Fuente: Wipo "digitalization" A system identifies purchasable digital content to be used in development of a digital composition by receiving a request to identify a set of digital content, and retrieving access history for individual portions of digital content that match the request. The access history includes a number of times the individual portions of digital content have been accessed. The system then produces a set of digital content indicative of the access history for each individual portion of digital content, and outputs the set of digital content that matches the request, and that reflects the access history for individual portions of digital content.
