Developers familiar with other web standards can benefit from their existing knowledge. Being based on XML, SVG integrates well with modern development tools and common workflows. It also integrates with other W3C and OGC technologies, such as XML, DOM, Scripting, CSS, JPEG, PNG, SMIL, WMS, GML and others. The language independent DOM interfaces allow deleting, creating, changing or reordering elements in the document tree. The most common scripting language used with SVG documents is ECMAScript, also known as Javascript. SVG also supports multi-language documents, font-embedding and internationalization features. The XML namespace support enables the embedding of domain semantics and the extension towards domain specific applications. Network interfaces enable server client communication.
Synonyms SVG; Vector graphics for the Web; XML based vector graphics; Document object model; Web graphics standard; Rich client internet applications; SMIL; Open standard Definition SVG is a royalty-free and vendor-neutral two-dimensional web graphics standard developed by the W3C consortium. The XML based markup language describes and integrates vector graphics, raster graphics, text, multimedia, interactivity, scripting and animation. The SVG document consists of a tree-like structure, which can be interpreted by humans and machines. Graphical objects can be grouped, styled, transformed and composited into previously rendered objects. The feature set includes nested transformations, clipping paths, alpha masks, filter effects, template objects and extensibility. As the name indicates, SVG graphics can be scaled while maintaining quality. SVG graphics and applications can be viewed with most modern web browsers natively or by installing a plugin. The SVG standard can be used as a graphics exchange format, as a basis to build interactive and animated applications, web maps and online GIS.
Historical Background SVG 1.0 was developed by the W3C consortium, the organization responsible for the development of web standards. It became a W3C recommendation in 2001. Many wellknown corporations and research institutions contributed to the development of the SVG standard. Version 1.1 was released in 2003 and introduced different modules: SVG 1.1 Full, a module for desktop computers and two SVG mobile profiles: SVG Basic for PDA like devices and Smartphones and SVG Tiny for constrained mobile phones. In parallel, a SVG print module is developed as an XML based alternative to other printing languages, such as Postscript or PDF. It is not yet a W3C recommendation, but SVG is already a widely accepted graphics format in the XSL-FO document generation and printing industry. After the release of SVG 1.1, the W3C SVG working group started work on SVG 1.2. SVG 1.2 Tiny adds, among many other improvements, multimedia support
