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.

RB is the native ebook format of the Rocket eBook, one of the first commercially available dedicated e-reading devices, developed by NuvoMedia and released in October 1998. Founded by Martin Eberhard and Marc Tarpenning — who later co-founded Tesla Motors — NuvoMedia designed the Rocket eBook as a handheld device with a reflective LCD screen, capable of storing approximately ten books in its internal memory. The RB format packages HTML-based content along with embedded images, metadata, and a table of contents into a single binary container optimized for the device's limited hardware. Content was purchased and downloaded through NuvoMedia's RocketLibrarian desktop software. A notable advantage of the format was its early support for bookmarking, annotation, dictionary lookups, and adjustable font sizing — features now standard on modern e-readers but revolutionary in the late 1990s. The Rocket eBook demonstrated viable commercial demand for dedicated reading devices, paving the way for subsequent platforms from Sony, Amazon, and others. NuvoMedia was acquired by Gemstar-TV Guide International in 2000, which discontinued the device line in 2003. While RB files are largely a historical curiosity today, they can be converted to modern formats using ebook management tools, and the format remains significant as a pioneering chapter in the evolution of digital reading.
