Editing Object Metadata

Each object in Amazon S3 has a set of key-value pairs that represents its metadata. There are two types of metadata:

  • System metadata – Sometimes processed by Amazon S3, e.g., Content-Type, and Content-Length.

  • User metadata – Never processed by Amazon S3.

    User metadata is stored with the object and returned with it.

The maximum size for user metadata is 2 KB, and both the keys and their values must conform to US-ASCII standards.

This section explains how to use the console to add and remove the metadata associated with an object.
