Introduction

By chunking up the system into microservices it can be tough to keep the overview of all available services, their relationships and dependencies to each other. The following graphical overview of our microservice architecture offers you a first entry point into the yuuvis® Momentum landscape. By providing further and more detailed examples based on special use cases (flows) you'll get a better and easy way of understanding our entire landscape.

Graphical Overview

For visualizing the topology of our microservices the following overview shows - on a higher level - many of our core microservices. 
For understanding various flows - on a more granular level - check out the detailed diagrams visualizing special use case. 

Login to the Core API - Authentication (Browser / Application)

...

To interact with yuuvis® it is necessary to log in with a user account. The user accounts are managed by at least one external identity provider.

...

1. - HTTP request to any API endpoint, sending basic authentication or bearer token

2. - verify credentials externally

3. - receive auth code to authentication with auth code

4. - request roleset acquisition

5. - query user roleset externally

6. - receive user roleset

7. - present roleset

8. - provide authentication token and proceed with initial API request

9. - request information from other parts of the system

10. - obtain requested information

11. - produce API response

12. - send HTTP response to user

Note
The authentication flow is always part of all described flows. It is used to get a valid authentication token for further processing.

To interact with yuuvis® Momentum, it is necessary to log in with a user account. The user accounts are managed by at least one external identity provider.

Importing Documents

Documents can be imported into a yuuvis® Momentum system using the provided core API's HTTP requests for importing documents (POST /api/dms/objects). 
>> >> Example Tutorial: Importing Documents via Core API

Retrieval of Content by ID / Older Version

1. - HTTP Post request containing metadata and content

2. - enrichment of request with authentication token

3. - defer content to storage services

3.1 - analyze content file

3.2 - skip content analyzer

4. - content storage handling

4.1 - using custom storage via archive service

4.2 - using s3 interface of repository

5. - create metadata based on previous steps

6. - write metadata to storage / index instances

7. - index new object in ES

8. - create initial audit entry

9. - create API response from metadata

10. - return metadata as HTTP response

During asynchronous import operations, the controller service provides messaging for the boxed in services

Webhook entry points

*1 - dms.request.import.storage.before

The content of already imported documents into the yuuvis® Momentum system can be retrieved using the provided core API's HTTP requests for retrieving content files (GET /api/dms/objects/{objectId}/contents/file). If a specific version of the document's content is to be requested, the endpoint to be called changes and includes the specific version (GET /api/dms/objects/{objectId}/versions/{versionNr}/contents/file). 
>> >> Example Tutorial: Retrieving Documents via Core API

Retrieval of Metadata by ID / Older Version

1. - HTTP get request to object URL

2. - Enrichment of request with authentication Token

3. - Check for User Authorization using search service query

4. - Query elastic search for object ID

5. - Elasticsearch metadata reponse (if user is authorized)

6. - Repository url of objectId

7. - Request content of objectID

8. - Query objectId in Storage Provider

9. - Storage Provider metadata response

10. - Return metadata object metadata

11. - Write CONTENT_ACCESSED audit entry

12. - Create API response from metadata

13. - Return HTTP metadata response
