Abstract

A computer implemented method for processing a collaborative web page. An initiation method is invoked to locate commands within nodes in a tree. The commands may place events in a queue to form queued events. Events are processed on a data hub to deliver the queued events to the data hub. A discover method is invoked on the commands present in the tree for allowing identical commands to update. A render method is invoked on the commands present in the tree to display the commands on the collaborative web page.

Claims

1. A computer implemented method for processing a collaborative web page, the computer implemented method comprising:

invoking an initiation method to locate commands within nodes in a tree, wherein the commands may place events in a queue to form queued events;

processing events on a data hub to deliver the queued events to the data hub;

invoking a discover method on the commands present in the tree for allowing identical commands to update; and

invoking a render method on the commands present in the tree to display the commands on the collaborative web page.

2. The computer implemented method of claim 1, wherein the collaborative web page is a Wiki page, wherein the collaborative web page is part of a Wiki application, wherein the tree is an abstract syntax tree, and wherein the commands are Wiki commands.

3. The computer implemented method of claim 2, further comprising:

creating the abstract syntax tree from the Wiki page.

4. The computer implemented method of claim 3, wherein the creating step is performed by a Wiki command context object and further comprises:

retrieving and parsing markup language of the Wiki page to form the abstract syntax tree.

5. The computer implemented method of claim 1, further comprising:

performing the processing events responsive to invoking an initiation method.

6. The computer implemented method of claim 1, comprising:

repeating the processing events again after invoking the discover method.

7. The computer implemented method of claim 1, wherein the events are generated during invoking the initiation method, processing events, and invoking a render method.

8. The computer implemented method of claim 1, wherein the invoking and processing steps are performed by a command processor of a Wiki engine.

9. The computer implemented method of claim 1, wherein the processing step further comprises:

dequeing the queued events;

delivering the queued events to registered subscribers;

enqueuing any resulting events to form queued events; and

triggering an invoke method command whose input values have been fulfilled by a data delivery mechanism of the data hub.

10. The computer implemented method of claim 1, wherein invoking a discover method further comprises:

establishing a direct event connection between the commands and identical commands, the direct event connection occurs without interaction from the data hub.

11. The computer implemented method of claim 1, wherein invoking a discover method further comprises:

interrogating the data hub for publishers, subscribers, and topics for updating the commands.

12. The computer implemented method of claim 1, further comprising:

updating a set of input values of each of the commands to execute functions of each of the commands.

13. A data processing system comprising:

a bus system;

a communications system connected to the bus system;

a memory connected to the bus system, wherein the memory includes a set of instructions; and

a processing unit connected to the bus system, wherein the processing unit executes the set of instructions to invoke an initiation method to locate commands within each node of a tree, wherein the commands may place events in a queue to form queued events, process events on a data hub to deliver the queued events to the data hub, invokes a discover method on the commands present in the tree for allowing identical commands to update, and invokes a render method on the commands present in the tree to display the commands on the web page.

14. The system of claim 13, wherein the commands update with the identical commands on an interconnected client data processing system.

15. The system of claim 13, wherein the set of instructions are executed by a processing engine, and wherein the set of instructions include a Wiki command context that retrieves and parses the web page into the tree, wherein the tree is an abstract syntax tree.

16. A computer program product comprising a computer usable medium including computer usable program code for processing a web page for a collaborative website, the computer program product comprising:

computer usable program code for invoking an initiation method to locate commands within nodes in a tree, wherein the commands may place events in a queue to form queued events;

computer usable program code for processing events on a data hub to deliver the queued events to the data hub;

computer usable program code for invoking a discover method on the commands present in the tree for allowing identical commands to update; and

computer usable program code for invoking a render method on the commands present in the tree to display the commands on the collaborative web page.

17. The computer program product of claim 16, comprising computer usable program code for retrieving and parsing markup language of the Wiki page to form the abstract syntax tree.

18. The computer program product of claim 16, comprising, further comprising:

computer usable program code responsive to invoking the initiation method for processing events on a data hub to deliver the queued events to the data hub; and

computer usable program code for repeating the processing events again after invoking the discover method.

19. The computer program product of claim 16, further comprising:

computer usable program code for updating a set of input values of each of the commands to execute functions of each of the commands.

20. The computer program product of claim 16, wherein computer usable program code for invoking a discover method comprises:

computer usable program code for establishing a direct event connection between the commands and identical commands, the direct event connection occurs without interaction from the data hub; and

computer usable program code for interrogating the data hub for publishers, subscribers, and topics for updating the commands.
