Abstract
A data retrieval system includes a data server which retrieves a data object from a data repository and a system for associating a virtual place with a retrieved data object. The virtual place provides co-presence to users which access the retrieved data object. A method for upgrading a data retrieval system comprised of a data server capable of retrieving data objects from a data repository and a plurality of data-retrieval clients is aLso described. The method includes the steps of adding a co-presence server comprising at least one virtual place associated with one of said data objects and upgrading at least two of said data-retrieval clients with the following abilities: a) the ability to open a separate communication channel with said co-presence server; b) the ability to map retrieved data objects to said virtual places; c) the ability to display co-presence information; d) the ability to enable users to communicate; and e) the ability to notify said co-presence server when said data-retrieval client is terminated.
