<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">OS-FLV-EXTRA-DATA: Do you really need a 17 character scope? Your current scope (I assume it’s a derivative of OpenStack Flavor Extra Data) is
really just redundant info, we know it’s extra data for a flavor since we’re talking about the `extra_specs’ table which is used for flavors. I would think something like `disk:qos’ would be sufficient, informative and succinct.<o:p></o:p></span></p>

are limited to a specific scope there is no danger of overlap so no need for a naming convention.<o:p></o:p></span></p>

should be deleted also. Not a major issue but it would avoid surprises where sale `extra_specs’ could be associated with a new flavor that re-used an ID.<o:p></o:p></span></p>

components a key applies to. I’m in favor of adding a new column to the `extra_specs’ table that would explicitly set the scope but an alternative would be to encode the scope into the key itself, something like `TrustedFilter:trust’ to indicate that the
`trust’ key only applies to the `TrustedFilter’ scheduler component. Feel free to chime in on the BZ entry on how to specify the scope, once we decide on how to deal with this I’ll create a patch to handle it.</span><span lang="EN-US"><o:p></o:p></span></p>
