Abstract

A method and system for providing source information of data being published are provided. The method includes making available source information (311) for a message (310) being published. The source information includes: a topic of the published message (310); any source topics the topic of the published message (310) is derived from; and a message of the published message (310). The method further includes subscribing (314) to source information for a message topic. The subscribing (314) may include recursively subscribing to source information for a source topic in order to obtain live source information for a message (310).

Claims

1. A method for providing source information of data being published, comprising:

making available source information for a message, the source information including;

a message topic; and

any source topics the message topic is derived from;

subscribing to source information for a message topic.

2. The method as claimed in claim 1, wherein making available the source information publishes the source information in the message.

3. The method as claimed in claim 1, wherein making available the source information publishes the source information in a separate topic.

4. The method as claimed in claim 1, wherein the message indicates a live status.

5. The method as claimed in claim 1, wherein subscribing to source information subscribes to source information for a specified message within a topic.

6. The method as claimed in claim 1, wherein subscribing to source information for a message topic results in a hierarchy of source topics on which the message topic is dependent.

7. The method as claimed in claim 1, wherein a subscribing to source information for a message topic includes recursively subscribing to source information for source topics.

8. The method as claimed in claim 6, wherein subscribing to source information for source topics provides the messages for source topics including live status information on the source topics, providing a live network which can be monitored.

9. The method as claimed in claim 8, including checking status information of source topics, and wherein a source topic status is not good, subscribing to the source information for that source topic.

10. The method as claimed in claim 9, including determining if the status of a source topic is not good and, if the source topic is an endpoint, issuing a problem alert.

11. The method as claimed in claim 1, wherein multiple publishers make available source information for a topic and new source information for a topic overwrites existing source information for the topic.

12. The method as claimed in claim 1, wherein multiple publishers make available source information for a topic and the source information is combined using policies.

13. The method as claimed in claim 1, including storing and processing source information at a message broker.

14. A system for providing source information of data being published, comprising:

at least one publisher application including means for making available source information for a message, the source information including;

a message topic; and

any source topics the message topic is derived from;

a message broker including means for storing and processing source information provided by the at least one publisher application; and

a subscriber application subscribing to source information for a topic.

15. The system as claimed in claim 14, wherein the message indicates live status information.

16. The system as claimed in claim 14, wherein the message broker provides a hierarchy of source topics to a subscriber application.

17. The system as claimed in claim 14, including:

means for a subscriber application to subscribe recursively to source information for a source topic.

18. The system as claimed in claim 14, wherein the messages for source topics include live status information on the source topics, providing a live network which can be monitored.

19. The system as claimed in claim 18, including a monitoring means for the live network in the form of a subscriber application monitoring messages of topic hierarchies.

20. The system as claimed in claim 19, wherein the monitoring means includes means for checking status information of topics, and wherein if a topic status is not good, subscribing to the source information for that topic.

21. The system as claimed in claim 20, wherein the monitoring means includes means for issuing a problem alert if a topic is an endpoint and the status is not good.

22. A computer program product stored on a computer readable storage medium, comprising computer readable program code means for performing the steps of:

making available source information for a message, the source information including;

a message topic; and

any source topics the message topic is derived from; and

subscribing to source information for a message topic.
