Revetax examines taxonomies that are available on the internet via digital repositories. Explained simply, these repositories store digital content which can be searched, thereby acting as an online library of resources.
Storing digital material in a repository ensures that these resources can be preserved and well-utilised. Too often, websites simply offer links to other sites but after a while the links don't work as material is moved around or removed.
Digital repositories can store a variety of data from resources to entire courses. A repository stores intellectual assets of an organisation.
