Picasa Web Albums provides a variety of representations of photo- and album-related data. There are three independent axes for specifying what you want when you request data: visibility, projection, and path/kind. Visibility values let you request data at various levels of sharing. For example, a visibility value of public requests publicly visible data. For a list of values, see Visibility values, below. The default visibility depends on whether the request is authenticated or not. Projection values let you indicate what elements and extensions should appear in the feed you're requesting. For example, a projection value of base indicates that the representation is a basic Atom feed without any extension elements, suitable for display in an Atom reader. You must specify a projection value. Path and kind values let you indicate what type of items you want information about. For example, a path of user/liz and a kind value of tag requests a feed of tags associated with the user whose username is liz. Path and kind values are separate parts of the URI, but they're used together to indicate the item type(s) desired. You must specify a path, but kind is optional; the default kind depends on the path. To request a particular representation, you specify a visibility value, a projection value, and a path and kind in the URI that you send to Picasa Web Albums.
