COAR Notify: Un-processable Notification

This pattern is used to indicate that a previously received Notify notification was un-processable for some reason. The reason is given in the summary property.

Properties

`@context`

The @context must include:

`id`

Notify payloads must describe an AS 2.0 activity. The activity has an id which must be a URI, and the use of URN:UUID is recommended. An HTTP URI may be used instead, but in such cases the URI should resolve to a useful resource.

`inReplyTo`

In this particular example: inReplyTo is specified because this is a response to a previous notification. inReplyTo takes the URI (URN:UUID or HTTP URI) which identifies the activity for which this is a response.

`object`

The object describes the resource which is the main focus of this notification.

In this particular example:

An id which is the HTTP URI of the "landing page" for the resource.
A type which should include the value AboutPage from schema.org.
An ietf:cite-as which contains the persistent HTTP URI (sometimes called the "PID") which is to be used to cite or link to the resource.
An ietf:item containing the details of the actual content resource. The ietf:item has:
- An id containing the HTTP URI of the content file for the resource.
- A type describing the content file.
- A mediaType which contains the MIME Type of the content file.

`origin`

The origin describes the system which has sent the notification. The origin has:

An id which is an HTTP URI identifying the sending system
A type which should include the value Service from AS 2.0.
An inbox which is the HTTP URI of the LDN inbox for the origin

`summary`

In this particular example: The summary is used to describe the reason (in plain text) that the request could not be processed.

`target`

The target describes the system which is intended to receive the notification. The target has:

An id which is an HTTP URI identifying the receiving system
A type which should include the value Service from AS 2.0.
An inbox which is the HTTP URI of the LDN inbox for the target

`type`

The activity has a type which should include Flag & coar-notify:UnprocessableNotification
