Method for storing content, method for consulting content, method for managing content and content readers

A method for storing content implemented by a first content reader. The first content reader includes a processor, a first memory for storing content, a virtualisation layer and a material abstraction layer. The method includes, during storage of first content in a given format, generating first standalone content, following which the first standalone content is stored in the first memory. Generating the first standalone content includes creating first container in which are stored at least the first content to be stored in the given format, and a first access processing step adapted to the given format and associated with the first content to be stored, the data stored in the first container making up the first standalone content. Thus, access to the stored content is guaranteed while the content reader is capable of implementing the access processing step stored with the content in the standalone content.
