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
JP2 (JPEG 2000 Part 1) is an image format based on the JPEG 2000 compression standard, developed by the Joint Photographic Experts Group and published as ISO/IEC 15444-1 in December 2000 as the successor to the original JPEG standard. Unlike JPEG's block-based discrete cosine transform, JPEG 2000 uses discrete wavelet transform (DWT) compression, which eliminates the characteristic 8x8 block artifacts visible in highly compressed JPEG images and instead produces a smooth, gradual quality degradation. The format supports both lossy and lossless compression within the same codestream, along with features absent from original JPEG: 16-bit and higher bit-depth images, arbitrary numbers of color channels, alpha transparency, region-of-interest coding (allocating more bits to important areas), and progressive quality or resolution refinement from a single compressed stream. One advantage is superior image quality at low bit rates — JPEG 2000 produces visibly cleaner images than JPEG at equivalent file sizes, particularly below 0.5 bits per pixel where JPEG exhibits severe blocking. The progressive decoding capability is another strength: a single JP2 file can be decoded at any resolution or quality level without encoding multiple versions, valuable for remote sensing and medical imaging where the same image must serve both thumbnail browsing and full-resolution analysis. JP2 is the mandated format for digital cinema (DCI), the preferred format in geospatial data (GeoJP2), and widely adopted in cultural heritage digitization.
