Abstract

Techniques for orchestrating workflows are disclosed herein. In an embodiment, a method of orchestrating a workflow is disclosed. In an embodiment, data is stored in a policy file which associates attributes with processes. User input is received. A process associated with an attribute is selected, where the attribute is based on the user input. The selected process is performed as part of the workflow. Also, processes may be added dynamically as part of any category inside the policy file without having to recompile or redesign the logic of the BPEL project.

First claim

What is claimed is:

1. A method, comprising:
receiving user input associated with a user, the user input comprising a request that identifies a process to be performed for a user and a user role associated with the user;
identifying, from a policy file, a set of one or more child processes corresponding to the process to be performed for the user;
identifying, from the policy file, a set of one or more web services for performing a child process of the set of one or more child processes corresponding to the process associated with the request;
determining, from the policy file, that a first web service in the set of one or more web services is related to a first user role associated with the user;
determining, from the policy file, that a second web service in the set of one or more web services is related to a second user role associated with the user;
invoking, from the policy file, the first web service when the user role comprises the first user role;
invoking, from the policy file, the second web service when the user role comprises the second user role; and
transmitting a notification of completion of the process based at least in part on performance of each child process by the set of one or more child processes of the process.

2. The method of claim 1 , further comprising storing the policy file in a data store, the policy file associating user roles with the set of one or more child processes corresponding to the process, the user roles identifying roles of users associated with the user input.

3. The method of claim 1 , further comprising:
invoking, in response to receiving the user input, at least one web service of the set of one or more web services to read the policy file;
receiving a payload from the at least one web service based at least in part on the policy file; and
identifying each child process of the set of one or more child processes of the process based at least in part on the payload.

4. The method of claim 3 , wherein the process is defined as a business process execution language (BPEL) process, and wherein the at least one web service is a child process of the BPEL process.

5. The method of claim 4 , wherein the payload comprises information indicating the set of one or more child processes to be performed as part of the BPEL process.

6. The method of claim 1 , wherein the policy file groups the set of one or more child processes into categories and wherein identifying the set of one or more child processes includes invoking a category of the policy file based at least in part on the user input.

7. The method of claim 1 , further comprising modifying the policy file to specify a different web service of the set of one or more web services to be invoked for performing a different set of one or more child processes based at least in part on the user role.

8. A non-transitory computer-readable storage medium having stored thereon instructions for causing at least one processor to perform the instructions, comprising:
instructions for causing the at least one processor to receive user input associated with a user, the user input comprising a request that identifies a process to be performed for the user and a user role associated with the user;
instructions for causing the at least one processor to identify, from a policy file, a set of one or more child processes corresponding to the process to be performed for the user;
instructions for causing the at least one processor to identify, from the policy file, a set of one or more web services for performing a child process of the set of one or more child processes corresponding to the process associated with the request;
instructions for causing the at least one processor to determine, from the policy file, that a first web service in the set of one or more web services is related to a first user role associated with the user;
instructions for causing the at least one processor to determine, from the policy file, that a second web service in the set of one or more web services is related to a second user role associated with the user;
instructions for causing the at least one processor to invoke, from the policy file, the first web service when the user role comprises the first user role;
instructions for causing the at least one processor to invoke, from the policy file, the second web service when the user role comprises the second user role; and
instructions for causing the at least one processor to transmit a notification of completion of the process based at least in part on performance of each child process by the set of one or more child processes of the process.

9. The computer-readable storage medium of claim 8 , further comprising instructions for causing the at least one processor to store the policy file in a data store, the policy file associating user roles with the set of one or more child processes corresponding to the process, the user roles identifying roles of users associated with the user input.

10. The computer-readable storage medium of claim 8 , further comprising instructions for causing the at least one processor to:
invoke, in response to receiving the user input, at least one web service of the set of one or more web services to read the policy file;
receive a payload from the at least one web service based at least in part on the policy file; and
identify each child process of the set of one or more child processes of the workflow based at least in part on the payload.

11. The computer-readable storage medium of claim 10 , wherein the process is defined as a business process execution language (BPEL) process and wherein the at least one web service is a child process of the BPEL process.

12. The computer-readable storage medium of claim 11 , wherein the payload comprises information indicating the set of one or more child processes to be performed as part of the BPEL process.

13. The computer-readable storage medium of claim 8 , wherein the policy file groups the set of one or more child processes into categories, and wherein identifying the set of one or more child processes includes invoking a category of the policy file based at least in part on the user input.

14. The computer-readable storage medium of claim 8 , further comprising instructions for causing the at least one processor to modify the policy file to specify a different web service of the set of one or more web services to be invoked for performing a different set of one or more child processes based at least in part on the user role.

15. A system, comprising:
a processor; and
a memory subsystem including instructions that, when executed by a processor, cause the processor to:
receive user input associated with a user, the user input comprising a request that identifies a process to be performed for the user and a user role associated with the user;
identify, from a policy file, a set of one or more child processes corresponding to the process to be performed for the user;
identify, from the policy file, a set of one or more web services for performing a child process of the set of one or more child processes corresponding to the process associated with the request;
determine, from the policy file, that a first web service in the set of one or more web services is related to a first user role associated with the user;
determine, from the policy file, that a second web service in the set of one or more web services is related to a second user role associated with the user;
invoke, from the policy file, the first web service when the user role comprises the first user role;
invoke, from the policy file, the second web ser
