About formats

POTX (PowerPoint Template XML) is the Open XML template format for Microsoft PowerPoint, introduced with Office 2007. A POTX file is a ZIP archive containing XML parts that define slide masters, slide layouts, theme colors, theme fonts, theme effects, placeholder configurations, and default content — everything needed to establish a consistent visual foundation for new presentations. When applied, a POTX template creates a new PPTX document inheriting the template's complete design system, including multiple slide layout variants (title, content, two-column, comparison, blank, and custom layouts) each with precisely positioned placeholders. The XML-based structure brings advantages over the legacy POT format: templates can be inspected and modified using standard XML tools, design elements are cleanly separated into dedicated files (theme.xml, slideMaster.xml, slideLayout.xml), and built-in ZIP compression yields smaller file sizes. One advantage is design system management — POTX files encapsulate an entire visual identity as a distributable package, and the modular XML structure makes it straightforward to update individual elements like color schemes or font stacks without rebuilding the entire template. Broad compatibility is another strength: POTX templates work in PowerPoint on Windows and macOS, LibreOffice Impress, and online platforms. The format integrates with PowerPoint's template gallery and organizational template libraries, enabling centralized design governance across large teams.

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.
