfs ?)
