摘要：A computer system having a facility for concurrently sharing objects orresources is described. The system includes a publish-and- subscribe facility or \"ObjectExchange,\" for facilitating sharing among workgroups. When a data object is \"published\"by a user (\"publisher\"), the object is sent from that user's computer to other computerusers specified by the publisher. Those interested in the published data object (publishedpages) may elect to receive or \"subscribe\" to that data. From that point on, the publishercan choose to update the data, such as whenever the published version changes. The\"subscribers\" of the published pages automatically get updates. Subscribers of aspreadsheet notebook, for instance, would automatically receive pages as they arepublished. The Object Manager effects actions by posting messages or \"forms\" to eitherthe local Object Exchange (assuming one is the publisher) or the Object Exchange ofothers (subscribers). Connectivity for the system is provided by the various ObjectExchange engines negotiating forms. Each Object Exchange posts and retrieves forms atpolling intervals (which may be set to continuous polling). By exploiting the connectivityof existing transport media (e.g., LANs), the present invention delivers workgroup

computing benefits to users, but without imposing a rigid structure which restricts whenand how they work.
