The 
Subscribe to WSDM Resource 
assertion allows you to send subscription requests to a specified resource that is interoperable with the Department of Defence Joint Web Services Distributed Management (WSDM) Specification. This assertion is automatically added to a policy when the WSDM Subscription internal service is published. This assertion recognizes the methods: 
Subscribe, Renew, Unsubscribe
.
You can optionally specify an outbound policy if you wish to apply a security policy and/or provide access to the trust store for outbound messages. Eligible outbound policies are those of type "Internal Use Policy", with the tag "WSDM-notification". For more information, see Create a Policy or Policy Fragment.
WSDM subscription notifications can be enabled or disabled using the WSDM.notification.enabled cluster property.
The following are some technical limitations to subscribing to an WSDM resource:
  • IRIs are not specifically supported and validations are not performed.
  • SOAP and WSA namespaces are not accepted in endpoint reference parameters.
  • Endpoint reference parameters are limited to 16KB.
Using the Assertion
  1. This assertion is automatically added to a policy when you publish an WSDM Subscription internal service. You can also manually add it to a policy if it has been deleted; see Add an Assertion.
  2. Select an outbound policy to be applied to notification messages. If an outbound policy is not required, select "
    <no notification policy>
    " and the notification will be routed to the subscriber without further processing. To add policies to this list, create a policy of type 
    "Internal Use Policy"
    , with the tag 
    "WSDM-notification"
    .
    If you change notification policies, this will be applied only to new subscriptions. To update existing subscriptions to use the new policy, you must send a "Renew" message to renew the existing subscriptions. If a policy used by the Subscribe to WSDM Resource assertion is deleted, you must select another policy to use, otherwise the assertion will fail at runtime. Be sure to send a "Renew" message to existing subscriptions after selecting a new policy.

    when done.
  4. When manually adding the assertion, the 
    WSDM Subscription Properties
     automatically appear. You can also access the properties by right-clicking the assertion in the policy window and selecting 
    WSDM Subscription Properties
     or double-click the assertion in the policy window.
  5. Select an outbound policy to be applied to notification messages. If an outbound policy is not required, select "
    <no notification policy>
    " and the notification will be routed to the subscriber without further processing. To add policies to this list, create a policy of type 
    "Internal Use Policy"
    , with the tag 
    "WSDM-notification"
    .
    If you change notification policies, this will be applied only to new subscriptions. To update existing subscriptions to use the new policy, you must send a "Renew" message to renew the existing subscriptions. If a policy used by the Subscribe to WSDM Resource assertion is deleted, you must select another policy to use, otherwise the assertion will fail at runtime. Be sure to send a "Renew" message to existing subscriptions after selecting a new policy.
