Code review comment for lp:~justin-fathomdb/nova/justinsb-metadata

I think I'll probably revert the lines that touched the kernel_id & ramdisk_id - I had to put them in there to get this to work, but it probably doesn't really belong in this patch.

I agree that 'metadata', 'key' and 'value' are potentially problematic names. Two issues though: First, there will be metadata for more than just instances - I can either have one table 'item_properties', or I can go with InstanceProperties, VolumeProperties etc and have multiple tables. And second, "properties" may be a bit overloaded already (e.g. the images already has 'properties' in Dan's code snippet!) Although I'd like the special flags (kernel_id, ramdisk_id, zone, image_type, volume_size etc) to just be treated as well-known metadata, I don't see this happening any time soon, so I don't think we can use 'properties'. Maybe 'Tags'? What do you think Jay?
