Designing a preliminary E-textbook with the information model

Recently, ISO/JTC1 SC36 has initiated a new standard project on e-Textbook, which was proposed by the authors' team. In this project, the information model of e-Textbook is the most fundamental part and further studies all will be based on it. The purpose of this paper is to manifest the information model of the e-Textbook by describing a practical case in our ongoing work. The process of designing an English e-Textbook for grade 6 is presented to explain the main steps of element structure design and function structure design. The information model and its practice reflect what kind of e-Textbook we need and how to design a standard e-Textbook for discussing the disorder of e-Textbook's development.
