in the document, described in this report.

I.12 OGF references and associated summaries

[OGF GFD.183] Open Cloud Computing Interface – Core
The OCCI core specification defines the OCCI core model. The OCCI core model can be interacted with
renderings (including associated behaviours) and expanded through extensions.
[OGF GFD.184] – Open Cloud Computing Interface – Infrastructure

OCCI Infrastructure contains the definition of the OCCI Infrastructure extension for the IaaS domain. The
specification defines additional resource types, their attributes and the actions that can be taken on each
resource type.

[OGF GFD.185] – Open Cloud Computing Interface – RESTful HTTP Rendering
The OCCI HTTP rendering defines how to interact with the OCCI core model using the RESTful OCCI API. The
specification defines how the OCCI core model can be communicated and thus serialized using the HTTP
protocol.
[OGF GFD.192] – Web Services Agreement Specification (WS-Agreement)

The web services agreement specification (WS-Agreement), a web services protocol for establishing
agreement between two parties, such as between a service provider and consumer.
