Collaboration with URL Bookmarks

The URL in the header of your browser is an effective bookmarking link. It is defined to identify the exact place you are in the Talend Data Catalog UI and the exact object.

Permanence of links (support for change)

Indeed, this Object Identifier is also designed to outlive the metadata it is a part of. As new versions of a model are harvested or what would normally be considered identifying information (e.g., Name) are updated, this URL will still take you to that same element you were viewing before, but just with the latest information available.
