Authentication against the Core API

This article details the authentication methods compatible with the yuuvis® Core API and how to choose the correct one for your use case.

Schema - Defining Object Types

Detailing the available schema, object type definitions as well as property definitions.

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.

Search Query Language

How to query in an SQL-like manner.

Object Representation Formats

A description of the structure in which yuuvis® Momentum expects objects to be formatted and returns objects.

Binary Content Files

Binary content files can be imported and assigned to document objects in yuuvis® Momentum. Archiving can be managed and renditions can be retrieved.

Document Lifecycle Management (DLM)

This article gives information on tagging and schema flow functionality (secondary object types) in the context of a document's lifecycle.

Document Retention

Retentions can be used to ensure that object or document contents are not deleted or changed by setting a proper expiration date.

Apps

Management of apps that are based on yuuvis® Momentum via schema, permissions and availability configurations.

Error Handling

Structure and identification codes of errors that can be thrown during different processes.

System Hooks

Define additional actions triggered by specified events, extend the functionality of yuuvis® Momentum API.

Interceptors

Intervening a running process at a certain position and redirecting the process flow in order to include project-specific processing steps.

Login to the Core API (Java)

This tutorial will give you a brief overview of the most important login procedures for the yuuvis® API system and how to use them in a Java Client application

Importing Documents via Core API

This tutorial shows how documents can be imported into a yuuvis® API system via the Core API. During this tutorial, a short Java application will be developed that implements the HTTP requests for importing documents. We additionally provide a JavaScript version of this tutorial. 

Retrieving Documents via Core API

In this tutorial, we will discuss various ways to retrieve objects via the Core API from the yuuvis® API system using an OkHttp3 Java client.

Updating Documents via Core API

This tutorial demonstrates how to update documents in yuuvis® API with the Core API. The following example will result in a short Java application that implements the HTTP requests for updating a document. 

Deleting Documents via Core API

This tutorial explains how documents can be deleted using the Core API with the help of a Java client. This tutorial requires basic knowledge of importing documents using the Core API.

Retrieving Document History Entries

This tutorial shows how we can use a Java application to make a request to the Core API of the yuuvis® API system to retrieve the history entries of a DMS document. In addition, it briefly describes which history entries are generated for a document.

Compound Documents

Concatenate multiple binary content files as byte arrays in one compound document. Create sub-documents that refer to specified ranges within the total byte array.

Managing the Schema

This tutorial shows how to use the Core API to get the tenant-specific schema of the system, how to validate a schema, and how to bring in a new schema.

Changing Schema Structures ("Schema Flow")

This tutorial shows how to change your basic schema for individual instances of an object type during the entire lifecycle of a document. Classify objects at a later point in time, add or remove property groups at runtime by defining and referencing "floating" secondary object types.

Tagging Objects for Processing

Based on tags, you set up complex stateful processing chains. This tutorial describes how tags can be added, displayed, and updated in an example context. For this purpose, a typical application will be discussed: An import management system, which is an example for a processing chain, where tags are a helpful tool to describe the current status of each object.

Setting and Querying Structured Data

This example tutorial provides explanations and code examples to get an idea on how to define and specify structured data properties and on how to query them.

Overwriting the 'required' Property Attribute

This tutorial shows how to reference the same property definition in different object type definitions, in some of them as a required property and in others as a non-required property.

Preprocessing Metadata using Webhooks

An example Webhook consumer service set up using Java and Spring Boot. 

Interceptor Example Tutorial

Learn how to set up a Microservice that can fill the role of an interceptor of any of the available interceptor types. Java code examples of such microservices can also be found here. 

Importing Documents (JavaScript)

This tutorial shows how documents can be imported into a yuuvis® API system via the Core API. This tutorial is an extension of the Java import tutorial, applying its concepts to a different popular programming language, JavaScript.
