About formats

KWD is the native document format of KWord, the word processor component of KOffice (later renamed Calligra Suite), developed by the KDE community with its first stable release in KOffice 1.0 in 2000. KWord distinguished itself from other word processors through a frame-based layout model where text, images, and other content existed in independent frames that could be positioned freely on the page, similar to desktop publishing applications — a departure from the linear text-flow approach used by most word processors. KWD files store document content in a compressed XML format that describes the frame hierarchy, text content with formatting markup, paragraph styles, page dimensions, headers, footers, and embedded media. The format uses a ZIP container packaging the XML document alongside any referenced images and resources. One advantage was the flexible frame-based layout — users could position text and image frames independently on the page, enabling newsletter-style layouts and creative document designs without switching to a dedicated DTP application. The open XML structure is another benefit, making KWD files transparent and accessible to automated processing. KWord was included in several Linux distributions as part of the KDE desktop environment during the 2000s. The project was eventually discontinued in favor of Calligra Words, which adopted the ODF standard. KWD files can be opened with legacy KOffice installations or converted through document conversion tools.

FB2 (FictionBook) is an XML-based ebook format created by Dmitry Gribov in 2004, designed to provide a clean semantic description of a book's content independent of its visual presentation. Unlike page-layout formats, FB2 encodes structure — title, authors, chapters, annotations, genres, epigraphs, poems, footnotes, and binary attachments (typically cover images) — within a single well-formed XML document. This structural approach means reading applications have full control over rendering, allowing the same file to adapt perfectly to a small phone screen or a large e-ink reader. FB2 became enormously popular in Russia and Eastern Europe, serving as the dominant format on major Russian digital libraries and ebook distribution platforms. One significant advantage is metadata richness: the format's schema mandates detailed bibliographic information including author, translator, series position, publication date, and genre classification, making library management and discovery straightforward. The plain-text XML foundation is another strength — FB2 files are human-readable, easy to validate, and simple to transform using standard XML tools like XSLT. The format specification is freely available on GitHub, and a wide ecosystem of readers, editors, and converters supports it across all major platforms, from desktop applications like Calibre to dedicated e-readers with native FB2 rendering.
