“Taxonomy and metadata are becoming much more popular these days. Companies need to keep track of their information, but can’t use traditional classification systems, such as Dewey Decimal or Library of Congress Subject Headings. In the last 10 years, faceted taxonomies have taken on new importance on the web; XML has upgraded the visibility of metadata. Having the skills to create taxonomies and metadata will serve you well. Most people don’t have the instinctual skills to create information organization structures that are useful or the practical knowledge and experience to be confident in the structures they create. Understanding how taxonomies and metadata feed into user interfaces allows you to recommend good designs that improve findability.”
Taxos and metadata have been around for centuries. Locked in the paper technologies.
