This section of the guide is intended for authorized users with permissions to author alerts and approve for dissemination. The cycle of authoring and issuing an alert has several work flow combinations. These combinations are illustrated as state transitions in the blueprint. In the subsequent sections we discuss the activities of:
- How to CREATE an alert message? The first step when an event of interest is declared as an event that should be notified.
- How to UPDATE an alert message? Execute this step when an alert that was issued needs to be updates with the current status
- How to CANCEL an alert message" Any alert that was issued erroneously must be followed by a message to cancel the previous message
- How to CLEAR an alert message? Issue an ALL CLEAR after the authorities have declared to pose no threat any longer
A typical work flow steps for issuing an alert would be:
- Create a new alert
- Select a template and edit the Alert block
- Edit the Information block
- Define the alerting area; there are two options
- Submit the alert for review
- Approve or Disapprove alert for dissemination
- Update or Cancel the alert
- Issue an All Clear alert once the threat is no longer active or has passed
- A typical CAP message contains the following segments, which must be completed based on the your standard operating producers: Alert, Information, Predefined Areas, Area, Resource Files]
- If you see the pair of square bracket, then those are most probably created following this technique. These are actually the place holders to replaced with event specific actual information.

Import Particular Alert from the URL for Relay
Sometimes it is necessary just to import particular alert from the URL and relay through the system to your audiences. If this is your case, then you are in right place.
- Go to Alerts from the menu. On the left panel, you will see the number of options including Import from Feed URL under ALERTS. Or you can use the URL /eden/cap/alert/import_feed.
- Grab the cap extension URL from an external system. As an example, you can use this CAP URL. Copy and paste in the URL box.
- If the URL access is authenticated, i.e. if it requires username and password, put them respectively in the next boxes.
- While importing, if there is any error, you can neglect those error by checking the Ignore Errors? checkbox.
- This is imported as an external alert in the system. You can relay this alert if you think this is relevant to your audience.
If successful, the system redirects to the newly created alert. You can then Approve or Submit the Alert for Approval depending on your role assigned by your organization.
Authorizing and Approving a CAP Message
Any CAP Message must be authorize before publishing, posting or dissemination. Normally people with 'Alert Editor' role will create the CAP message and then send for approval to the people with 'Alert Approver' role.
After you (people with Alert Editor role) Create a CAP Message , you can see 'Submit for Approval' button at the top. When clicked, it will send Email and SMS to the people with the 'Alert Approver' with a link to approve or reject the message.
The following alerts can be relayed.
- External Message (alert coming from in alert hub) and,
- Internal Message (alert created by other organisation) can be relayed by the CAP Editor from different organisation.
NB: External alert are not disseminated to the subscribers unless those alert are relayed.
Once you open the alerts that can be relayed, you can see a Relay Alert at the top.
Update, Cancel or Error a CAP Message
This process follows the state transition and allowable sequences discussed in the SAMBRO GUI Blueprint for MsgType
- Approved alerts that originated from the same organisation as the current user can be updated, canceled or error the previous alerts.
- An event (like cyclone) can have different speed, direction etc according to time, and for this purpose the previous alert need to be updated to give the current information on the event.
- Or sometimes some parameters may be mistaken in previous alerts which are the error alert and sometime the event may get canceled.
