Abstract

A method for providing an extensible agent comprises receiving a request from a client. One or more environment characteristics is then determined. At least a portion of a plurality of agent components are dynamically selected based on the client request and the environment characteristics. The client request is processed using the selected agent components.

13. A method for providing an extensible agent comprising:

receiving a request from a client;

selecting one or more characteristics of the client request;

determining one or more environment characteristics;

dynamically selecting at least a portion of a plurality of agent components based on the selected one or more characteristics of the client request and the one or more environment characteristics, the at least a portion of the plurality of agent components being selected using a relational knowledgebase that comprises a properties table of properties for dynamic agent component selection and an actions table of actions for processing;

processing the client request using the selected agent components and according to one or more actions of the actions table that are planned and scheduled; and

storing the selected one or more characteristics of the client request in one of the selected agent components,

one of the selected agent components comprising an object to process a structured query language (SQL) statement operable to query a database.

14. Software for providing an extensible agent, the software being embodied in a non-transitory computer-readable medium and when executed operable to:

migrate a plurality of agent components to an environment;

after the migrating, receive a request from a client;

select one or more characteristics of the client request;

determine one or more environment characteristics;

dynamically select at least a portion of the plurality of agent components based on the selected one or more characteristics of the client request and the one or more environment characteristics, the at least a portion of the plurality of agent components being selected using a relational knowledgebase that comprises a properties table of properties for dynamic agent component selection and an actions table of actions for processing; and

automatically process the client request using the selected agent components and according to one or more actions of the actions table that are planned and scheduled.

15. The software of claim 14, each agent component comprising an object defined in an object-oriented programming language.

16. The software of claim 15, further operable to instantiate the selected agent components.

17. The software of claim 16, further operable to register each instantiated agent component.

18. The software of claim 15, at least a portion of the plurality of agent components comprising objects based on a common parent class, the common parent class comprising component messaging and component location logic.

19. The software of claim 14, further operable to store the selected one or more characteristics of the client request in one of the selected agent components.

20. The software of claim 19, one of the selected agent components comprising an object to process a structured query language (SQL) statement operable to query a database.

21. The software of claim 14, the client comprising a remote client and wherein the client request is received through a web server.

22. The software of claim 21, further operable to communicate a web-enabled message to the remote client based on the processed request.

23. The software of claim 14, wherein at least a portion of the plurality of agent components comply with Foundation for Intelligent Physical Agents (FIPA) standards.
