    Abstract: PCT No. PCT/GB93/02315 Sec. 371 Date Jun. 27, 1994 Sec. 102(e) Date Jun. 27, 1994 PCT Filed Nov. 10, 1993 PCT Pub. No. WO94/11814 PCT Pub. Date May 26, 1994A programmable workstation for collaborative working in a network comprises a conventional operating system and a network control program layer. Additionally, the workstation includes a collaborative application support subsystem for interfacing with application programs. The subsystem is responsive to predetermined application program calls to create a logical network model of a collaborative environment. The model comprises sharing sets of application programs, which share data and resources across nodes and logical dedicated data channels connecting members of the sharing set. The subsystem cooperates with the network layer to establish the physical links necessary to implement the model in a physical network, transparently to the application program.

    Abstract: A communications system may be used for transmitting and/or receiving data over a network. The communications system includes means responsive to requests for a desired quality of service specifying at least two quality of service parameters, such as bandwidth, latency, error rate, and so on, for determining whether or not the requested quality of service is available. The quality of service requests specify the desired quality of service in terms of logical expressions involving two or more of said at least two quality of service parameters. This allows, for example, a desired quality of service to accept a higher error rate if the available bandwidth is higher. In the preferred embodiment, each quality of service parameter is specified in terms of a range between minimum and a maximum acceptable values.

Date May 26, 1994A programmable workstation for collaborative working in a network comprises a conventional operating system and network control layer for controlling physical routing of data between nodes. A collaborative application subsystem which interfaces with application programs is responsive to a predetermined call from a collaboration call manager to establish the call manager at the node to handle incoming events which are not specific to any application program instances at the node.

    Abstract: A data retrieval system in which a plurality of objects having a multi-level hierarchical relationship are stored is disclosed. Thus, each object has a respective parent and a set of children. The system includes an index table comprising a respective name and associated identifier for each object, and a data table comprising a respective set of attributes and a position key associated with each object in the system. Each position key comprises a series of components, each component corresponding to a level of the hierarchy. A first component of said key stores the identifier of an associated object, and each successive component stores the identifier of the parent of the object stored in the previous component.

    Abstract: A data conferencing system includes at least two computer workstations linked by a data network. Each computer workstation is able to store and display an electronic sheet, the electronic sheet being logically divided into a set of cells, each cell being able to contain a single character. A user can select a portion 370 of the electronic sheet, a portion comprising at least one cell, and then perform different editing operations on the selected portion of the electronic sheet. Updates resulting from editing the electronic sheet are then distributed to the other computer workstations in the data conferencing system, so that all the workstations in the data conferencing system share the same electronic sheet.
