uniqueness over space and time and are computationally difficult to guess. They are globally unique identifiers which can be locally generated without contacting a global registration authority. UUIDs are intended as unique identifiers for both mass tagging objects with an extremely short lifetime and to reliably identifying very persistent objects across a network.

When you PUT an object in a versioning-enabled bucket, the noncurrent version is not overwritten. The following figure shows that...

	replReadyCheck, err := parseBoolHeader(bucket, object, r.Header, xhttp.MinIOCheckDMReplicationReady)
	if err != nil {
		return opts, err
	}
	opts.CheckDMReplicationReady = replReadyCheck

	opts.Tagging = r.Header.Get(xhttp.AmzTagDirective) == accessDirective
	opts.Versioned = globalBucketVersioningSys.PrefixEnabled(bucket, object)
	opts.VersionSuspended = globalBucketVersioningSys.PrefixSuspended(bucket, object)
