Not unreasonable. But consider: GitHub provides access to git repositories (the data), and git metadata is used to enrich the interactions with the underlying files (by showing the git history, linking commits and such). PornHub provides access to porn films (data) and uses porn metadata (tags, actors, etc) to enrich the user interaction (by providing relevant links and suggestions). Both GitHub and PornHub are services that enrich the underlying content data by using a metadata source.
