The present standard specifies Interoperability Test Descriptions (TDs) for OCCI and CDMI standards. The Test Descriptions cover the OCCI and CDMI protocol specifications where relevant and more specifically: 

1) OCCI interoperability testing, to prove that end-to-end functionality is as required by the standard. 

2) CDMI interoperability testing, to prove that end-to-end functionality is as required by the standard. 

3) OCCI + CDMI interworking testing, to prove that end-to-end functionality is as required by the standards.
