Kinds of human tasks
The task kind is derived from the task template kind that is assigned during modeling.
The kinds of human tasks are as follows:
- To-do tasks
- This is where a service component (such as a BPEL process) assigns
a task to one or more people as something for them to do. A to-do
task can be implemented either stand-alone or inline.
- Invocation tasks
- This is where a person can "assign" a task to a service component.
In such a case, a person invokes an automated service, such as a BPEL
process.
An invocation task can be implemented either stand-alone or inline. When it is inline, an invocation task allows a person to invoke the operations that a BPEL process exposes through activities, such as receive or pick activities, or event handlers.
- Collaboration tasks
- This is where a person assigns a task to one or more people. This task kind enables a person to share work with other people in a structured
and controlled way.
A collaboration task is stand-alone, in that there is no interaction between it and any other component. It is self-contained and implements a stand-alone human interaction without any reference or interface to another service.
- Administration tasks
- This type of task grants a person administrative powers such as the ability to suspend, terminate, restart, force-retry, or force-complete
a BPEL process. Administration tasks can be set up on either an invoke activity, or the process as a whole.
This type of task is only available within a BPEL process (inline task).
