Abstract:
The Event-driven, or Notification-based, interaction pattern is a commonly used pattern
for inter-object communications. Examples exist in many domains, for example in
publish/subscribe systems provided by Message Oriented Middleware vendors, or in
system and device management domains. This notification pattern is increasingly being
used in a Web services context.

WS-Notification is a family of related white papers and specifications that define a
standard Web services approach to notification using a topic-based publish/subscribe
pattern. It includes: standard message exchanges to be implemented by service
providers that wish to participate in Notifications, standard message exchanges for a
notification broker service provider (allowing publication of messages from entities that
are not themselves service providers), operational requirements expected of service
providers and requestors that participate in notifications, and an XML model that
describes topics. The WS-Notification family of documents includes: a white paper:
Publish-Subscribe Notification for Web services as well as three normative specifications:
WS-BaseNotification, WS-BrokeredNotification, and WS-Topics.

This document defines the Web services interfaces for NotificationProducers and
NotificationConsumers. It includes standard message exchanges to be implemented by
service providers that wish to act in these roles, along with operational requirements
expected of them. This is the base specification on which the other WS-Notification
specification documents depend. An implementer interested just in direct, point to point,

1 Introduction
84
85
86
87
The Event-driven, or Notification-based, interaction pattern is a commonly used pattern for interobject communications. Examples exist in many domains, for example in publish/subscribe
systems provided by Message Oriented Middleware vendors, or in system and device
management domains.
88
89
90
91
92
93
The WS-Notification family of specifications defines a standard Web services approach to
notification. This document is the base specification on which all the other specifications in the
family depend. It defines the normative Web services interfaces for two of the important roles in
the notification pattern, namely the NotificationProducer and NotificationConsumer roles. This
specification includes standard message exchanges to be implemented by service providers that
wish to act in these roles, along with operational requirements expected of them.
94
95
96
97
98
A NotificationConsumer can be registered to receive notifications directly from a
NotificationProducer, so an implementer interested just in direct, point to point, notification need
only read this WS-Base Notification specification, together with the additional material that is to
be found in Publish-Subscribe Notification for Web Services document [WS-Notification
Whitepaper].
99
100
101
In the remainder of this section we will give a brief introduction to the Notification pattern, and the
terms we will use in this specification. For a more complete description, the reader is encouraged
to consult [WS-Notification Whitepaper].
102
103
In the Notification pattern a Web service, or other entity, disseminates information to a set of
other Web services, without having to have prior knowledge of these other Web services.
104
105
106
107
108
109
110
111
This specification defines a role called the NotificationProducer. A NotificationProducer accepts
incoming Subscribe requests, each subscribe request identifies one or more Topics of interest
and a reference to a NotificationConsumer. The NotificationProducer maintains a list of
subscriptions (each subscription entry contains the Topic(s), a reference to the
NotificationConsumer and possibly additional information). When it has a notification to distribute,
the NotificationProducer matches the notification against the interest registered in each
Subscription known to it. If it identifies a match it issues the Notification to the
NotificationConsumer associated with that Subscription.
112
113
114
This specification allows the use of a variety of dialects in which to refer to Topics, ranging from
simple QNames, to more sophisticated path-based Expression languages. Topic classifications
and Topic Expressions are discussed more fully in [WS-Topics].
115
116
117
118
The configuration where a NotificationConsumer is subscribed directly to the NotificationProducer
is referred to as the direct or point-to-point notification pattern. There are other variations of the
Notification pattern, where the NotificationConsumer is subscribed to an intermediary
NotificationBroker service. These are covered by the [WS-Brokered Notification] specification.
119
1.1 Goals and Requirements
120
121
122
The overall objectives of WS- Notification are presented in [WS- Notification
Whitepaper]. The specific subset of those objectives realized by WS- BaseNotification
is listed here.
123
124
125
The goal of WS- BaseNotification is to standardize the terminology, concepts,
operations, WSDL and XML needed to express the basic roles involved in Web
services publish and subscribe for notification message exchange.

