Open textbooks is an initiative to make a free and opensource standard for textbook file publication and distribution.
The initiative will utilize Git repositories for XML encoded textbook files. Textbooks should be media rich (not your typical pdf style book), standardized format, and easily sharable. Furthermore, textbooks should be easily converted to html, Android and iPhone apps, and other formats.
Please checkout our git repository and feel free to give us pull requests with your features. A project roadmap will be published soon.
