This project has produced a system that can be used to create and display slide-shows, like the sort produced by the other presentation software, using XML (Extensible Markup Language) as the storage language for the slide-show and SVG (Scalable Vector Graphics) as the display language. udXML is a meta-data ??? a language to create other language ??? developed by W3C (World Wide Web Consortium) for use across the Word Wide Web. It is a simple, very flexible text format derived from SGML (ISO 8879). Originally designed to meet the challenges of large-scale electronic publishing, XML is also playing an increasingly important role in the exchange of a wide variety of data on the Web and elsewhere.udSVG is a language for describing two-dimensional graphics and graphical applications in XML. The visual appearance of SVG graphics is stored as a text-based description and its display is recalculated when it is rendered. SVG is used for storage and distribution of images on the Web, and is increasingly well-supported by both commercial and free software. In contrast with raster image formats such as GIF, JPEG, and PNG, which store a matrix of individual pixels that compose an image, an SVG image is a graphic-based text. It contains instructions for resolution independent rendering: the same SVG file will be shown in more detail when viewed at a higher resolution.
