Access Authorization and Permissions

A yuuvis® Momentum user has to be authorized to the functionality of the system by assigning roles. For the individual roles, permissions can be set to allow actions on objects restricted by defined conditions where appropriate and the usage of specific endpoints can be controlled.

Basic Use Case Flows

yuuvis® client as reference implementation

yuuvis® client is a reference implementation, browser-based working environment for the daily work with the yuuvis® Momentum system. The client enables the work with documents and metadata (Document Management System) and provides a basis for further modeled business applications.

Overview of all yuuvis® Momentum Services


The requirement of high and thus horizontal scalability as well as high availability is currently best combatted by architectures comprising of distributable small services which can be run in more than one instance. Such architectures offer redundance and pinpoint scalabilityleading, among other advantages, to the wild success of this architectural pattern. This article describes the services yuuvis® Momentum is made of.

Core Services

The services yuuvis® Momentum Core is made of.

yuuvis® Momentum fields a core consisting of a small zoo of cloud-native microservices, which allows for high availability and scalability. The entirety of the core's functions is made available through the API-gateway as core API. Two servicesthree if counting in the API-gateway serve the microservice architecture itself: ADMIN allowing service administration like restarting a service or changing its intended amount of instances, and CONFIG, reading, caching and delivering configuration information to the other services.

Additional Services

Services for functional extension as upper layers on top of the yuuvis® Momentum core system.

The client services offer, in accordance with the layered onion approach, both additional functionality as well as higher-level API functions valuable to client applications. Next to the user and the viewer services, the web-api gateway service is the main service for the client development.