126
1.1.1 Requirements
127
128
In meeting these goals, the WS- BaseNotification specification must explicitly address
the following requirements:
129
130
131
132
133
Must support resource- constrained devices. The specifications must be
factored in a way that allows resource- constrained devices to participate in the
Notification pattern. Such devices will be able to send information to, and receive
information from Web services, without having to implement all the features of
the specifications.
134
135
136
137
Must provide runtime metadata: There must be a mechanism that lets a
potential Subscriber discover what elements available for subscription are
provided by a NotificationProducer, and in what formats the subscription for
notification can be made.
138
139
In addition, the WS- BaseNotification must allow for the following requirements to be
met
140
141
142
143
WS- BaseNotification must be independent of binding- level details:
Transport protocol details must be orthogonal to the subscription and the delivery
of the notifications, so that the specification can be used over a variety of
different transports.
144
145
146
147
Must allow for Message Oriented Middleware implementations. The design
of the WS- BaseNotification must allow a service that is acting as a
NotificationProducer to delegate its implementation of WS- BaseNotification
semantics to a Message Oriented Middleware provider.
148
149
150
151
152
Relationship to other WS- * specifications: WS- BaseNotification must be
composable with other Web services specifications, in particular WS- Security,
WS- Policy, WS- Federation, WS- Addressing, WS- Coordination, WSResourceProperties, WS- ResourceLifetime, WS- ReliableMessaging [WSReliableMessaging] and the WS- Resource framework [State Paper].
153
1.1.2 Non-Goals
154
The following topics are outside the scope of the WS- BaseNotification specification:
155
156
157
Defining the format of notification payloads: The data carried in
NotificationMessage payloads is application- domain specific, and WSBaseNotification does not prescribe any particular format for this data.
158
159
160
Defining any Events or NotificationMessages. The WS- BaseNotification
specificat ion does not define any st andard or built - in not ificat ion sit uat ions,
events or messages.
161
162
163
164
165
Defining the mapping between Situations and NotificationMessages. The
WS- BaseNotification specification does not define the circumstances under which
a potential producer of information should decide if and when it should actually
notify the registered NotificationConsumers. However they do define how it
performs the notification once it has decided to do so.
166
167
168
Defining the means by which NotificationProducers are discovered by
subscribers It is beyond the scope of this specification to define the mechanisms
for runtime discovery of NotificationProducers.

1.2 Terminology
171
172
173
The keywords "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD",
"SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be
interpreted as described in [RFC 2119].
174
175
176
When describing abstract data models, this specification uses the notational convention used by
the [XML Infoset]. Specifically, abstract property names always appear in square brackets (e.g.,
[some property]).
177
178
179
180
181
When describing concrete XML schemas, this specification uses the notational convention of
[WS-Security]. Specifically, each member of an element s [children] or [attributes] property is
described using an XPath-like notation (e.g., /x:MyHeader/x:SomeProperty/@value1). The use of
{any} indicates the presence of an element wildcard (<xsd:any/>). The use of @{any} indicates
the presence of an attribute wildcard (<xsd:anyAttribute/>).

3 NotificationConsumer Interface
188
189
WS-Notification allows a NotificationProducer to send a NotificationMessage to a
NotificationConsumer in one of two ways:
190
191
1. The NotificationProducer MAY simply send the raw NotificationMessage (i.e. the
application-specific content) to the NotificationConsumer.
192
193
2. The NotificationProducer MAY send the NotificationMessage data using the Notify
message described below
194
195
196
197
198
199
The second option (the Notify message) allows the NotificationProducer to supply additional WSNotification-defined information (such as the Topic) in addition to the application-specific
NotificationMessage content. It also means that the NotificationConsumer can receive a wide
range of NotificationMessages without having to explicitly provide support for each one in its
WSDL. Furthermore, this form of Notification allows a batch of multiple NotificationMessages to
be delivered using a single message.
200
201
202
When a Subscriber sends a Subscribe request message, it indicates which form of Notification is
required (the raw NotificationMessage, or the Notify Message). The NotificationProducer MUST
observe this Subscription parameter, and use the form that has been requested.
203
204
205
206
207
This means that a NotificationConsumer MAY choose to implement the Notify Message, or to
implement raw NotificationMessage(s) explicitly (or both). When requesting creation of a
Subscription on behalf of a NotificationConsumer, a Subscriber SHOULD ensure that the
NotificationConsumer is able to handle the form of Notification it has requested for the given
Subscription.
208
3.1 Notify
209
210
A NotificationProducer MAY send the Notify message to the NotificationConsumer in order to
deliver one or more NotificationMessage(s). The format of the Notify message is:
211
212
213
214
215
216
217
218
219
220
221

