Abstract

Methods and apparatus are disclosed for automatic notification and response based on communication flow expressions having dynamic context. A message is provided from a sender to at least one recipient in accordance with a communication flow having a plurality of potential paths. The communication flow is controlled by a communication flow expression having a dynamic context, wherein the communication flow expression contains at least one primitive keyword indicating how the message should be processed. The dynamic context of the communication flow expression may be established using one or more labels or a context function. A number of primitive keywords are provided that allow a communication flow expression to react to a dynamic context.

Claims

1. A method for providing a message from a sender to at least one recipient in accordance with a communication flow having a plurality of potential paths, said method comprising:

receiving said message from said sender;

evaluating said communication flow, wherein said communication flow is controlled by a communication flow expression having a dynamic context, wherein said communication flow expression contains at least one primitive keyword indicating how said message should be processed; and

processing said message based on said communication flow expression.

2. The method of claim 1, wherein said dynamic context is established using one or more labels.

3. The method of claim 2, wherein said one or more labels are inherited by each child node of the node to which said one or more labels are applied.

4. The method of claim 2, wherein said one or more labels are unique.

5. The method of claim 2, wherein said one or more labels are used as a condition in a communication rule.

6. The method of claim 2, wherein one or more of said labels are tested by a conditional expression in a communication flow.

7. The method of claim 2, wherein said one or more labels are used to identify a subscription that generated a message.

8. The method of claim 2, wherein said one or more labels are tested by one or more communication rules to determine the preferred communication flow for delivering messages based on one or more subscriptions.

9. The method of claim 2, wherein said one or more labels are used to identify phases of a communication.

10. The method of claim 2, wherein said one or more labels are used to identify roles of recipients of a communication.

11. The method of claim 2, wherein said one or more labels are used to control a rendering of said message.

12. The method of claim 1, wherein said primitive keyword is a context function that allows an application to set a context for said communication flow expression that is executed at the root level.

13. The method of claim 12, wherein said context function invokes a method on the root of a subtree created by parsing a second argument of said context function to set said context.

14. The method of claim 13, wherein said method causes said context to propagate down said subtree, setting a context on all nodes that do not currently have a defined context.

15. The method of claim 1, wherein said primitive keyword is an evaluation function that specifies data being watched that will trigger evaluation of a specified conditional.

16. The method of claim 15, wherein said evaluation function acts on changes to one or more of data and responses associated with said communication flow expression.

17. The method of claim 16, wherein said evaluation function allows an application to dynamically add one or more nodes to said communication flow during execution of said communication flow as a result of data updates or receipt of responses.

18. The method of claim 1, wherein said primitive keyword is a watch operand that has an associated test expression that is evaluated at runtime, and wherein said watch operand will block until said associated test expression evaluates to true, and then said watch operand will evaluate to true.

19. The method of claim 18, wherein said watch operand evaluates said associated test expression the first time said associated test expression is encountered and if said associated test expression is false, then said associated test expression is evaluated each time the request data is modified or a response is submitted.

20. The method of claim 18, wherein said watch operand monitors a specific element in the data associated with said communication flow expression, or the responses associated with said communication flow expression and allows iteration over all values, and wherein said watch operand evaluates said associated test expression for each existing value or response, and then when a new value is added for said element being watched, or a new response is submitted.

21. The method of claim 1, wherein said primitive keyword is an advises or informs operator that causes an out-of-band communication flow expression to be evaluated outside of the scope of said main communication flow expression.

22. The method of claim 21, wherein a response received to said out-of-band communication flow expression is treated as a comment and does not affect the truth-value of the said main communication flow expression.

23. The method of claim 1, wherein said primitive keyword is a consult operator that evaluates all of its children and waits for one of them to result in a true or false value.

24. The method of claim 23, wherein said result is returned as the value of the operator, but the remaining operands are placed out-of-band so that they can continue operation without affecting an outcome of said communication flow expression.

25. The method of claim 1, wherein said primitive keyword is a contact function that allows a media contact to be defined directly in said communication flow expression.

26. The method of claim 25, wherein said contact function allows a communication flow to be dynamically delegated to another recipient.

27. An apparatus for providing a message from a sender to at least one recipient in accordance with a communication flow having a plurality of potential paths, said apparatus comprising:

a memory; and

at least one processor, coupled to the memory, operative to;

receive said message from said sender;

evaluate said communication flow, wherein said communication flow is controlled by a communication flow expression having a dynamic context, wherein said communication flow expression contains at least one primitive keyword indicating how said message should be processed; and

process said message based on said communication flow expression.

28. The apparatus of claim 27, wherein said dynamic context is established using one or more labels.

29. The apparatus of claim 27, wherein said primitive keyword is a context function that allows an application to set a context for said communication flow expression that is executed at the root level.

30. The apparatus of claim 27, wherein said primitive keyword is an evaluation function that specifies data being watched that will trigger evaluation of a specified conditional.

31. The apparatus of claim 27, wherein said primitive keyword is a watch operand that has an associated test expression that is evaluated at runtime, and wherein said watch operand will block until said associated test expression evaluates to true, and then said watch operand will evaluate to true.

32. The apparatus of claim 27, wherein said primitive keyword is an advises or informs operator that causes an out-of-band communication flow expression to be evaluated outside of the scope of said main communication flow expression.

33. The apparatus of claim 27, wherein said primitive keyword is a consult operator that evaluates all of its children and waits for one of them to result in a true or false value.

34. The apparatus of claim 27, wherein said primitive keyword is a contact function that allows a media contact to be defined directly in said communication flow expression.
