In this proposal, I would prefer that these sentences (proposed for 6.1.1):

â€œDepending on the caller's role, the referenced task MUST be in a state listed as valid pre state. Â In all other cases, the operation MUST be rejected and MUST NOT cause a task state transition.â€

be replaced with something like the following:

â€œDepending 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.Â If the task is in a vendor-defined extension state then the operation MAY be allowed or MAY be rejected.â€

This is a proposal for issue BP-20. I will walk you through the overview slides at the f2f meeting.

Â Â For an overview, please see the attached document "BP-20 - Extensibility.ppt", Â Â (See attached file: BP-20 - Extensibility.ppt)

Changes in WS-HT types XML Schema ("ws-humantask-types.xsd")

Â Â Replace simple type definition of task status (lines 157-170): Â Â Â Â Â <xsd:simpleType name="tStatus"> Â Â Â Â Â Â Â Â <xsd:restriction base="xsd:string"/> Â Â Â Â Â </xsd:simpleType>

Â Â Add documentation of predefined task status values (definition only, not referenced anywhere): Â Â Â Â Â <xsd:simpleType name="tPredefinedStatus"> Â Â Â Â Â Â Â Â <xsd:restriction base="xsd:string"> Â Â Â Â Â Â Â Â Â Â Â <xsd:enumeration value="CREATED" /> Â Â Â Â Â Â Â Â Â Â Â <xsd:enumeration value="READY" /> Â Â Â Â Â Â Â Â Â Â Â <xsd:enumeration value="RESERVED" /> Â Â Â Â Â Â Â Â Â Â Â <xsd:enumeration value="IN_PROGRESS" /> Â Â Â Â Â Â Â Â Â Â Â <xsd:enumeration value="SUSPENDED" /> Â Â Â Â Â Â Â Â Â Â Â <xsd:enumeration value="COMPLETED" /> Â Â Â Â Â Â Â Â Â Â Â <xsd:enumeration value="FAILED" /> Â Â Â Â Â Â Â Â Â Â Â <xsd:enumeration value="ERROR" />> Â Â Â Â Â Â Â Â Â Â Â <xsd:enumeration value="EXITED" /> Â Â Â Â Â Â Â Â Â Â Â <xsd:enumeration value="OBSOLETE" />> Â Â Â Â Â Â Â Â </xsd:restriction> Â Â Â Â Â </xsd:simpleType>

Changes in WS-HT Specification

Â Â Section 6.1.1 â€“ participant operations - add definition of all pre and post states (lines 1793): Â Â Â Â Â See attached document "Task State Transitions.xls" Â Â Â Â Â (See attached file: Task State Transitions.xls)

Â Â Section 6.1.1 â€“ participant operations - add normative (!) language about task pre and post states (lines 1794): Â Â Â Â Â Any of the listed operations MUST only be invoked by callers having proper authorization. Â Â Â Â Â Depending on the caller's role, the referenced task MUST be in a state listed as valid pre state. Â Â Â Â Â In all other cases, the operation MUST be rejected and MUST NOT cause a task state transition., Â Â Â Â Â After the operation has successfully completed, the task MUST be in the post state defined for the operation.

Â Â Section 4.7 â€“ update state diagram (line 1581) - fix some state transitions - may be split off of this extensibility issue, however, it is a very small update ... Â Â Â Â Â Change "activate" (Created -> Ready/Reserved) to "activation", Â Â Â Â Â Change "revoke" (Reserved/InProgress -> Ready) to "release" Â Â Â Â Â See attached document "State Diagram HT.vsd" Â Â Â Â Â (See attached file: State Diagram HT.vsd)
