For example, the bucket name is a string, while a bucket Object Lifecycle Management configuration is an array of rules in which each rule contains several child <code translate="no" dir="ltr">key: value</code> pairs.</p> <p>The mutability of metadata varies:</p> <ul> <li><p>Some you can only view.</p></li> <li><p>Some you can only set when the bucket is first <a href="/storage/docs/creating-buckets">created</a>, and cannot edit or remove.</p></li> <li><p>Some you can add and edit, but not remove.</p></li> <li><p>Some you can add, edit, and remove at any time.</p></li> </ul> <h2 id="non-editable" data-text="Non-editable metadata" tabindex="-1">Non-editable metadata</h2> <p>The following metadata is set during bucket creation, and cannot be edited or removed:</p> <ul> <li><p><a href="/storage/docs/buckets#naming">Bucket name</a></p></li> <li><p><a href="/storage/docs/locations">Bucket location</a></p></li> <li><p>The <a href="/storage/docs/projects">project</a> the bucket is a part of</p></li> <li><p>Generation number</p> <ul> <li><p>A bucket's generation number uniquely identifies the version of the bucket even if more than one version of a bucket share the same name.</p></li> <li><p>A bucket's generation value never changes.</p></li> <li><p>There is no guarantee that generation numbers increase for successive versions, only that each new version has a unique generation number.</p></li> <li><p>There is no relationship between generation numbers of unrelated buckets.</p></li> </ul></li> <li><p>Metageneration number</p> <ul> <li>A bucket's metageneration number uniquely identifies the metadata state of the bucket.
