Abstract

A presence server includes a receiver to receive a variety of publishing and subscribe requests from a variety of sources; a plurality of elements to process the requests; and a presence manager to flexibly configure the elements as a function of the type of the requests received. A method for processing presence information includes receiving a variety of publishing and subscribe requests from a variety of sources; processing the requests with a plurality of elements; and configuring the elements as a function of the type of the requests received.

Claims

1. A presence server comprising:

a computing device including;

a receiver for receiving a variety of publishing and subscribe requests from a variety of sources;

a plurality of elements for processing the requests; and

a presence manager for flexibly configuring the plurality elements as a function of a type of the requests received;

wherein the plurality of elements comprises;

a plurality of aggregators, each aggregator aggregating presence segments from one type of entity;

an aggregator manager for analyzing an incoming publishing request and for activating at least one of the aggregators which is compatible with the incoming publishing request; and

an external provider manager for retrieving rich presence information, associated with a publishing request from an external provider, wherein the rich presence information is not included in the associated publishing request, to enhance information provided in the associated publishing request.

2. The presence server according to claim 1, wherein the sources comprise at least one of the following entities:

a computer, a cell phone, a telephone, a personal digital assistant, a printer, and a fax machine.

3. The presence server according to claim 1, wherein the aggregators are removable.

4. The presence server according to claim 1, wherein the plurality of elements comprises a resource list manager for retrieving a list of resources from at least one resource list.

5. The presence server according to claim 4, wherein the resource list manager comprises means for accessing a URL to receive a requested resource list and means for providing the resource list to the presence manager.

6. The presence server according to claim 5, wherein the presence manager comprises a processing system for processing an individual subscribe request for each member of the resource list.

7. The presence server according to claim 1, wherein the external provider manager retrieves the rich presence information from the at least one external provider in response to a subscribe request.

8. A method for processing presence information comprising:

receiving a variety of publishing and subscribe requests from a variety of sources;

processing, using a computer device, the requests with a plurality of elements; and

configuring the elements as a function of a type of the requests received;

wherein the processing comprises;

analyzing each publishing request received from a logical entity to determine its type;

selecting an appropriate aggregator from among a set of pluggable aggregators to process each type of request;

aggregating presence information segments from each type;

receiving rich presence information, associated with a publishing request from an external provider, wherein the rich presence information is not included in the associated publishing request; and

including the rich presence information in a presence information document to enhance information provided in the associated publishing request.

9. The method according to claim 8, wherein the processing comprises:

selecting an associated document processor to process each segment; and

creating a presence information document by manipulating and verifying all the segments from the logical entity.

10. The method according to claim 8, wherein the sources comprise at least one of the following entities:

a computer, a cell phone, a telephone, a personal digital assistant, a printer, and a fax machine.

11. The method according to claim 8, wherein the processing comprises:

forwarding, in response to a subscribe request associated with a list of resources, a request for the list of resources to a resource list registry;

receiving the resource list from the resource list registry; and

creating a subscription for each member of the resource list.

12. The method according to claim 8, further comprising:

receiving a subscribe request for the rich presence information; and

retrieving the rich presence from the at least one external provider in response to the subscribe request.

13. A computer product stored on a non-transitory storage medium and readable by a computing system, embodying a program of instructions executable by the computing system for processing presence information, for performing the steps of:

receiving a variety of publishing and subscribe requests from a variety of sources;

processing the requests with a plurality of elements; and

configuring the elements as a function of a type of the requests received;

wherein the processing comprises;

analyzing each publishing request received from a logical entity to determine its type;

selecting an appropriate aggregator from among a set of pluggable aggregators to process each the type of request;

aggregating presence information segments from each type;

receiving rich presence information, associated with a publishing request from an external provider, wherein the rich presence information is not included in the associated publishing request; and

including the rich presence information in a presence information document to enhance information provided in the associated publishing request.

14. The computer product according to claim 13, wherein the processing comprises:

selecting an associated document processor to process each segment; and

creating a presence information document by manipulating and verifying all the segments from the logical entity.

15. The computer product according to claim 13, wherein the sources comprise at least one of the following entities:

a computer, a cell phone, a telephone, a personal digital assistant, a printer, and a fax machine.

16. The computer product according to claim 13, wherein the processing comprises:

forwarding, in response to a subscribe request associated with a list of resources, a request for the list of resources to a resource list registry;

receiving the resource list from the resource list registry; and

creating a subscription for each member of the resource list.

17. The computer program product according to claim 13, further comprising:

receiving a subscribe request for the rich presence information; and

retrieving the rich presence from the at least one external provider in response to the subscribe request.
