Abstract

Plug-ins for instant messaging (IM) systems are described. By using plug-ins in conjunction with IM systems, the functionality of IM systems may be greatly extended. Specifically, in business applications, such as workflow processes, IM provides a more reliable approach to determining actual delivery of messages.

Claims

1. A communication method comprising:

receiving a workflow request from a workflow server, the workflow request being directed to a specified instant messaging (IM) address;

formatting the received workflow request to generate an IM data stream;

tagging the workflow request with an Extensible Markup Language (XML) tag; and

conveying the workflow request to an IM transport protocol object (TPO), the TPO configured for translating the IM data stream to a desired IM protocol, wherein the XML tag includes at least one of the following;

a generic XML tag configured to indicate presence of a workflow-related message and an XML tag configured to indicate the workflow request.

2. The communications method of claim 1, further comprising issuing a query for presence information to the IM server, the presence information being related to the specified IM address.

3. The communications method of claim 2, further comprising receiving presence information from the IM server in response to the query for presence information.

4. The communications method of claim 3, further comprising:

generating an error message in response to receiving presence information indicating that a user is not present; and

conveying the generated error message to the workflow server.

5. A communication method comprising:

receiving a workflow request from a workflow server, the workflow request being directed to a specified instant messaging (IM) address;

formatting the received workflow request to generate an IM data stream;

tagging the workflow request with an Extensible Markup Language (XML) tag;

conveying the workflow request to an IM server;

receiving an IM response from the IM server, the IM response being indicative of a response to the workflow request;

formatting the IM response to generate a workflow response; and

conveying the workflow response to the workflow server, wherein conveying workflow request to the IM server includes conveying the workflow request to an IM transport protocol object (TPO), the TPO configured for translating the IM data stream to a desired IM protocol.

6. The communications method of claim 5, further comprising issuing a query for presence information to the IM server, the presence information being related to the specified IM address.

7. The communications method of claim 6, further comprising receiving presence information from the IM server in response to the query for presence information.

8. The communications method of claim 7, further comprising:

generating an error message in response to receiving presence information indicating that a user is not present; and

conveying the generated error message to the workflow server.
