About formats

CGM (Computer Graphics Metafile) is a vector graphics standard defined by ISO 8632, first published in 1987 and developed through the ISO/IEC JTC 1/SC 24 committee. The standard defines a device-independent format for storing and transferring two-dimensional vector graphics, raster images, and text. CGM supports three encoding methods: character encoding (compact text representation), binary encoding (efficient machine-readable form), and clear-text encoding (human-readable for debugging). The format describes graphical primitives including polylines, polygons, ellipses, circular arcs, splines, and text with associated attributes for color, line style, fill patterns, and clipping boundaries. CGM found its strongest adoption in technical documentation, particularly in aerospace, defense, and industrial sectors where long-term archival and precise technical illustration are critical. One advantage is formal standardization — as an ISO standard, CGM provides vendor-neutral, specification-driven interoperability guaranteed across compliant implementations. The format's adoption in specialized industries is another practical strength: WebCGM, a W3C profile of CGM, became the mandated illustration format for interactive electronic technical manuals in the aerospace industry (ATA iSpec 2200), ensuring CGM's continued relevance in aviation maintenance documentation. While general-purpose vector work has moved to SVG and PDF, CGM persists in regulated industries where certified, standards-based graphics interchange is mandatory.

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.
