With InDesign it is possible to createaccessible body text content and simple image descriptions, and add semantictags, headings, and paragraph styles to produce clean, semantic EPUB files. However,to obtain a fully accessible EPUB, additional manual work on the exported fileis necessary, such as adding ARIA roles, cleaning up code for a table, andadding accessibility metadata (these items are discussed in this document).
Afootnote or endnote should be encased in an tag. This tellsassistive technology that this text is supplementary content. Next, anepub:type of footnote or endnote identifies them to the reading system, and anARIA role of doc-footnote or doc-endnote, identifies it to assistivetechnology. These three specifications allow your footnotes and endnotes to befound by the reader and displayed by the reading system, without everdisrupting the main narrative.
Youcan create a simple table with InDesign, but it will not automatically be fullyaccessible. Column headers, which are very important to accessibility, do notappear in the form of code necessary to be voiced by screen readers whenexported to EPUB. These must be added manually.
An important addition to EPUB 3.0 semantics is ARIAroles or Accessible Rich Internet Applications. Since the release of EPUBversion 3.0, ARIA Roles can be added to EPUB 3.0 files to make navigationeasier for assistive technologies such as screen readers. They add more contentand meaning, and can add useful navigation information that is not alwayspicked up or present in the HTML. Assistive technologies understand ARIA rolesbut do not always understand epub:type semantics.
Note: Unfortunately, not only is this procedure abit complicated, but the code it produces still needs work. It might just beeasier to add the epub:type semantics, along with the ARIA roles, to sectionspost-export.
EPUB is an e-book file format that uses the \".epub\" file extension. The term is short for electronic publication and is sometimes styled ePub. EPUB is supported by many e-readers, and compatible software is available for most smartphones, tablets, and computers. EPUB is a technical standard published by the International Digital Publishing Forum (IDPF). It became an official standard of the IDPF in September 2007, superseding the older Open eBook (OEB) standard.
The EPUB 3.0 specification became effective in October 2011, superseded by a minor maintenance update (3.0.1) in June 2014. New major features include support for precise layout or specialized formatting (Fixed Layout Documents), such as for comic books, and MathML support. The current version of EPUB is 3.2, effective May 8, 2019. The (text of) format specification underwent reorganization and clean-up; format supports remotely hosted resources and new font formats (WOFF 2.0 and SFNT) and uses more pure HTML and CSS.
Unicode is required, and content producers must use either UTF-8 or UTF-16 encoding. This is to support international and multilingual books. However, reading systems are not required to provide the fonts necessary to display every Unicode character, though they are required to display at least a placeholder for characters that cannot be displayed fully.
The mimetype file must be a text document in ASCII that contains the string application/epub+zip. It must also be uncompressed, unencrypted, and the first file in the ZIP archive. This file provides a more reliable way for applications to identify the mimetype of the file than just the .epub extension.
EPUB 3.2 was announced in 2018, and the final specification was released in 2019. A notable change is the removal of a specialized subset of CSS, enabling the use of non-epub-prefixed properties. The references to HTML and SVG standards are also updated to \"newest version available\", as opposed to a fixed version in time.
EPUB is widely used on software readers such as Google Play Books on Android and Apple Books on iOS and macOS and Amazon Kindle's e-readers, but not by associated apps for other platforms. iBooks also supports the proprietary iBook format, which is based on the EPUB format but depends upon code from the iBooks app to function.
The first file in the archive must be the mimetype file. It must be unencrypted and uncompressed so that non-ZIP utilities can read the mimetype. The mimetype file must be an ASCII file that contains the string \"application/epub+zip\". This file provides a more reliable way for applications to identify the mimetype of the file than just the .epub extension.
Robert Martin, also known as Uncle Bob, first published this classic book in 2008. In addition to being one of the authors of the Agile Manifesto, he pioneered several modern principles of clean coding, such as the SOLID design principles.

HTML source code, provided as a Python string, from which a so-called Document Object Model (DOM) is created. As usual, this string may be read from a file, be stored in a Python variable of the script, or be programmatically created by the script itself via an API (Xml).
CSS (Cascaded Style Sheet) source code, provided as a Python string. CSS can be used to provide styling information (text font size, color, etc.) like it would happen for web pages. Obviously, this string may also be read from a file.

How to Write Code You're Proud of . . . Every Single Day\". . . [A] timely and humble reminder of the ever-increasing complexity of our programmatic world and how we owe it to the legacy of humankind--and to ourselves--to practice ethical development. Take your time reading Clean Craftsmanship. . . . Keep this book on your go-to bookshelf. Let this book be your old friend--your Uncle Bob, your guide--as you make your way through this world with curiosity and courage.\"--From the Foreword by Stacia Heimgartner Viscardi, CST & Agile MentorIn Clean Craftsmanship, the legendary Robert C. Martin (\"Uncle Bob\") has written the principles that define the profession--and the craft--of software development. Uncle Bob brings together the disciplines, standards, and ethics you need to deliver robust, effective code and to be proud of all the software you write.Robert Martin, the best-selling author of Clean Code, provides a pragmatic, technical, and prescriptive guide to the foundational disciplines of software craftsmanship. He discusses standards, showing how the world's expectations of developers often differ from their own and helping you bring the two in sync. Bob concludes with the ethics of the programming profession, describing the fundamental promises all developers should make to their colleagues, their users, and, above all, themselves.With Uncle Bobs insights, all programmers and their managers can consistently deliver code that builds trust instead of undermining it--trust among users and throughout societies that depend on software for their survival.Moving towards the \"north star\" of true software craftsmanship: the state of knowing how to program wellPractical, specific guidance for applying five core disciplines: test-driven development, refactoring, simple design,collaborative programming, and acceptance testsHow developers and teams can promote productivity, quality, and courageThe true meaning of integrity and teamwork among programmers, and ten specific commitments every software professional should makeRegister your book for convenient access to the book's companion videos, updates, and/or corrections as they become available.

Built on source code used for Acrobat, our SDK is compatible with Adobe products and specifications. Developers can have confidence that files will be conformant, reduced development time, and fewer manual errors.
When using LaTeX, the following packages need to be available (they are included with all recent versions of TeX Live): amsfonts, amsmath, lm, unicode-math, iftex, listings (if the --listings option is used), fancyvrb, longtable, booktabs, graphicx (if the document contains images), hyperref, xcolor, soul, geometry (with the geometry variable set), setspace (with linestretch), and babel (with lang). If CJKmainfont is set, xeCJK is needed. The use of xelatex or lualatex as the PDF engine requires fontspec. lualatex uses selnolig. xelatex uses bidi (with the dir variable set). If the mathspec variable is set, xelatex will use mathspec instead of unicode-math. The upquote and microtype packages are used if available, and csquotes will be used for typography if the csquotes variable or metadata field is set to a true value. The natbib, biblatex, bibtex, and biber packages can optionally be used for citation rendering. The following packages will be used to improve output quality if present, but pandoc does not require them to be present: upquote (for straight quotes in verbatim environments), microtype (for better spacing adjustments), parskip (for better inter-paragraph spaces), xurl (for better line breaks in URLs), bookmark (for better PDF bookmarks), and footnotehyper or footnote (to allow footnotes in tables). 153554b96e
