6.3. What is meant by "shared content" – project -> unit or journey?

"Shared content" means that content stored there can be considered "original." Links to this original content can be created in the folder structures; otherwise, they are not visible to the end user. The project can therefore be integrated into the folder structure as often as desired. If the "original" is edited and saved under "Shared Content," the linked projects are also edited. Shared content can only be deleted on the server with the appropriate authorization, as individual authors cannot know whether other authors are also using the content.
