Abstract:

The usage of SVG creates new possibilities as well as new challenges for the accessibility of Web sites. This paper presents a metadata vocabulary to describe the information content of an SVG file geared towards accessibility. When used with a suitable tool, this metadata description can help in generating a textual ('linear') version of the content, which can be used for users with disabilities or with non-visual devices.
