Abstract
This paper describes XMDF e-book data format and technologies, which have been developed by Sharp Corporation. The first e-book service based on XMDF started in 2001 and XMDF has expanded drastically in content genres and popularity ever since. It has also evolved to be a "content container" that packages contents of various formats not limited to XMDF for distribution.
The paper focuses on new features introduced with XMDF 3.0, its latest version. XMDF content production tools, which enable production of contents with a strong expression power at low costs, are also explained.
The authors are aiming to continue their contribution to the e-book industry with XMDF technologies, catering to diversifying needs in the market.
