In the video some of the basic operations supported by the OCCI OpenStack implementation are demonstrated.
By having this API exposed out of OpenStack, large projects such as FutureGrid, EGI FedCloud, FIware and CompatibleOne (as well as others some listed here on the OCCI website) can leverage OpenStack as an infrastructure platform and in so growing the OpenStack community and adoption all the more! This also has the backing of recommendations from the UK and German Governments. Details of what it can do can be found in the OpenStack wiki. This is work that has been carried out by Intel Labs Europe in the Cloud Service Lab and is partially funded by FIware and echoes in spirit, as does the OCCI working group's principles those of OpenStack.
