Where does OS X store tags list? + Can you edit it to create a batch of new tags?

Does anyone know where OS X stores the full list of available tags (i.e., the list of tags you see under "All tags..." in Finder)? I'm hoping there is a file somewhere with a simple list of tags. I'd like to keep track of the tags I've created so I can remember them when it comes time tag a new file.

On a related note, is there an easy way to create a batch of new tags? I'm thinking that if tags are stored in a list somewhere, perhaps I could edit the list to create new tags. For instance, say I'd like to create 50 new tags? Is there a way to create them quickly--or am I stuck creating them one by one?

Thanks for your help!
