[occi-wg] Action description in resources

[Ralf Nyren]

Hi,

Actions can be a bit tricky, we have to distinguish between the following  
two cases:

1. The set of Actions defined for a certain type (e.g. Compute). This  
information is static and presented by the Kind object describing the  
Compute type.
2. Actions currently applicable to a particular instance, e.g. a Compute  
object. This is a subset of (1) and varies over time.

The "actions" JSON-object you see in the Resource/Link presentation refers  
to (2) applicable actions.

 From a pure OCCI Core perspective only the category identifier would  
indeed be necessar. However, for client convenience a link is provided  
which will executed the action if POST'ed to.

Florian, what do you say about reducing the applicable actions list to  
just a JSON-list of category identifiers? The drawback would be that a  
client always must supply a JSON Action payload to invoke an action when  
POST'ing to the resource.

regards, Ralf
