Hi, Reading the updated spec on Http Header Rendering [1] I see you have changed the way attributes are represented in the HTTP header. In the latest docbook spec OCCI resource attributes are specified using the "Attribute" header, e.g.: GET /compute/xxx HTTP/1.0 HTTP/1.0 200 OK Attribute: occi.compute.speed=2.0 Attribute: occi.compute.memory=1.0 In the latest spec however it would look like this instead: HTTP/1.0 200 OK occi.compute.speed: 2.0 occi.compute.memory: 1.0 What is the motivation behind this change? I believe the Attribute header is a much more clean approach since it does not pollute the HTTP header namespace with (perhaps) arbitrary names (you have to consider vendor extensions as well). regards, Ralf [1] http://forge.ogf.org/sf/wiki/do/viewPage/projects.occi-wg/wiki/HTTPHeaderRen...
