Accessibility is about 'providing access to all' - whether the user is colour blind, from a different culture, a different country, or of a different technical ability.

We aim to make the HELM website accessible to the widest possible audiences and strongly believe in the use of recognised standards. The World Wide Web Consortium (W3C), in particular, produce and evolve an ever-increasing set of standards to sustain and improve the growth of technology that will achieve a high degree of usability for people with disabilities.

This site adheres to (or uses) the following (mainly W3C) recognised standards:

• Extensible mark-up language (XML)
• Extensible Stylesheet Language Transformations (XSLT)
• Extensible HyperText Markup Language (XHTML)
• Cascading Style Sheets (CSS)
• Resource Description Framework (RDF)
• Web Accessibility Initiative (WAI)
• Dublin Core Metadata

Through the use of these standards, we are creating a site that:

• is faster, more useful, and more accessible for our visitors.
• is easier to maintain for our site editors.
• produces easily digestible/understandable code for external web agents (e.g. search engine spiders).

The HELM website is driven by the Amaxus Content Management System, which includes built-in functionality to achieve the highest possible accessibility adherence. For further information, or if you are having difficulty accessing this site, please .
