Abstract: The invention consists of a new form of digital media document comprising content, applications and services that facilitate sharing and social expression on the Internet within a unified media object instead of being confined to specific websites such as social-networking services. This invention transforms content into content which is reusable, particularly for social expression, by enabling encapsulation of said content within an online document. This can be achieved by presenting a set of library applications to the user, where each application connects to a specific third-party web service, and presents the third-party service reusable content to the user, so the user can reuse in a very simple way, such as drag-and-drop. The invention promotes social engagement with digital multimedia while enabling social expression, commenting and editing of content or of the online document and optionally linking these activities to the website or service timeline.
