About formats

DOTM is a macro-enabled template format for Microsoft Word, introduced with Office 2007 as part of the Office Open XML family. DOTM combines the template functionality of DOTX — providing reusable styles, page layouts, boilerplate content, and formatting definitions — with the ability to embed VBA macro code that executes in documents created from the template. The format is a ZIP archive containing XML parts for styles, document defaults, and theme definitions, plus a vbaProject.bin stream for the VBA project. This combination enables organizations to distribute not just visual consistency but also functional automation: every document created from a DOTM template inherits both the formatting framework and programmatic capabilities. Common use cases include templates that auto-populate document fields from corporate directories, enforce naming conventions, generate tables of contents, insert dynamic headers with project metadata, or validate document structure before submission. One advantage is embedded workflow automation — a DOTM template can include initialization macros that configure the document environment, register custom ribbon commands, and connect to data sources the moment a new document is created from it. The distinct .dotm extension allows administrators to apply differentiated trust policies for macro-containing templates versus standard DOTX files. DOTM is supported exclusively in Microsoft Word desktop editions where VBA execution is available.

LRF is the file format associated with Sony's BBeB (Broadband eBook) specification, jointly developed by Sony and Canon and introduced in 2004 with the Sony Librie EBR-1000EP — the world's first commercial E Ink e-reader. The format supports both reflowable text and fixed-layout page rendering, embedding fonts, images, vector graphics, and metadata within a compact binary container. LRF files use a block-based internal structure with object trees describing page layouts, text streams, image resources, and table of contents navigation. Sony's Reader devices and the companion desktop software (Sony Reader Library) served as the primary ecosystem for LRF content throughout the mid-2000s. A key advantage was its early adoption of high-quality font embedding and text rendering optimized specifically for E Ink displays, delivering a reading experience noticeably superior to many competing formats of the era. The format also supported bookmark synchronization, dictionary lookups, and annotations within the Sony Reader ecosystem. However, Sony officially discontinued BBeB/LRF support in 2010, migrating its Reader platform to the industry-standard EPUB format. Today LRF files are primarily encountered in personal ebook collections from that period and can be converted to modern formats using tools like Calibre. The format remains a historically significant milestone as the native format of the device category that launched the modern e-reader revolution.
