Human tasks - APIs
The Human task component exposes a set of APIs that are also based on the WS-HT stand-
ard specification, which is defined in the
https://incubator.apache.org/hise/WS-Hu-
manTask_v1.pdf
.
The API's responsibility is to provide us with a way to handle human
tasks from the user interfaces in a task-list-oriented way. Those APIs are also used by the
process engine to create tasks and register themselves for listening to changes on each task
(specifically, completion, failure, or skipping of the tasks that the process engine created).
It is important to understand at this point that the Human task component itself doesn't need
to understand anything about processes. It merely provides a framework to work with hu-
man tasks. It is the process engine that will depend on this component if it has processes
with human tasks defined in them.
User UIs will use the APIs provided by the task service to provide task lists with relevant
tasks for different groups and users and also to populate and complete forms that represent
tasks performed by people.
