Objects
Each Amazon S3 object has data, a key, and metadata.
Key
The object key uniquely identifies the object in a bucket.
Metadata
The object metadata is a set of key/value pairs. After the object was uploaded, the object metadata cannot be modified. The only way to modify the metadata is to make a copy of the object and set the metadata.
