Use Case: As a Platform Operator, I want to group related Building Blocks (BBs) together using tags (e.g., from the tagging catalog) so that Application Teams can easily discover "sets" of services that belong to a specific platform offering. Example: I create an IDP with services K8s namespace, git repo, container registry and database -> they are designed to work together (but not necessarily dependent). I would tag them with "K8s IDP" and if I could switch on that filter in the marketplace (best via URL to also share it), I could point users to my specific platform BBs. It would be a first step towards the "Platform view" suggested elsewhere. Value Created: Improved Discoverability: Prevents specialized BBs from getting "lost" in a crowded marketplace. Enhanced Sales/Demo UX: Allows meshies and customers to demo a cohesive platform experience from the Developer Portal perspective rather than just the Platform Builder. Logical Organization: Aligns the marketplace view with the organization's existing tagging and governance structures.
