The document discusses how web technologies like XML, SVG, and SMIL can be used to make maps and geospatial information more accessible to people with disabilities. It explains that these technologies allow for content to be represented in multiple equivalent forms so that users can access information in the format that works best for them. The goal is to combine advances in interactive maps and geospatial data with accessibility principles to provide alternatives for people who have visual, mobility, or cognitive impairments. Standardizing metadata for geospatial objects would help ensure equivalent alternative representations can be discovered and transformed to meet different accessibility needs.
