HTMLBook is an open, XHTML5-based standard for the authoring and production of both print and digital books. HTMLBook is built on the following premises: * Books are timeless. The basic "book" structure has persisted for hundreds of years and will continue to persist for our lifetimes, be it in digital or print form. * HTML is the markup language of the world for the foreseeable future. * Single-source document processing will remain valuable for the foreseeable future. As such, HTMLBook can be characterized in the following ways: * HTMLBook is a subset of XHTML5. All HTMLBook is XHTML5, but not all XHTML5 is HTMLBook. * HTMLBook contains no additional elements or attributes outside of the XHTML5 specification. * HTMLBook is semantically tailored to the structure of a book, including more complex content used in technical and reference documents. * HTMLBook is defined with and can be validated against an XML schema. * HTMLBook stylesheets are written in CSS. === Getting Started with HTMLBook Read the Working Draft of the HTMLBook Specification here: http://oreillymedia.github.io/HTMLBook/ Get the HTMLBook schema here: https://github.com/oreillymedia/HTMLBook/tree/master/schema The main HTMLBook Schema file is +htmlbook.xsd+, which imports Schemas (via W3C) for MathML and SVG validation. You can validate HTML documents against +htmlbook.xsd+ on the command line using +xmllint+: ---- $ xmllint --noout --schema htmlbook.xsd .html ---- Alternatively, to validate in a GUI XML editor like oXygen, add a +xsi:schemaLocation+ declaration to the root ++ element as follows: ---- ---- === Notes on HTMLBook * The HTMLBook specification is currently in Working Draft status, and will continue to be developed and revised for the foreseeable future. * If you have any bugs or feature requests for HTMLBook, please submit them via the Issues tab in GitHub. * In the coming months, we will be adding additional tools to the HTMLBook project for authoring and producing books with HTMLBook: CSS stylesheets, scripts for generating EPUB/Mobi, etc. * If you would like to contribute to the HTMLBook project, send us a pull request!
