Not for certain but in the hopper to think about:
On demand ad-hoc notification case 3466 for specific object only
not sure how to handle that, but it's a very intruiging idea, maybe it's a v.next one though?
or maybe the tags thing will handle this?
CUSTOMER NOTIFICATIONS AND CHANGES
A bcc field for all customer notification subscriptions per case 3398
SCRATCHPAD IDEAS

OVERVIEW
General
thinking of reforming it, making all notifications very short since user can go to directly view data online anyway now, why have an overly time consuming system to format and shit
i.e. no notification more than an SMS (160 characters but will accept more and split them up to 1600) tweet in length (280 characters)
In cases where user wants to send an attachment / report / wiki that's another thing entirely but the message is still super short
All notifications can be optionally filtered IN or OUT via tags on notification related object. I.E. a workorder status change can be ignored or only see if it's tagged "region-new-york" etc
UI
Subscribe from the object itself's menu rather than centralized subscription setup (new)
Admin can still subscribe users on their behalf (new)
SYSTEM
-=-=-=-=-=-=-=-=-=-
Internal workings:
One enum list of NotificationType for any possible notification that can be processed
Notify type is divided by actual type and then by actual delivery method
No delivery schedule anymore, let user decide how to handle at their device end, not our concern, just deliver immediately always
Notify BEfore shoudl support multiple time frames, not just one
Users not involved should not be notified, have choice on that`
e.g. if a user is not booked on a workorder and is just a lowly tech they don't care about other workorder status changes
Types of notifications sitting in delivery queue:
Deliver if something not changed before date "DEADMAN SWITCH"
upon change that negates it from source object it removes the event as no longer required
Deliver immediately regardless
easy peasy
DELIVERY TYPES
Email
UI
(previusly was ayanova memo, but, that's toast now, removing it)
DELIVERY FORMAT
Custom templates for each notification set up centrally?
Hypothetical sequence of operations for designing raven notification and tie into jobs and processor
WidgetStatusChange notification
- OnChange event triggered in [WIDGETBIZ] with before and after state of widget in question (immediately after save or delete or whatever is of interest)
- OnChange processor See if any users are subscribed to this event [CENTRAL_NOTIFICATION_CLASS THIS MUST BE SUPER EFFICIENT AS IT WILL BE HAMMERED]
(events of interest / core central event bus handler of some kind??)
- CENTRAL_NOTIFICATION_CLASS event of interest should cache in memory events of interest and trigger cache invalidation by [EVENT_OF_INTEREST_CLASS] subscription change
- If no then bail out early
- If yes then compares the before and after state of the widget and the given list of events of interest and processes notifications in turn
- Create a notification event in a table of pending notification events [CENTRAL_NOTIFICATION_CLASS]
- See v7 schema for ideas
Deliver notifications
- Job triggers and HandleJob is called on [CENTRAL_NOTIFICATION_CLASS] which in turn checks if any events ready to Deliver
- Hands off NOTIFY_EVENT to deliver one at a time to a [NOTIFICATION_DELIVERY_CLASS] which in turn calls each [NOTIFICATION_DELIVERY_DELIVERY_TYPE-SMPT/POPUP/WHATEVER]
Maintenance
- [CoreJobNotificationSweeper class] maintains the notifications tables see generator spec for thoughts
MISC
=-=-
- NOTIFICATION SUBSCRIPTIONS
- NOTIFICATION DELIVERIES (user or all if manager account)
- What is "Slack"?
- should we tie into it for notifications?
