Subject: [bpel4people] Issue BP-63 - Actual Owner Missing in WS-HumanTask Context -Resolution Proposal
As discussed at the F2F on Jan 22, I propose to make the following
modifications to the WS-HumanTask context (WS-HumanTask section 7.4 and
ws-humantask-context.xsd).
(1) Split the humanTaskContext element into two separate elements for the
request and the response, and factor out the common elements into a base
type extended by both request and response context.
(2) Add the actualOwner as well as other generic human roles (as mandatory
elements) to the response context in order to communicate the effective
human role assignments back to the task parent.
(3) Enable extensibility for both request and response context.
(4) Unblock substitution for the contained genericHumanRole element
(similar to Issue BP-62).
As a result, this is what the WS-HumanTask context
(ws-humantask-context.xsd) looks like:
