About formats

DNG (Digital Negative) is an open, royalty-free RAW image format published by Adobe Systems on September 27, 2004, designed to address the proliferation of incompatible proprietary RAW formats from different camera manufacturers. Based on the TIFF/EP standard (ISO 12234-2), DNG provides a well-documented container for raw sensor data with standardized metadata tags that describe the camera's color filter array pattern, color calibration matrices, default rendering parameters, and opcodes for geometric corrections. The format supports both original raw mosaic data and linear (demosaiced) DNG, as well as lossy DNG using JPEG compression for smaller archive sizes when full quality is not critical. Adobe has iterated the specification through multiple versions, adding support for transparency maps, floating-point HDR data, enhanced color profiles, and semantic masks in newer revisions. One advantage is archival reliability — DNG's published, non-proprietary specification eliminates the risk that a camera manufacturer's format becomes unreadable when that company exits the market or drops support for older models, a concern that motivated Adobe's creation of the format. The format also enables embedded original RAW data, letting users convert their CR2, NEF, or ARW files to DNG while optionally keeping the original bits inside the DNG for reversibility. Broad ecosystem support is another strength: Adobe Lightroom, Photoshop, and Camera Raw treat DNG as a first-class format, and many smartphone manufacturers (including Google and Apple for certain modes) output DNG natively.

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.
