Abstract

The present invention provides a computer implemented collaboration system and method for accessing multiple domain data sources and allowing data from those sources to be analyzed and manipulated within a multi-user distributed environment where all visualization, processing, and agent applications work collaboratively. In one embodiment, the collaboration system (10) is organized into an N-tier infrastructure including a data management tier (50), an information access tier (52), a services tier (54), and a user interface tier (56). The infrastructure of the collaboration system (10) rides upon a CORBA communications framework. The data management tier (50) includes data sources (112) and provides data management capabilities normally supplied by database management systems. The repository tier (52) is comprised of repository servers (12) and provides adaptive services to make the data maintained within the data sources (112) available to services in the services tier (54) and the client tools in the user interface tier (56). The services tier (54) is comprised of data channel servers (14), a library server (16), a participant server (24), a context server (26), and a document server (28). The services tier (54) maintains the majority of the business logic as applied to a specific domain problem. The user interface tier (56) is comprised of thin client tools (18) that allow the user to interact with the data in the data sources (112).

Claims

1. A computer implemented collaboration system integrating legacy system components, said computer implemented collaboration system comprising:

a plurality of user terminals connected to a data network, wherein a plurality of participants accesses at least one conference within a context via said user terminals;

a data management tier including data sources, at least one of the data sources being a legacy data source;

a repository tier including repository servers, each of said repository servers being associated with one of said data sources, said repository servers accessing data items within their respective associated said data sources using access methods native to their respective associated said data sources to create at least one document including data items selected from their respective associated said data sources, said created at least one document being associated with the at least one conference by at least one of the plurality of participants;

a user interface tier including at least one client tool for displaying the accessed data items within their respective associated said data sources in client tool interfaces displayed on said user terminals;

a services tier including at least one data channel server associated with said created at least one document, said at least one data channel server being created when said created at least one document is associated with said at least one conference, said at least one data channel server including a data model and providing an interface between said repository servers and said at least one client tool, wherein said at least one client tool receives said data model from said at least one data channel server and registers with said at least one data channel server to be informed of events received by said at least one data channel server from said data model; and

at least one extended property associated with each data item within said data sources, a current version of said at least one extended property being maintained within said data model of said at least one data channel server and displayed by said at least one client tool only within said at least one conference with which said created at least one document is associated, whereby the plurality of participants collaboratively access and manipulate selected data items included in said created at least one document associated with said at least one conference using said at least one client tool to solve a problem of said context,

wherein said context and said problem relate to an intelligence gathering and analysis operation, wherein said created at least one document represents at least one of logistics data, signal intelligence-data, terrain data, map data, and image data.

2. The computer implemented collaboration system of claim 1 wherein said at least one extended property comprises one of a visualization property and a control property for use in displaying the data items with said at least one client tool.

3. The computer implemented collaboration system of claim 1 comprising a plurality of client tools displaying the data items within said at least one data source.

4. The computer implemented collaboration system of claim 3 wherein said plurality of client tools include a map viewer, a list viewer, and an X-Y data plotter.

5. The computer implemented collaboration system of claim 1 further comprising:

a query viewing client tool constructing queries for selecting data from said-at least one data source meeting particular criteria; and

a library server providing an interface between said query viewing client tool and said at least one repository server.

6. The computer implemented collaboration system of claim 5 wherein said query viewing client tool constructs at least one of a standing query and a static query.

7. The computer implemented collaboration system of claim 1 further comprising:

a conference manager client tool managing communication between said user terminals.

8. The computer implemented collaboration system of claim 1 wherein said at least one extended property is maintained in said at least one data channel server in a directed a-cyclic graphical form.

9. The computer implemented collaboration system of claim 1 wherein said at least one repository server, said at least one client tool, and said at least one data channel server are implemented within a CORBA framework.

10. The computer implemented collaboration system of claim 1 wherein said user terminals are geographically remote from one another.
