Dear all, I have update the Core document to include the changes discussed on the last few confcalls. The LaTeX changes are available from the core-errata branch in the occi-wg Git repository. Please find a compiled document attached. Add a Attribute type to the Core Model -------------------------------------- Many who have implemented the OCCI Core model already added an Attribute type. This change formalise the notion of "attribute properties". Instead of just saying an attribute have a name, an attribute now has its on Attribute type with both name an properties. The new Attribute type is an *identifier* for resource attributes. It does not contain the attribute value. I.e. just as before. A distinction has been added between "client discoverable attributes" (called OCCI Attributes) and attributes internal to the model (called model attributes). occi.core.id, occi.core.source and occi.core.target have been changed back to the model attributes they were until shortly before HTTP Rendering was released. These are determined to be model attributes and thus receive special care in renderings. Change Action to inherit Category --------------------------------- The concept of Action representing the "invocable operation" itself is removed. Instead an Action is just an *identifier* of the operation. An Action instance identifies an invocable operation in much the same way as a Kind instance identifies an Entity sub-type. Impact on the existing HTTP Rendering (occi/1.1) is none. In fact the text/ renderings already use "type=action" in its Category headers. regards, Ralf
