Keywi (speak Kiwi) is a master-data-management system that allows you to manage and maintain lists of master-data (key-lists). This can be things like "countries of the world", "academic titles", etc. Other applications may use keywi as a microservice to integrate such data and let the user choose values from such a key-list using a combobox. This allows administrators to add new items to a key-list or modify existing items on the fly. The apps using keywi will then (potentially after a small delay) reflect this changes without the need to update the software or restart any app. The keywi server (backend) is written in Java based on devon4j and the client (frontend) is written in TypeScript based on devon4ng (using Angular).