<wsnt:Notify>
<wsntw:NotificationMessage>
<wsnt:Topic Dialect= xsd:anyURI >

<wsnt:ProducerReference>?
wsa:EndpointReference
</wsnt:ProducerReference>
<wsnt:Message>xsd:any</wsnt:Message>
<wsnt:NotificationMessage>+
</wsnt:Notify>
224
The components of the Notify message are further described as follows:
225
/wsnt:Notify
226
227
228
229
230
Contains a collection of one or more NotificationMessages to be delivered. This message
MAY follow the implied resource pattern as outlined in [State Paper].
/wsnt:Notify/wsnt:NotificationMessage
Contains a NotificationMessage to be delivered.
/wsnt:Notify/wsnt:NotificationMessage/wsnt:Topic

239
240
241
242
The TopicExpression describing exactly one Topic - the Topic that is associated with this
NotificationMessage. This element describes the topic that matched to a subscription,
causing the NotificationProducer to send the Notify message to the
NotificationConsumer.
/wsnt:Notify/wsnt:NotificationMessage/wsnt:Topic/@Dialect
The dialect used in the TopicExpression. This must be the same dialect used by the
Subscriber when it created the Subscription that yielded this notify message.
/wsnt:Notify/wsnt:NotificationMessage/wsnt:ProducerReference
An OPTIONAL EndpointReference to the NotificationProducer that originally generated
the NotificationMessage artifact.
/wsnt:Notify/wsnt:NotificationMessage/wsnt:Message
A copy of the actual NotificationMessage payload.
243
244
No response is expected from the NotificationConsumer upon receipt of this message.
245

4 NotificationProducer Interface
296
297
298
299
This section describes the message exchanges and resource properties that a
NotificationProducer MUST support. These message exchanges allow the NotificationProducer to
advertise its support for one or more Topics, and allow a Subscriber to create Subscriptions or to
control the delivery of NotificationMessages by the NotificationProducer.
300
4.1 NotificationProducer Resource Properties
301
302
303
304
In addition to the message exchanges described in this specification, a NotificationProducer
MUST also support the required message exchanges defined in the WS-ResourceProperties
specification and MAY support the optional message exchanges defined in the WSResourceProperties specification.
305
306
The Resource Properties document defined by the NotificationProducer MUST include a
reference to the following resource property elements:
307
308
309
310
311
312
313
314
315
316
317
318
319
320
321
322
targetNamespace=
http://docs.oasis-open.org/wsn/2004/06/wsn-WS-BaseNotification-1.2draft-01.xsd
<xsd:element name= Topics type= wsnt:TopicExpressionType
minOccurs= 0 maxOccurs= unbounded />
<xsd:element name= FixedTopicSet type= xsd:boolean
minOccurs= 1 maxOccurs= 1 />
<xsd:element name= TopicExpressionDialects type= xsd:anyURI
minOccurs= 1 maxOccurs= unbounded />
323
These Resource Property elements are further constrained as follows:
324
/wsnt:Topics
325
326
327
328
329
330
331
332
333
This resource property contains collection of Topics supported by the
NotificationProducer. The set of topics is expressed using one or more wsnt:Topic
resource property element(s). Each wsnt:Topic resource property element is a
TopicExpression. The dialect of TopicExpression used can be any dialect. It is
RECOMMENDED to use one of the TopicExpression dialects described in [WS-Topics].
A NotificationProducer MAY use an expression that refers to multiple Topics, if the dialect
used has this capability. The same Topic may be referred to by multiple wsnt:Topic
resource property element(s), for example, in different resource property elements each
using a different dialect.
334
335
336
337
338
If a Topic appears in one of the wsnt:Topic resource property elements, a Subscriber can
reasonably expect the NotificationProducer to deliver NotificationMessages on this Topic.
It is not a guarantee that it will receive any NotificationMessages; the
NotificationProducer may not actually produce any NotificationMessages on the particular
Topic during the time that the Subscriber is registered.

