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.

PDB (Palm Database) is a generic database container format created by Palm, Inc. for the Palm OS platform, first appearing with the original PalmPilot in March 1996. In the ebook context, PDB files most commonly use the PalmDOC or Plucker encoding to store readable text with basic formatting. The format consists of a 78-byte header identifying the database name, creation date, and record count, followed by a record index table and the data records themselves. PalmDOC-encoded PDB files use a simple LZ77-based compression scheme to pack plain text efficiently, while Plucker extends this with HTML rendering, image support, and hyperlink navigation. PDB ebooks powered a thriving mobile reading ecosystem years before dedicated e-readers existed — millions of Palm OS users carried entire libraries on devices like the Palm V, Tungsten, and Treo handhelds. A primary advantage is extreme simplicity: the flat record structure and minimal overhead mean PDB files parse instantly even on severely constrained hardware with limited memory and processing power. The open, well-documented structure is another strength, having spawned numerous reader applications across Palm OS, Windows, and later mobile platforms. Though the Palm platform is long discontinued, PDB ebooks remain accessible through conversion tools and readers like Calibre, and the format holds historical significance as one of the earliest practical mobile ebook solutions.
