Files implements the following APIs:
Files implements the Atom Syndication Format (Atom 1.0) to serve Atom feeds that you can use in your applications to search for and retrieve files added to a collection by the people in your organization. The format documented here is what feed readers use to discover new or updated files.
Files implements the Atom Publishing Protocol to enable you to manipulate files. Files provides a service document and some category documents. The service document contains the currently authenticated user's collections and feeds. You can use the publishing APIs in your applications to perform actions, such as adding a file to a collection. When interacting with collections to which you have owner access, you can add a file or update and delete any file. When interacting with collections to which you have Author access, you can add a file or update and delete the files that you authored.