/wsnt:FixedTopicSet
Indicates if the collection of Topics contained within the wsnt:Topic resource property
may change. This value is true if the collection of Topics supported by the
NotificationProducer does not change and false if the NotificationProducer allows the
collection to change (for example if it allows additional Topics to be supported should
publishers or subscribers request them).
/wsnt:TopicExpressionDialects
Indicates one or more TopicExpression dialect(s) that are supported by the
NotificationProducer. If a URI corresponding to a dialect appears in this resource
property, a subscriber is assured that a subscription request containing a valid topic
expression using that dialect will be accepted by the NotificationProducer. The
TopicExpressionDialects property is a fixed property , i.e. its value, for any given
NotificationProducer WS-Resource, does not change over time.
352
4.2 Subscribe
353
354
A Subscriber sends a Subscribe message to a NotificationProducer in order to register the
interest of a NotificationConsumer for NotificationMessages related to one or more Topics.
355
356
357
358
359
360
As part of the processing of a Subscribe request message, the NotificationProducer MUST create
a Subscription resource representing the Subscription. It returns an EndpointReference in the
response to the Subscribe request. This EndpointReference is a WS-Resource-Qualified
EndpointReference as defined in [State Paper] and includes the address of a
SubscriptionManager service and a reference property containing the identity of the Subscription
resource.
361
362
363
Sending two identical Subscribe request messages to a NotificationProducer will result in the
creation of two Subscription resources. The NotificationConsumer will be associated with both
Subscription resources and so will receive two copies of any matching NotificationMessage.
364
The format of the Subscribe message is:
365
366
367
368
369
370
371
372
373
374
375

383
<wsnt:Subscribe>
<wsnt:ConsumerReference>
wsa:endpointReference
</wsnt: ConsumerReference>
<wsnt:TopicExpression Dialect = xsd:anyURI >
{any}
</wsnt:TopicExpression>
<wsnt:UseNotify> xsd:boolean </wsnt:UseNotify>?
<wsnt:Precondition> wsrp:QueryExpression </Precondition>?

