[occi-wg] Action description in resources

[Mon SPAM]

Hello,
I came to find that Action description inside a Resource / Link 
description get this format :
=======================================================
"actions": [
{
"title": "Disable networkinterface",
"href": "/networkinterface/22fe83ae-a20f-54fc-b436-cec85c94c5e8?action=up",
"category": "http: 
//schemas.ogf.org/occi/infrastructure/networkinterface/action#
}
=======================================================

And i don't understand what's the point of that !
Can someone help me clear this up ?

One more question : what do you mean by "HTTP Links" ?
