2. StratusLab API's Minutes Image Repository Repo API ● Repo is target to VM disk images ● Repo API allows to manage image metadata ● Actual image location as URL ● StratusLab Sites can use images in the Repostiroy ● Integration with OpenNebula Image management open Service Manager TCloud ● Multi-VM service definition ● OVF based ● Convergence with OCCI should be explored OCCI servers HTTPs - REST ● Security (authentication) based in x509 at proxy level ● Based on current OpenNebula implementation ● Debate on storage API (register before use vs direct ● repo reference), needs more discussion ● Errors (those for end-user) should be more ● informative ● OCCI CLI tools may be preserved if useful ● Users identity is preserved (no mapping), VO rules ● may apply OCCI CLI

Some debate around (no consensus): ● Retry functionality, at operation level within the ● driver. ● Specific LOG2USER command (see OCCI notes)
