ABSTRACT:
A method for controlling the release of an as-rendered configuration of a digital work, comprising the steps of presenting said digital work as a composite of a plurality of layers comprising at least a first layer and a second layer; providing a rendering protocol interface which is adapted for defining said as-rendered configuration of the digital work by specifying a first rendering status of said first layer and a second rendering status of said second layer; providing a rendering protocol facility adapted for storing and controlling the release of said first and second rendering status of said first and second layers respectively in accordance with said as-rendered configuration; restricting unauthorized access to the rendering protocol interface, thereby preventing unauthorized modification of said as-rendered configuration; and releasing said digital work with said as-rendered configuration. The method has application in selling books, movies, software, music and other information products. A method of selling a preview version of an information product along with an option of purchase of the original version is described.
