[occi-wg] Question about Compute instance action

Agreed. Perhaps as a note I can append "termination of a resource instance is performed using HTTP DELETE (see section x.y.z)"?

Yes, agreed on the non-intuitive part :)



Is it provider specific what happens if you http-delete a running Compute

Using Actions to Create/Delete Resource instances seems to push to usage

of actions a bit to far IMO.
