Open Notificaties is based on the reference implementation of the "API's voor Zaakgericht werken" made by VNG Realisatie. The overall architecture remains faithful to the Common Ground principles and all API specifications.
The architecture of Open Notificaties focusses on excellent performance, optimal stability and to guarantee data integrity. Under the hood, it uses RabbitMQ as message broker with just a light weight REST API on top of it.
It largely resembles the original reference implementation and remains its own component to scale separately from any other component.