<wsnt:SubscriptionPolicy> {any} </wsnt:SubscriptionPolicy>?
<wsnt:InitialTerminationTime>
xsd:dateTime
</wsnt:InitialTerminationTime>?
</wsnt:Subscribe>
This request message MUST follow the implied resource pattern as outlined in [State Paper]. The
components of the Subscribe request message are further described as follows:
wsn-WS-BaseNotification-1[1].2-draft-03.doc
Copyright © OASIS Open 2004. All Rights Reserved.
7/23/2004
Page 12 of 44
384
/wsnt:ConsumerReference
385
386
An endpoint reference element from WS-Addressing [WS-Addressing], used to identify
the NotificationConsumer.
387
388
389
In cases where the value of the wsnt:UseNotify component is true , the Web service
identified by the endpoint reference MUST implement the message exchanges defined
by NotificationConsumer (e.g. the Notify message).
390
/wsnt:ConsumerReference/wsa:ReferenceProperties
391
392
393
The ReferenceProperties MAY contain an identifier of the resource to which the
NotificationMessage should be delivered. This is used in the situation where the
NotificationConsumer itself is implementing the implied resource pattern [State Paper].
394
395
396
397
The ReferenceProperties MAY contain other elements useful in the NotificationMessage
delivery. For example the ReferenceProperties could contain a correlationContext - an
element that is returned as part of each NotificationMessage delivered to the
NotificationConsumer.
398
399
400
401
/wsnt:TopicExpression
A TopicExpression that identifies one or more Topics supported by the
NotificationProducer.
/wsnt:TopicExpression/@Dialect
402
403
404
A URI that identifies the language of the TopicExpression. WS-Topics defines some
standard URIs. Designers MAY define and use other domain-specific URIs to identify the
dialect of the TopicExpression.
405
406
407
The NotificationProducer MAY refuse to process the Subscribe request if the dialect used
by the Subscriber in the TopicExpression is not one of the dialects supported by the
NotificationProducer.
408
/wsnt:UseNotify
409
410
411
A boolean value that indicates how the NotificationProducer is to deliver
NotificationMessages to the NotificationConsumer. This component is optional, if missing
the default value is true .
412
413
414
415
If this value is true then the NoticationProducer MUST use the wsnt:Notify message to
deliver NotificationMessages to the NotificationConsumer. In this case the
NotificationConsumer referred to in the wsnt:ConsumerReference element MUST
implement the Notify message and include a Notify operation in its portType definition.
416
417
418
419
420
If this value is false then the NoticationProducer MUST deliver the NotificationMessage
using the raw NotificationMessage itself. In this case the NotificationConsumer referred to
in the wsnt:ConsumerReference element MUST implement all the NotificationMessages
associated with the Topic or Topics referred to by the TopicExpression, and include
corresponding operations in its portType definition.
421
/wsnt:Precondition
422
This component contains a QueryExpression as defined by WS-ResourceProperties.
423
424
425
This component expresses a NotificationProducer-specific precondition associated with
generation of NotificationMessages by the NotificationProducer. A NotificationProducer
object is free to define the syntax and meaning of this expression
wsn-WS-BaseNotification-1[1].2-draft-03.doc
Copyright © OASIS Open 2004. All Rights Reserved.
7/23/2004
Page 13 of 44
426
Non-normative examples of a possible precondition include:
427
428
429
430
An XPath expression on the Resource Properties of the NotificationProducer that
evaluates to a Boolean. The NotificationProducer must only deliver
NotificationMessages to the NotificationConsumer if this expression evaluates to
true .
431
432
A database query operation to be performed in order to generate a
NotificationMessage, or periodic sequence of NotificationMessages.
433
/wsnt:Selector
434
435
436
437
A QueryExpression as defined by WS-ResourceProperties. A wsnt:Selector expression
MUST evaluates to a Boolean. The evaluation context is NotificationMessage(s) that are
Published on the Topic(s) identified by the TopicPathExpression defined by the
wsnt:TopicPathExpression component of this message.
438
439
The NotificationProducer must only deliver NotificationMessages to the
NotificationConsumer if this expression evaluates to true .
440
/wsnt:SubscriptionPolicy
441
442
443
444
445
446
447
This optional component is an open component intended to be used in an application
specific way to specify policy related requirements/assertions associated with the
subscribe requests. This mechanism could be used to govern the message rate (e.g.
maximum 3 messages per second), reliability of the NotificationMessage delivery, etc.
The semantics of how the NotificationProducer MUST or MAY react to the policy
requirements and assertions appearing in this component are specific to the actual policy
grammar used.
448
449
One non-normative example use of this component is to specify a WS-Policy [WS-Policy]
element indicating the requested policies to apply to the Subscription.
450
451
452
If this component is not specified in the Subscribe request message, then the
NotificationProducer SHOULD use other means (such as directly contacting the
NotificationConsumer) to resolve any policy-related inquiries.
453
/wsnt:InitialTerminationTime
454
455
456
457
458
459
460
461
462
463
This component contains the service requestor s suggestion for the initial termination
time of the Subscription being created. This time is relative to the time source used by the
NotificationProducer. If the NotificationProducer is unable or unwilling to set the
TerminationTime resource property of the Subscription resource to the given value or
greater, then the Subscribe request MUST fault. If the value is not in the future relative
to the current time as known by the NotificationProducer, the Subscribe request MUST
fault. The use of the xsi:nil attribute with value true indicates there is no scheduled
termination time requested for the Subscription. If the element does not include the time
zone designation, the value of the element MUST be interpreted as universal time (UTC)
time.
464
465
If this component is not included, the initial value of the TerminationTime resource
property is dependent on the implementation of the NotificationProducer.
466
467
468
469
The response to the Subscribe request message is a message of the following form:
<wsnt:SubscribeResponse>
<wsnt:SubscriptionReference>

