About formats

PDF (Portable Document Format) was developed by Adobe Systems, co-founded by John Warnock and Charles Geschke, with the first version released on June 15, 1993. Built on a simplified PostScript imaging model, PDF encapsulates complete document descriptions — text with fonts, vector graphics, raster images, and interactive elements — in a self-contained file that renders identically across every platform, device, and printer. The format evolved through multiple versions, culminating in its adoption as international standard ISO 32000-1 in 2008 (PDF 1.7) and ISO 32000-2 in 2017 (PDF 2.0), ensuring long-term vendor independence. PDF supports an extraordinary range of capabilities: digital signatures, form fields, annotations, bookmarks, accessibility tags, encryption, JavaScript, multimedia embedding, 3D content, and archival-specific profiles (PDF/A). One advantage is absolute visual fidelity — a PDF document looks exactly the same whether opened on Windows, macOS, Linux, iOS, or Android, printed on any printer, or viewed decades after creation. Universal software support is another core strength: PDF viewers are built into every major operating system and web browser, and the format is read by hundreds of applications worldwide. Specialized ISO profiles like PDF/A (archival), PDF/X (print production), and PDF/UA (accessibility) extend the format's reach into regulated industries. PDF has become the global standard for document exchange in business, government, legal, academic, and publishing contexts.

Initial release: June 15, 1993
DBK is a file extension associated with DocBook, a semantic markup language for technical documentation defined in XML (and originally SGML). DocBook was created around 1991 by HaL Computer Systems and O'Reilly & Associates, later maintained by the OASIS DocBook Technical Committee. The vocabulary provides over 400 element types designed specifically for books, articles, reference pages, and technical manuals — including structural elements (book, chapter, section, appendix), block elements (para, programlisting, table, figure), and inline elements (emphasis, filename, command, classname). Authors write content focusing on meaning rather than appearance, and separate stylesheets transform the DocBook source into output formats like HTML, PDF, EPUB, and man pages. One advantage is strict separation of content and presentation — a single DocBook source document can generate a printed book, a website, an ebook, and Unix man pages through different transformation pipelines, without any content duplication. The rich semantic vocabulary is another strength: because elements like <command>, <filename>, and <errorcode> carry precise meaning, toolchains can index, cross-reference, and validate technical content in ways that generic markup cannot. DocBook has been adopted by major open-source projects including the Linux kernel documentation, GNOME, KDE, and FreeBSD for their official documentation, and it remains the standard for single-source technical publishing.
