About formats

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.

ODT (OpenDocument Text) is the word processing format defined by the OpenDocument Format (ODF) standard, developed by the OASIS technical committee and first published as ODF 1.0 on May 1, 2005, later adopted as international standard ISO/IEC 26300. An ODT file is a ZIP archive containing XML documents that describe text content, formatting styles, metadata, and settings using a vendor-neutral, royalty-free specification. The document body resides in content.xml with styling rules in styles.xml, while embedded images, fonts, and other resources are stored alongside in the package. The format supports rich word processing features including paragraph and character styles, tables, footnotes, tracked changes, table of contents generation, bibliography management, mail merge fields, and embedded vector and raster graphics. ODT serves as the native format for LibreOffice Writer, Apache OpenOffice Writer, and Calligra Words, and can be imported by Microsoft Word, Google Docs, and other commercial tools. One advantage is vendor independence — ODT is governed by an open standard rather than a single company, ensuring long-term document accessibility free from proprietary lock-in. This makes ODT particularly important for government agencies, educational institutions, and organizations with archival mandates. The XML-based architecture provides another strength, enabling programmatic document generation and processing using standard tools in any programming language.
