Abstract
abundance is due to a series of demands in society nowadays, such as the need for mobility, life-long learning and, therefore,
self-learning. At the same time, there is a great interest in the proposal of universally accepted standards and norms that ensure
product quality. In this paper the latter issue is discussed in order to check whether the existing collections of standards and
norms include or may be applied to Web-based resources for the self-learning of languages.
