About formats

ABW is the native document format of AbiWord, a free and open-source word processor originally developed by AbiSource in 1998 and later maintained as part of the GNOME Office suite. The format stores document content as well-formed XML, describing paragraphs, character formatting, page layout, headers and footers, tables, lists, footnotes, and embedded images in a human-readable structure. ABW files use a straightforward markup where document sections map to XML elements with attribute-based styling, making the format transparent and easy to parse programmatically. AbiWord was designed as a lightweight alternative to heavyweight office suites, running efficiently on older hardware and resource-constrained systems while still providing core word processing functionality. One advantage is the clean XML foundation — ABW files can be inspected, transformed, and generated using standard XML tools and scripting languages without requiring the AbiWord application itself. The lightweight nature of both the format and its parent application is another practical strength: AbiWord and its ABW format are commonly found on Linux distributions targeting older computers and educational deployments in developing countries through projects like OLPC. ABW files can be converted to mainstream formats like DOC, ODT, and PDF through AbiWord's built-in export or through document conversion tools.

VIFF (Visualization Image File Format) is a scientific image format developed by Khoral Research (originally at the University of New Mexico), first appearing around 1990 with the Khoros visual programming environment for image processing and data visualization. VIFF files use a 1024-byte header followed by optional color map data, and the image data itself, with the header containing detailed specifications: data storage type (bit, byte, short, integer, float, double, complex), data encoding (none, CCITT Group 3/4), color space model (none, generic, RGB, HSI, CMYK, and others), and support for multi-band (multi-channel) images with arbitrary numbers of bands. The format accommodates one-dimensional signals, two-dimensional images, three-dimensional volumes, and location data (sparse pixel coordinates), making it versatile beyond simple image storage. VIFF was designed for the Khoros/VisiQuest visual dataflow programming environment, where users constructed image processing pipelines by connecting processing nodes in a graphical canvas — an approach that influenced later systems like AVS, MATLAB Simulink, and LabVIEW. One advantage is scientific data fidelity: VIFF supports the full range of numeric types used in scientific computing (including complex numbers and double-precision floats), stores multi-band datasets natively, and carries calibration metadata — making it suitable for remote sensing, medical imaging, and spectral analysis applications where generic image formats lose information. The format's connection to the Khoros visual programming paradigm provides another notable dimension — VIFF was the standard I/O format for one of the most influential early visual programming environments for scientific image analysis. VIFF files can be read by ImageMagick and legacy Khoros/VisiQuest installations.
