Features

Here you will find some of the new release's highlights. Check out the Change Log for further information on all changes.

Please also pay attention to the Breaking Changes and some Update Instructions.

Core

Batch DELETE of Objects

Multiple objects can be deleted with one request.
>> DELETE /api/dms/objects

CATALOG Service 

The BETA version of a new CATALOG service is offered that allows for the integration of global catalogs in yuuvis® Momentum. It manages catalog objects and provides CRUD (create, read, update, delete) operations on it. Its endpoints are provided in an own API. 
>> CATALOG Service

Rendition Repository

A default rendition repository can be configured. PDF renditions of binary content files assigned to objects can be stored in the default rendition repository. Thus, renditions can be retrieved from storage and are not regenerated for each retrieval request. Whenever a PDF rendition is requested for an object, it is retrieved from the default rendition repository. If available, the stored rendition will be returned. If not available, the requested rendition is generated from the binary content file that is assigned to the object, stored in the default rendition repository and finally returned.
>> REPOSITORY Service

Restructured Commands in COMMANDER Service

The commands available for the COMMANDER service are offered in a new structure.
>> Commands

Export of all Tenant Data (KDDA)

All data stored within a tenant can be exported via COMMANDER service.
>> maintain-export Command

Additional Separator in tenant-specific Type IDs

In every property definition and every object type definition the id attribute is required. It is used to identify the object type or property. Type IDs are also used as the name of the type, e.g., in query operations. Hence, it is recommended to choose meaningful values for type IDs. A prefix separated with a : character allows to identify tenant-specific or app-specific types. For tenant-specific type IDs, it is now possible to use the - character as an additional separator within prefixes.
>> Type IDs

Object Types available for Object Creation (KDDA)

Users may be allowed to create objects only from a limited range of object types as defined via their roles. Thus, in object creation processes managed via a client application, you may want to offer only this range of object types to the logged-in user. A new internal endpoint of the SEARCH service is now available for services running inside the yuuvis® Momentum cluster. The endpoint is not accessible via AUTHENTICATION service and API gateway.
>> GET /search/api/search/dsl/check/{action}

Correction of Invalid Objects via Webhook

The webhook POST dms.request.objects.upsert.database-before can now be used to complete or correct objects that are invalid in the original request body. Each object is still validated before the entry point of the webhook, but a validation exception is thrown after the webhook entry point. Thus, webhooks of this type can be triggered even in case of an invalid object. Those objects contain the corresponding validation errors in their options (see example below). Hence, it is possible to, e.g., add required properties to the original request body subsequently via a webhook. The object validation is performed again after the webhook.
>> POST dms.request.objects.upsert.database-before (Webhook)

Support of newer Database Versions

The following Databases can now be used for yuuvis® Momentum:

• Microsoft SQL Server 2019
• CockroachDB 20.2
• CockroachDB 21.1

>> yuuvis® Momentum Requirements

Tenant Management

Tenant Management API

User Deletion (KDDA)

During the deletion of users, all their stored settings will be deleted as well.
>> DELETE /tenant-management/api/system/tenants/{tenant}

Tenant Deletion (KDDA)

The endpoint for tenant deletion deletes all tenant configurations like schema, role set, forms, localizations, icons and catalogs when deleting a tenant.
>> DELETE /tenant-management/api/system/tenants/{tenant}

Technical User Role in Keycloak (KDDA)

Technical users can be created together with a new tenant. The technical users have the YUUVIS_SERVICE role which is added to Keycloak, but not to yuuvis® Momentum. Users with this role are excluded from the user lists returned by the endpoints GET /tenant-management/api/admin/users and GET /tenant-management/api/system/tenants/{tenant}/users. Thus, in yuuvis® architect, they are not displayed in the user list of their tenant and cannot be edited.
Note: The concept of this feature is under development until further notice.

Endpoints for Identity Management (KDDA)

• The endpoints of the Identity Management Controller (idm-controller) provide an interface for user management within a logged-in user's own tenant. They will replace the user information endpoints of the USERSERVICE.
• The TENANT-MANAGEMENT service can be combined with the new KEYCLOAK-PROXY service in order to connect multiple instances of the identity provider Keycloak.