479
The contents of the SubscribeResponse message are further described as follows:
480
/wsnt:SubscriptionReference/wsa:Address
481
482
483
484
485
486
487
The address of a Web service that implements the SubscriptionManager set of
messages. This SubscriptionManager is associated with the Subscription resource
created by the Subscribe message following the implied resource pattern.
/wsnt:SubscriptionReference/wsa:ReferenceProperties
An identifier of the Subscription resource following to the implied resource pattern.
Instead of the SubscribeResponse message, the NotificationProducer may also send the
following faults in response to a Subscribe message:
488
Unable to create subscription
489
TopicPath Dialect not understood
490
Others, TBD

4.3 GetCurrentMessage
584
585
586
587
In response to a GetCurrentMessage message, the NotificationProducer MAY return the last
NotificationMessage published to a given Topic. This is a non-destructive read, and allows a
newly-subscribed NotificationConsumer to get the last NotificationMessage that other
NotificationConsumers have received.
588
589
590
591
592
In certain circumstances, a NotificationProducer MAY choose to not cache the last
NotificationMessage to one or more Topics it supports. In such cases, the NotificationProducer
MUST respond with a fault message indicating that no current message is available on that
Topic. The NotificationProducer MAY choose to communicate its caching policy by some means
not specified in this document, such as using a policy assertion.
593
The format of the GetCurrentMessage request message is:
594
595
596
597
598
<wsnt:GetCurrentMessage>
<wsnt:Topic Dialect= xsd:anyURI >{any}</wsnt:Topic>
</wsnt:GetCurrentMessage>
599
600
This request message MUST follow the implied resource pattern as outlined in [State Paper]. The
components of the GetCurrentMessage request message are further described as follows:
601
/wsnt:Topic
602
603
604
605
606
607
A TopicExpression that identifies exactly one Topic.
The response of the GetCurrentMessage request message is a message of the following form:
<wsnt:GetCurrentMessageResponse>
{any}
</wsnt:GetCurrentMessageResponse>

Contains the last NotificationMessage associated with the Topic identified by the request
message.
Instead of the GetCurrentMessageResponse message, the NotificationProducer may also send
the following faults in response to a GetCurrentMessage message:
615
Invalid TopicExpression
616
617
Given TopicExpression did not match exactly one Topic supported by the
NotificationProducer
618

5 SubscriptionManager Interface
683
684
685
The SubscriptionManager interface defines message exchanges to manipulate Subscription
resources. The SubscriptionManager follows the implied resource pattern as described in [State
Paper].
686
687
688
A SubscriptionManager MUST support the required message exchanges associated with the WSResourceProperties specification [WS-ResourceProperties] and MAY support the optional
message exchanges defined by WS-ResourceProperties.
689
690
691
692
The SubscriptionManager MUST support the message exchanges defined for both forms of
resource lifetime (immediate and scheduled destruction) by WS-ResourceLifetime [WSResourceLifetime]. These message exchanges define the means by which Subscription
resources can be explicitly destroyed, or destroyed using a scheduled (time-based) mechanism.
693
5.1 Subscription Resource Properties
694
695
696
In addition to the Resource Properties required by WS-ResourceLifetime, the Subscription
resource MUST include a reference to each of the following Resource Property elements in its
Resource Properties document:
697
698
699
700
701
702
703
704
705
706
707
708
709
710
711
712

