About formats

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.
Initial release: 1991
HEIC (High Efficiency Image Container) is Apple's branded implementation of the HEIF (High Efficiency Image File Format) standard that uses HEVC (H.265) as its image compression codec. Apple adopted HEIC as the default photo format on iPhones and iPads starting with iOS 11 in September 2017, replacing JPEG for newly captured images. HEIC files store photographs compressed with the intra-frame coding mode of the HEVC video codec, which applies sophisticated prediction, transform, and entropy coding techniques that achieve roughly 50% better compression than JPEG at equivalent visual quality. The ISOBMFF (ISO Base Media File Format) container supports multiple images in a single file, enabling Live Photos (a still plus a short video clip), burst sequences, depth maps from dual-camera systems, and HDR gain maps that allow compatible displays to render extended dynamic range. HEIC also stores alpha channels, auxiliary images for computational photography features (portrait mode depth data, semantic segmentation masks), and comprehensive EXIF/XMP metadata. One advantage is storage efficiency: iPhones shooting HEIC use roughly half the storage of equivalent JPEG captures with no visible quality loss, a significant benefit on devices where storage is finite and photos accumulate rapidly. The format's integration with Apple's ecosystem is another key strength — HEIC files are natively supported across macOS, iOS, iPadOS, and iCloud Photos, and automatic JPEG transcoding during file sharing ensures compatibility when sending photos to non-Apple devices. HEIC can also be opened by Windows 10/11 (with codec), GIMP, ImageMagick, and Adobe Lightroom.
