Distributed hypertext systems may be considered the best way of fully exploiting the potential of the present global computer network. A fully distributed hypertext, i.e. not a simple client-server system with a centralized database, generates new problems regarding access control, user policies, etc. One such problem regards versioning, though this might not be immediately obvious: the possibility of creating links and other modifications (such as annotations, underlinings, etc.) is seriously impaired without a complete and automatic versioning mechanism to update all external references on demand. Session-based versioning (in contrast with user-decided versioning) appears to be the most satisfactory method of obtaining full distribution and free linking capabilities at the same time. Versioning enables the system to implement static references, always referring to the same data and dynamic ones which are updated to the corresponding data in the latest version. RHYTHM is a prototypical distributed hypertext system with free linking, inclusion, multi-authoring and versioning capabilities. It has tackled problems arising from distribution and versioning, both from a structural and from a cognitive point of view, and has proposed solutions for some of them.