KEYCLOAK-PROXY Service

Scaling of the Identity Provider (KDDA)

As of yuuvis® Momentum version 2021 Winter, this new service provides a solution to scale the identity management (IDM) for yuuvis® Momentum, including the TENANT-MANAGEMENT service, USERSERVICE and BPM-ENGINE service (these services require Keycloak as IDM provider). A single Keycloak instance supports up to 50 tenants. So in order to manage a number of tenants larger than 50, it is necessary to run multiple Keycloak instances. They can be connected via the KEYCLOAK-PROXY service such that it will be called by the yuuvis® Momentum services instead of one single Keycloak instance. The KEYCLOAK-PROXY service provides the same REST API with respect to realm and user management as a single Keycloak instance which means that existing Keycloak clients do not need code adjustments for its usage. Thus, yuuvis® Momentum can be operated both with a single Keycloak instance, or with a proxy and multiple instances, depending on the total number of tenants to be hosted.
>> KEYCLOAK-PROXY Service

Business Process Management (BPM)

BPM Engine

Retrieval of Finished Processes

The endpoint for the retrieval of all processes of a user is extended in order to retrieve already finished processes in addition to the ongoing processes. A query parameter can be specified to filter out the finished processes and retrieve only ongoing processes or vice versa.
>> GET /bpm-engine/api/processes

Task Delegation

Assignees of tasks can delegate their tasks to other users. Those delegated tasks' metadata is extended by the property delegationState to distinguish them from assigned tasks. The delegated tasks can be resolved by the users to whom they were delegated. Resolved tasks are returned to the assignee that initated the delegation and it is the responsibility of the original assignee to complete the task (i.e., the delegate cannot complete it).
>> Handling of Process Instances and Tasks

Candidate Users and Groups

In order to specify multiple users that should be able to take an action on one specific task, those users can be set as so-called candidate users. It is possible to assign candidate groups as well by specifying a role. Each user with this role will be a candidate user for the corresponding task. All candidate users are allowed to claim the task and thereby assign it to themselves. As soon as the task is assigned to one of them, it will not be available for all other candidate users until the assignee returns it to them. All candidate users are allowed to complete the task without assigning it to themselves when no assignee is specified.
>> Handling of Process Instances and Tasks

Client Services & Client Development

Web-API Gateway

Catalog Values Provided by Custom Microservice

The values for catalogs can be retrieved from a custom microservice specified by URL.
>> Defining Object Types for yuuvis® client

BPM Endpoints

The bpm-controller is extended by the following endpoints providing the new functionality of the BPM Engine:

...

...

Developer Libraries

BPM Integration in Clients (KDDA)

The support of the BMP Engine is extended:

• Task and process details are now displayed in the clients including process-related metadata like history or attachments.
• Processes can be started via start forms.
• Users can delegate tasks to another user who needs to take action on that task.
• Task forms can be configured to display only fields whose values have to be updated.
• In addition to the conventional fields with their values, a general task description can be specified and displayed as a top bar of task forms.
• Candidate users are allowed to claim, edit and give back the corresponding tasks.
• Start forms are provided for starting processes via plug-in actions.
• Task forms are supporting multi-value fields.

Note: In order to provide those new features, the BPM process model follow-up has been updated. Process instances based on the previous version of the follow-up process model are no longer supported. They are displayed without subject and attachments. You can delete those process instances via the client application or via the corresponding Web-API Gateway endpoint.

>> Connection of BPM Engine

Standard Column and Filter Configurations

In order to unify the management of standard configurations, the standard column and filter configurations are now managed via the Web-API Gateway and no longer via the USERSERVICE.

Note: If standard column or filter configurations have already been stored in your system via the USERSERVICE, they need to be imported again via the corresponding Web-API Gateway endpoint.

yuuvis® Momentum client as reference implementation

The new features of the developer libraries are implemented in yuuvis® Momentum client as reference implementation as well.

• BPM Integration
• Management of Standard Column and Filter Configurations via Web-API Gateway

USERSERVICE

The purpose of the USERSERVICE is management of user-specific settings and contents whereas identity management should be organized by the TENANT-MANAGEMENT service. Thus, following endpoints of the USERSERVICE's API are discontinued and will be not be available in version 2022 Spring:

• GET /userservice/api/users
• GET /userservice/api/users/{userId}

Their functionality will be provided by the new endpoints of Tenant Management API.
