This core service manages schemata, role sets and app sets. Find here characteristics and configuration options.

Characteristics

Function

Schemata and role sets are important customizable configuration files. While role sets define access permissions, schemata define properties and object types that can be global, tenant- or app-specific. As of version 2021 Summer, the tenant-specific app sets define the availability of the different apps for each tenant.

The SYSTEM service treats calls of the public GET and POST endpoints for managing those configuration files. Any update of an active role set, app set or schema is communicated with other services that require this information. The behavior of the SYSTEM service can partially be configured according to the customer's needs.

The following endpoints provided by the API gateway are forwarded to the SYSTEM service.

Schema and Role Set Management

Those endpoints deal with either global, tenant-specific or app-specific definitions of a role set or schema. The GET endpoints return the corresponding active configurations. The POST.../validation endpoints check whether a user-definded file is a valid configuration for the corresponding purpose. Also, the POST endpoints without /validation check whether the passed file is valid for the corresponding purpose. If valid, the new configuration is activated replacing the previous one. If invalid, an error will be thrown and the current configuration stays active.

App Set Management

As of version 2021 Summer, the availability of an app for a specified tenant is managed in an app set via the following endpoints:

• GET /api/system/tenants/{tenant}/apps
• POST /api/system/tenants/{tenant}/apps
• POST /api/system/tenants/{tenant}/apps/validate

Configuration

The yuuvis® Momentum configuration files for the operation in the Kubernetes cluster are stored on the Git Server configured in the system. In order to change the configuration of a service, you need to access the Git repository. 

Note: The schema.xml, roleset.xml and apps.xml files are stored via the configuration service (CONFIG). Thus, they are also saved in Git. In contrast to the service configuration files, these files (schema, role set etc.) should only be changed using the yuuvis® Momentum API.
