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.

RE: WBMM> Edits for wd-wims10-20040628.pdf
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.
