OK, Bill... THANKS! So it looks like you got in all the changes you are 
comfortable with right now? I'm happy to leave the managed entity / agent 
alone until we resolve the discussion.

Ira and Harry

Sorry to take so long to get to these. I have, except as indicated below 
or where there appeared to be typos, included the changes identified in 
Ira's message. In some cases, I have rearranged text. I have not yet done 
the font-matter/standard format change. Nor have I added the high level 
explanation of multiple managers and multiple schedules which I believe 
are necessary.

Although there are some places that the change from managed entity to 
agent are necessary, I want keep the idea of a Managed Entity  distinct 
from Agent. I regard the WIMS Agent as an agent to allow the management of 
the Managed Entity. This is particularly necessary for the Legacy Managed 
Entity. Also, in discussing the effects of an action, it is unlikely that 
there will be a config change or state change in the agent, particularly 
if the agent is in a proxy. There may well be a change in the config or 
state of the managed entity. 

I also changed the definition of returned unsupported element definitions 
in Agent Operations.


Thanks,

Bill Wagner

Hi Bill,                                          Thursday (8 July 2004)

Here are the edits I suggest for your latest WIMS protocol spec draft
'wd-wims10-20040628.pdf'.  They are in addition to some typos we found
during last week's telecon.

Cheers,
- Ira

----------------------------------------

(0) Global
    - terminology
  * change 'pwg- WIMS:' to 'pwg-wims:'
  * change 'Managed Entity' to 'Agent' or 'WIMS Agent'
  * change 'Managed Entities' to 'Agents' or 'WIMS Agents'
  * change 'Management Station' to 'Manager' or 'WIMS Manager'

(1) Section 5.1.4 RegisterForManagement
    - we can have both Agent and Manager exchange capabilities here -
><WW>< I know we talk about this, but I am concerned about the value 
versus the cost.><WW><

  * change method signature to

    RegisterForManagement (sourceURI : URI, targetURI : URI
        operations : WIMSOperationsSupported,
        actions : WIMSActionsSupported,
        objects : WIMSObjectsSupported) statusString : StatusString,
        operations : WIMSOperationsSupported,
        actions : WIMSActionsSupported,
        objects : WIMSObjectsSupported,
        schedule : Schedule

  * change highlighted Parameters to

    operations : pwg-sm:WIMSOperationsSupported
    - list of WIMS protocol operations supported by this WIMS Agent.

    actions : pwg-sm:WIMSActionsSupported
    - list of WIMS protocol actions supported by this WIMS Agent.

    objects : pwg-sm:WIMSObjectsSupported
    - list of WIMS objects supported by this WIMS Agent.

  * insert new Returns after statusString and before schedule

    operations : pwg-sm:WIMSOperationsSupported
    - list of WIMS protocol operations supported by this WIMS Manager.

    actions : pwg-sm:WIMSActionsSupported
    - list of WIMS protocol actions supported by this WIMS Manager.

    objects : pwg-sm:WIMSObjectsSupported
    - list of WIMS objects supported by this WIMS Manager.
><WW>< I indicated that the Manager actions and objects should be a subset 
of the reported Agent Actions and Objects. Manager operations are 
distinct.><WW><

(2) Section 5.2.2 ExecuteAction
    - my mistake - I will fix Schedule to add the Action union element

  * change method signature to

    ExecuteAction (sourceURI : URI, targetURI : URI, action : Action)
        statusString : StatusString,
        unsupportedElements : UnsupportedElements

  * change Parameters to

    action : pwg-sm:Action
    - single action for immediate execution - this Action instance MUST
    conform to the XML Schema defined in the PWG Semantic Model [PWG-SM]
    module 'Schedule.xsd'.

(3) Section 5.3 WIMS Monitoring Actions
    - editorial fixups to align with Schedule schema

  * change entire second paragraph to

    This section defines WIMS monitoring actions that are benign and
    intended not to disrupt the normal operation of the WIMS Agent.
    Therefore, support for WIMS monitoring actions is REQUIRED for all
    WIMS Agents and WIMS Managers.  This does not preclude the local
    configuration of policies disallowing certain actions, particularly
    with respect to certain elements or values.  For example, certain
    elements or resources may be may be regarded as private information
    and may be made inaccessible.

(4) Section 5.3.2 GetResources
  * change method signature to

    GetResources (targetURIs : URI,
        requestedResources : RequestedResources,
        parameters : any)

  * change Parameters to

    requestedResources : pwg-sm:ActionRequestedResources
    - list of requested resources specified by ResourceId values (keys),
    ResourceName values (local names), and/or a resource filter (set of
    resource elements and values that all MUST be satisified for match).


