Triggering workflows based on middleware events

A machine-readable medium storing instructions adapted to be executed by a computer to perform a method comprising:

• adding a time-based trigger to a list of time-based triggers if user-specific data is inserted into a memory and is time-sensitive, the memory to queue user-specific data for one or more users for distribution;
• responsive to determining that at least one of the time-based triggers in the list has expired, initiating an operation to act upon the time-sensitive data in memory that is associated with the expired time-based trigger;
• and
• deleting the time-based trigger from the list if the time-sensitive data associated with the respective trigger is removed from the memory.

A system comprising:

• a workflow engine module to generate workflow tasks in conjunction with one or more software application programs, and to monitor progress toward completion of the workflow tasks;
• a middleware module to queue user-specific data associated with workflow tasks for delivery to one or more users, the middleware module including:
• memory to store the queued user-specific data;
• and
• an event generation module to manage the queued user-specific data in the memory that is time sensitive,
• wherein the middleware module is to communicate to the workflow engine module operations executed upon the user-specific data associated with the workflow tasks.
