Last November, S3 introduced a new set of APIs for Object Tagging[1], which are simply key value metadata associated with objects, this however doesn't seem to be an API wrapped around the already existing x-amz-meta-* tags[2]. Also, beyond an API to GET/PUT/POST tags, S3 also seems to have support for tags in their LifeCycle, ACL and CloudWatch Metrics. Would such an API make sense for RGW? I'd imagine implementing the API itself wouldn't be that difficult and would fit similar to the way we handle object metadata & ACLs etc currently. Adding this to elasticsearch might be interesting, but supporting this in ACLs & LifeCycle might require much more work. Thoughts?
