摘要: A multi-user collaborative system in which the contents as well current status of other user activity a shared structured data object (40) representing one or more related objects form entries can be concurrently accessed by different users respectively at workstations (14) connected to common link (12). The what-you-see-is-what-I-see interface representation includes an ordered listing such that are maintained object, and various attributes each listed entry, inter alia , type class entry; revision number object; pages date creation last whether entry and, if not, who has prevented access; local instance is present on user's system; provision for miscellaneous notes comments relative view users. Means provided maintaining information its initiated demand updated basis invoked operation, operation requires implement properly. Further, means locking up individual user, thereby preventing access locked users, prevent concurrent editing changes same two In this connection, modification cannot performed until have been up. Visual indication state entries, time lock, displayed when invokes contents.
