A client application is provided with a view of a subset of objects within an object store. A REST protocol, REST interface, or API may be used to access the objects. A coupling server may include a filter and a generator. The generator may automatically generate object metadata for newly created files that matches a filter. A client application may mount a drive on a computer based on metadata objects, such as providing a filter on object metadata to view files a user wants to access; or editing, reading, and updating object metadata as a file.
