  • GFD.184 – OCCI Infrastructure (v1.1) contains the definition of the OCCI Infrastructure extension for the IaaS domain. The document defines additional resource types, their attributes and the actions that can be taken on each resource type. The  specification’s version is 1.1.
  • GFD.185 – OCCI HTTP Rendering (v1.1) defines how to interact with the OCCI Core Model using the RESTful OCCI API. The document defines how the OCCI Core Model can be communicated and thus serialised using the HTTP protocol. The specification’s version is 1.1.
