For the kind of supported data, one looks at the README and it supports a lot of different kinds of metadata, hence the generic description. A jpeg (or other image) metadata editor cannot edit metadata for geospatial surveys for example. But this application can. And manage it like any other CRUD application works. By providing users a way to enter a new entry, edit it, remove it, query it, all kinds of things really.
I don’t mean to be rude but this is like the most generic description possible. What kind of data? What kind of metadata? “Manage” it how?