714
715
716
717
718
719
<xsd:element name= ConsumerReference
type= wsa:EndpointReferenceType
minOccurs= 1 maxOccurs= 1 />
<xsd:element name= TopicExpression
type= wsnt:TopicExpressionType
minOccurs= 1 maxOccurs= 1 />
<xsd:element name= UseNotify
type= xsd:boolean
minOccurs= 1 maxOccurs= 1 />
<xsd:element name= Precondition
type= wsrp:QueryExpressionType
minOccurs= 0 maxOccurs= 1 />
<xsd:element name= Selector
type= wsrp:QueryExpressionType
minOccurs= 0 maxOccurs= 1 />
<xsd:element name= SubscriptionPolicy
type= xsd:anyType
minOccurs= 0 maxOccurs= 1 />
<xsd:element name= CreationTime
type= xsd:dateTime
minOccurs= 0 maxOccurs= 1 />
720
These Resource Property elements are further described as follows:
721
722
/wsnt:ConsumerReference and /wsnt:TopicExpression and /wsnt:UseNotify and
/wsnt:Precondition and /wsnt:Selector and /wsnt:SubscriptionPolicy
723
724
725
These elements are as defined in the description of the Subscribe request message (see
4.2).
/wsnt:CreationTime
wsn-WS-BaseNotification-1[1].2-draft-03.doc
Copyright © OASIS Open 2004. All Rights Reserved.

Page 20 of 44
726
727
728
729
730
731
732
Indicates the date and time at which the Subscription was created. This is an optional
component, supporting resource constrained devices which cannot associate a creation
time with subscription resources they create.
If the SubscriptionManager also accepts the SetResourceProperties request message as defined
in WS-ResourceProperties, the following properties MAY be modified by the requestor:
/wsnt:ConsumerReference and /wsnt:TopicExpression and /wsnt:UseNotify and
/wsnt:Precondition and /wsnt:Selector and /wsnt:SubscriptionPolicy
733
5.2 PauseSubscription
734
735
736
To temporarily suspend the delivery of NotificationMessages on the given Subscription, a
requestor MUST send a PauseSubscription request message to the SubscriptionManager. The
PauseSubscription request message has the following form:
737
738
739
<wsnt:PauseSubscription/>
740
This request message MUST follow the implied resource pattern as outlined in [State Paper].
741
742
743
Upon successful processing of this message the Subscription is in the paused state. Delivery of
NotificationMessages can be resumed by sending the ResumeSubscription request message
(see 5.3).
744
745
746
In an asynchronous implementation, there could be some NotificationMessages in-flight at the
time the Subscription was paused. A NotificationProducer MAY attempt to deliver these in-flight
NotificationMessages.
747
748
749
750
Note: transitioning between the paused state and the resumed state has no effect on the
TerminationTime of the Subscription resource [WS-ResourceLifetime]. A Subscription s
TerminationTime may elapse while it is in a paused state, initiating the scheduled destruction of
the Subscription resource.

5.3 ResumeSubscription
813
814
815
If a requestor wishes to resume the delivery of NotificationMessages on the given Subscription, it
must send a ResumeSubscription request message. The ResumeSubscription request message
has the following form:
816
817
818
<wsnt:ResumeSubscription/>
819
820
This request message MUST follow the implied resource pattern as outlined in [State Paper].
Upon successful processing of this message the Subscription is no longer in the paused state.
821
822
If a Subscription is not in the paused state, and it is the subject of a ResumeSubscription request
message, no change occurs.
823
824
825
When a Subscription is resumed the NotificationProducer MAY choose from one of the following
courses of action. The choice MAY be determined by the NotificationProducer itself, or MAY be
specified by a Policy associated with the Subscription.
826
827
828
1. Generate NotificationMessages for all the Situations related to the Subscription that
occurred while the Subscription was paused (as well as for any new Situations that occur
after the Subscription has been resumed).
829
830
831
2. Generate a NotificationMessage for the last Situation that occurred while the Subscription
was paused (as well as for any new situations that occur after the topic has been
resumed).
832
833
3. Generate no NotificationMessages until a Situation occurs after the Subscription has
been resumed.
834
835
If the SubscriptionManager accepts the ResumeSubscription request message, it MUST respond
with a message of the following form:
836
837
838
839
840
<wsnt:ResumeSubscriptionResponse />
Instead of the ResumeSubscriptionResponse message, the SubscriptionManager may also send
the following faults in response to a ResumeSubscription request message:
841
Resume operation could not be performed on the Subscription
