After the connection between projects has been established by the Administrator in the Talend Administration Center, you can launch Talend Studio and open the project where the connection has been established to see all added referenced projects.
All Jobs, Routes and Services part of the added referenced project(s) will by default show under the relevant folder in the Repository tree view, but you can change their display mode to show them as a separate tree. For more information, see How to set the display mode of referenced projects.
Names of the items in the referenced projects look unavailable and are followed by the referenced project name they are part of to distinguish them from item names in the open project.
You can open a read-only copy of the referenced item by simply double clicking it in the tree view.
