About formats

SXW is the word processing document format used by StarOffice 6.0 and OpenOffice.org 1.0, developed by Sun Microsystems and released in 2002. The format was one of the first mainstream office document formats to adopt an XML-based architecture, packaging document content, styles, metadata, and embedded media in a ZIP archive — a structural approach that directly influenced the later OpenDocument Format (ODF). The content.xml file describes the document body using XML elements for paragraphs, headings, lists, tables, footnotes, and inline formatting, while styles.xml defines the styling rules and meta.xml carries document properties. SXW represented a significant milestone in open-source office software, demonstrating that a non-proprietary XML format could handle the full range of word processing features including change tracking, indexes, cross-references, and complex page layouts. One advantage was transparency and openness — the XML structure made document content inspectable, transformable, and processable using standard tools, a sharp contrast to the opaque binary formats dominant at the time. The format's role as a technological precursor to the ODF standard is another historical significance: the OASIS OpenDocument Technical Committee used the OpenOffice.org XML format (including SXW) as the starting point for developing ODF 1.0. While SXW was superseded by ODT with OpenOffice.org 2.0 in 2005, existing SXW documents can be opened by LibreOffice, Apache OpenOffice, and document conversion tools.

MOBI is an ebook format originally developed by Mobipocket SA, a French company founded in 2000 that was later acquired by Amazon in 2005. The format builds on the PalmDOC/PDB container structure, adding support for HTML-based content markup, embedded images, a DRM layer, and a JavaScript subset for limited interactivity. MOBI files use a record-based database architecture inherited from Palm OS, with a header structure containing metadata like title, author, publisher, and language followed by compressed HTML content records. The format became the foundation of Amazon's early Kindle ecosystem — the original AZW format used on first-generation Kindles was essentially MOBI with Amazon's own DRM wrapper. MOBI supports reflowable text with basic formatting including bold, italic, headings, lists, and tables, as well as internal hyperlinks and a built-in table of contents. One advantage is broad device compatibility: MOBI files are recognized by Kindle devices and apps spanning over a decade of hardware, as well as numerous third-party readers on desktop and mobile platforms. The format's lightweight structure is another strength — even long novels produce compact files that load quickly on modest hardware. While Amazon has since moved to the more capable AZW3/KF8 format for new publishing, MOBI remains widely circulated in existing ebook libraries and continues to be produced by conversion tools like Calibre for maximum Kindle compatibility.
