Hi @owen – appreciate your attention to this. I’ve also suggested that this info could live in a separate app, though I don’t have full UX or product context.
From my perspective, the key abstractions are projects, portfolios (which group related projects of an application), and spaces. I believe this data should be at least visible in both the project catalog and portfolio overview, enabling 1) platform admins to federate these tasks, and 2) app owners to manage it more effectively (see example below).
While the project catalog can feel cluttered, there’s space in the sidebar for a dedicated tab, which could keep things clean. As for the amount of information, one could introduce pagination. The Data lineage doesn’t render more than 500 items at once. One needs to expand it. The same principle could be applied to show all resources in case there are that many.