(5) Section 5.3.3 SubscribeForAlerts
  * change method signature to

    SubscribeForAlerts (targetURIs : URI, notifyrecipientURI : URI,
        notifyEvents : NotifyEvents, notifyElements : NMTOKEN,
        subsciptionElements : any, parameters : any)

  * change Parameters to

    notifyRecipientURI : xsd:anyURI
    - URI of the WIMS Manager to be notified - this value MUST use the
    'pwg-wims:' URL scheme and MUST conform to [RFC2396].

    notifyEvents : pwg-sm:NotifyEvents
    - list of event names to be delivered via SendAlert and defined in
    the PWG Semantic Model [PWG-SM] module 'Events.xsd'.

    subscriptionElements : pwg-sm:ActionElementAny
    - optional fully qualified names and strongly typed values of
    Subscription object elements defined in the PWG Semantic Model
    [PWG-SM] module 'Alert.xsd'.  Support by WIMS Agents of 'visible'
    Subscription objects (can be queried with GetElements) is OPTIONAL.

(6) Section 5.3.4 UnsubscribeForAlerts
    - editorial fixup to align with Schedule schema

  * change Description to

    Cancel subscription for event delivery via SendAlert.  WIMS Agent
    MUST send a SendReport to the configured WIMS Manager.

(7) Section 5.4
    - editorial fixups to align with Schedule schema

  * change title to

    5.4 WIMS Administration Actions

  * change beginning of first sentence to

    Each of the administration actions

  * change entire second paragraph to

    This section defines WIMS administration actions that all cause
    immediate state changes and may disrupt operation of the WIMS Agent.
    Therefore, support for WIMS administration actions is OPTIONAL for
    all WIMS Agents and WIMS Managers.  These actions will result in an
    WIMS SendAlert operation only if the Schedule also includes a
    SubscribeForAlerts action specifying the corresponding state change
    events, or if the actions fail.

(8) Section 5.4.1 Vendor
    - editorial fixup to align with Schedule schema
  * move entire section to section 5.5 WIMS Management Actions
    - to allow use of vendor extension operations _without_ support for
      any of the more powerful WIMS administration actions


(9) Section 5.5

  * change title to

    5.5 WIMS Management Actions

  * change beginning of first sentence to

    Each monitoring action

  * change entire second/third paragraphs to

    This section defines WIMS management actions that may indirectly
    cause state changes or disrupt operation of the WIMS Agent.
    Therefore, support for WIMS management actions is OPTIONAL for
    all WIMS Agents and WIMS Managers.  These actions all result in an
    WIMS SendReport operation to confirm action success or failure.

(10) Section 5.5.1 SetElements

  * change method signature to

    SetElements (targetURIs : URI,
        targetElements : any
        mandatoryElements : NMTOKEN
        resetMode : restartMode
        parameters : any)

  * change Parameters to

    mandatoryElements : xsd:NMTOKEN
    - fully qualified names of the mandatory elements that MUST all be
    successfully set or else this SetElements action MUST fail.

    resetMode : pwg-sm:ActionRestartModeType
    - reset mode (none, current configuration cold boot, current
    configuration warm boot, previous good configuration, factory
    default configuration).  If this parameter is missing or 'None',
    then the specified target elements are NOT reset to a previous
    configuration but are instead explicitly set to the newly requested
    values.  This parameter supports reset of selected elements to their
    previous values without requiring a Restart of the WIMS Agent.

(11) Section 5.5.2 DeleteResources
    - see section 5.3.2 GetResources above

  * change method signature to

    DeleteResources (targetURIs : URI,
        requestedResources : RequestedResources,
        parameters : any)

  * change Parameters to

    requestedResources : pwg-sm:ActionRequestedResources
    - list of requested resources specified by ResourceId values (keys),
    ResourceName values (local names), and/or a resource filter (set of
    resource elements and values that all MUST be satisified for match).

(12) Section 5.5.3 SetResources
    - see section 5.5.1 SetElements above

  * change method signature to

    SetResources (targetURIs : URI,
        targetResources : TargetResources,
        targetElements : any
        mandatoryElements : NMTOKEN
        parameters : any)

  * change Parameters to

    targetResources : pwg-sm:ActionTargetResources
    - list of target resources specified by ResourceId values (keys),
    ResourceName values (local names), and/or a resource filter (set of
    resource elements and values that all MUST be satisified for match).

    targetElements : pwg-sm:ActionElementAny
    - fully qualified names and strongly typed values of target
    elements to be added or modified by this SetResources action.

    mandatoryElements : xsd:NMTOKEN
    - fully qualified names of the mandatory elements that MUST all be
    successfully set or else this SetResources action MUST fail.
