<p>Many different users may access, revise and update the same shared object simultaneously through several different transports. Clients may communicate asynchronously by accessing the shared object through a physical server. Clients may also communicate synchronously by accessing the shared object through a peer-to-peer network. A manifest file associated with the shared object identifies the locations where other versions and instances of the shared object are stored. The shared object and the associated manifest file allow a client to transition seamlessly between local access, synchronous and asynchronous communication such that the user is not aware that the mode of communication has changed. A user may change location and any available data sharing transports are automatically identified. Thus, the user may access a shared object and collaborate with other authorized users through different mechanisms.</p> |
