In this proposal, I would prefer that these sentences (proposed for 6.1.1):
“Depending on the caller's role, the referenced task MUST be in a state
listed as valid pre state. In all other cases, the operation MUST be
rejected and MUST NOT cause a task state transition.”
be replaced with something like the following:
“Depending on the caller's role, the referenced task MUST be in a state
listed as valid pre state or in a vendor-extension state. If the task is in
any standard state that is not one of the valid pre states then the
operation MUST be rejected and MUST NOT cause a task state transition. If
the task is in a vendor-defined extension state then the operation MAY be
allowed or MAY be rejected.”

Subject: [bpel4people] BP-20 Proposal
This is a proposal for issue BP-20. I will walk you through the overview
slides at the f2f meeting.
For an overview, please see the attached document "BP-20 -
Extensibility.ppt",
(See attached file: BP-20 - Extensibility.ppt)
Changes in WS-HT types XML Schema ("ws-humantask-types.xsd")
Replace simple type definition of task status (lines 157-170):
<xsd:simpleType name="tStatus">
<xsd:restriction base="xsd:string"/>
</xsd:simpleType>
Add documentation of predefined task status values (definition only, not
referenced anywhere):
<xsd:simpleType name="tPredefinedStatus">
<xsd:restriction base="xsd:string">
<xsd:enumeration value="CREATED" />
<xsd:enumeration value="READY" />
<xsd:enumeration value="RESERVED" />
<xsd:enumeration value="IN_PROGRESS" />
<xsd:enumeration value="SUSPENDED" />
<xsd:enumeration value="COMPLETED" />
<xsd:enumeration value="FAILED" />
<xsd:enumeration value="ERROR" />>
<xsd:enumeration value="EXITED" />
<xsd:enumeration value="OBSOLETE" />>
</xsd:restriction>
</xsd:simpleType>
Changes in WS-HT Specification
Section 6.1.1 – participant operations - add definition of all pre and
post states (lines 1793):
See attached document "Task State Transitions.xls"
(See attached file: Task State Transitions.xls)
Section 6.1.1 – participant operations - add normative (!) language
about task pre and post states (lines 1794):
Any of the listed operations MUST only be invoked by callers having
proper authorization.
Depending on the caller's role, the referenced task MUST be in a
state listed as valid pre state.
In all other cases, the operation MUST be rejected and MUST NOT cause
a task state transition.,
After the operation has successfully completed, the task MUST be in
the post state defined for the operation.
Section 4.7 – update state diagram (line 1581) - fix some state
transitions - may be split off of this extensibility issue, however, it is
a very small update ...
Change "activate" (Created -> Ready/Reserved) to "activation",
Change "revoke" (Reserved/InProgress -> Ready) to "release"
See attached document "State Diagram HT.vsd"
(See attached file: State Diagram HT.vsd)
