WS-HT standard specification
OASIS Group is an international consortium that drives open source adoption of standards.
It has defined the WS-HT specification to standardize human interactions, their structure
and information, and make them interoperable between different vendors. The WS-HT spe-
cification serves as a guideline of the features that every human component should have; it
is based on industrial best practices and on the most implemented end user features. Being
compliant with this kind of specification will help you to replace components provided by
one vendor with the components of another vendor without affecting other components, as
long as both vendors apply the same standards.
Most BPM systems architectures provide a built-in component that is in charge of handling
human interactions. This becomes a problem when trying to expose human interactions to
other systems, besides the BPM system. It is because of this reason that even if jBPM6
provides a built-in Human task component, it can be created as a standalone component,
accessible through external services. The overall structure for a jBPM6 BPM system core,
considering only the main components relevant to our current scenario, looks like the fol-
lowing figure:
