Metadata and information structure design on websites - towards a web for all

When we transmit information through the internet, we would usually like it to reach many people. Our aim is for people to read it, to utilise it as a source, and to make use of it in their studies, e.g., in postgraduate courses, or in other fields of life. This article seeks to identify what elementary criteria our information source has to fulfil in order for search engines to find it, for users to consider it relevant and appropriate, and for it to meet the demands of users with disabilities. Only if these criteria are fulfilled does our website become really accessible. To promote this possibility, the article deals with the theoretical and practical dimensions of screen structure, data structure and metadata.
