Gary Mazzaferro and I have created a whitepaper that discusses the coordination going on between two early cloud standards. 
The first is the Open Cloud Computing Interface, or OCCI for short. OCCI is a standard, RESTful interface to control a cloud computing infrastructure in an interoperable manner. It is being developed by the Open Grid Forum (OGF) and early drafts are available on the OCCI Web site.
The second standard is called the Cloud Data Management Interface (CDMI). CDMI in a similar manner allows for the interoperable access to and control of a cloud 
storage infrastructure. CDMI is being developed by the Storage Networking Industry Association. CDMI is also RESTful in design and allows for both a data path and a control path to cloud storage. But CDMI can also be used as the control path for cloud computing storage needs if you couple it with a cloud computing standard such as OCCI.
To learn more about SNIA’s Cloud Data Management
Interface (CDMI) standard, and how it works with Cloud Computing
standards such as the OGF Open Cloud Computing Interface (OCCI) please
