Yeah, and it also has a different data model. For example:

- each object is required to have a unique fixed-length key, in
addition to the object name
- containers are multi-level, not just flat buckets
- etc

There seem to be some open source CDMI servers out there:

Proxy CDMI to e.g. S3: https://github.com/livenson/vcdm
(it seems like one could run that in front of radosgw)

Serves a local filesystem as CDMI: https://github.com/koenbollen/cdmi-serve

Compliance tests?: https://github.com/livenson/ocmi-tester

Erlang proof-of-concept: https://github.com/jeastman/crime
