There are various kinds of relationship with media in a process of 'learning'. Here we consider a dominant model in which documents are in some way presumed to embody 'knowledge' - as distinct, for example, from enabling a practice of active knowing, in either a reader-user or a writer-producer; or both.
The dominant model of repos of digital documents for 'learning' is wikipedia. Here we have federation of authorship, in relation to a single-topic document, hyperlinked with other single-topic documents - all of them 'anonymous'.

Whatever, it's a hegemonic paradigm of a cultural commons: - open contribution/curating, plus - open access, plus - disciplined moderating/stewarding of texts under quite generously applied rules
