Abstract

A method for assembling parametric information processing applications, includes: receiving a composition request; composing a processing graph for the request, wherein the processing graph represents an application that includes at least one component; identifying a deployment parameter of the component and requesting a value of the parameter; receiving the parameter value; applying the parameter value to the application; and deploying the application with the parameter value in an execution environment.

Claims

1. A method for assembling parametric information processing applications, comprising:

receiving a composition request;

composing a processing graph for the request, wherein the processing graph represents an application that includes at least one component;

identifying a deployment parameter of the component and requesting a value of the parameter;

receiving the parameter value;

applying the parameter value to the application; and

deploying the application with the parameter value in an execution environment.

2. The method of claim 1, wherein the deployment parameter is a configuration parameter of the component.

3. The method of claim 1, further comprising:

storing the received parameter value as a default parameter value.

4. The method of claim 3, further comprising:

presenting the default parameter value to a user when requesting a value of the parameter.

5. The method of claim 1, wherein the parameter value request prompts a user to manually enter the value into a field on a user interface.

6. The method of claim 1, further comprising:

receiving a request to execute the deployed application;

identifying an execution parameter for the deployed application and requesting a value of the execution parameter;

receiving the value of the execution parameter;

invoking the deployed application according to the received execution parameter value; and

returning a response provided by the invoked application.

7. The method of claim 1, further comprising:

receiving a request to reconfigure the deployed application;

identifying a reconfiguration parameter for the deployed application and requesting a value of the reconfiguration parameter;

receiving a reconfiguration parameter value; and

reconfiguring the deployed processing graph with the reconfiguration parameter value.

8. The method of claim 7, wherein the reconfiguration parameter is a configuration parameter of a component in the deployed application.

9. The method of claim 1, wherein the deployment parameter is a parameter operator instance in the processing graph.

10. The method of claim 9, wherein at least one prompt for each parameter operator instance is presented to a user.

11. The method of claim 1, wherein if two deployment parameters are identified that are the same only one parameter value needs to be entered.

12. A method for assembling parametric information processing applications, comprising:

receiving a composition request;

composing a processing graph for the request, wherein the processing graph represents an application that includes at least one component;

deploying the application in an execution environment;

identifying an execution parameter of the component in the deployed processing graph and requesting a value of the parameter;

receiving the parameter value;

invoking the deployed application according to the execution parameter value; and

returning a response provided by the invoked application.

13. The method of claim 12, further comprising:

storing the received parameter as a default parameter value.

14. The method of claim 13, further comprising:

presenting the default parameter value to a user when requesting a value of the parameter.

15. The method of claim 12, wherein the parameter value request prompts a user to manually enter the value in text into a field on a user interface.

16. The method of claim 12, further comprising:

receiving a request to reconfigure the deployed application;

identifying a reconfiguration parameter for the deployed application and requesting a value of the reconfiguration parameter;

receiving a reconfiguration parameter value;

reconfiguring the deployed processing graph with the reconfiguration parameter value.

17. The method of claim 16, wherein the reconfiguration parameter is a configuration parameter of a deployed component.

18. The method of claim 16, further comprising:

deploying the reconfigured processing graph in the execution environment;

invoking the deployed reconfigured processing graph according to the execution parameter value; and

returning a response provided by the invoked processing graph.

19. The method of claim 12, further comprising:

identifying a deployment parameter of the component and requesting a value of the parameter;

receiving the parameter value;

applying the parameter value to the application; and

wherein the application is deployed with the parameter value.

20. A method for applying parameters at different stages in the lifecycle of a composed application represented by a processing graph, comprising:

composing an application in response to a user-specified goal, wherein the application is represented by a processing graph;

deploying the processing graph in an execution environment in a deployment stage; and

invoking the deployed processing graph in the execution environment in an execution stage,

wherein parameter values are applied to the processing graph in the deployment stage if there are any parameters in the processing graph that require user-input prior to deployment, or

wherein parameter values are applied to the processing graph in the execution stage if there are any execution parameter requests.
