I'd be interested to hear how people currently implement updates to their various OCCI resources. Currently in the spec, it says to perform a PUT and supply _only_ the attributes that need to be updated. This works and is clear in changing or adding items such as attributes or mixins. However what is not so clear to me is how to handle an update that removes a mixin from an existing resource (e.g. I want to remove IP networking capabilities). One solution I suggest would be that the section on updating a resource allow for updating using both POST and PUT. In this case POST can modify (i.e. replace) a _part_ of the resource e.g. a particular attribute. PUT can replace the whole resource _representation_ and in doing so support the removal of items like mixins. Comments?
