This new schema proposal looks really good.
I think we need to ensure we expose two levels of API.
A low level api that works directly with these individual tables should be
provided to allow plugins that extend it to add new taxonomies types
without needing to interact with the db directly.
We can then write the tag/catgeory/link_category API on top of this low
level API so that they do not require any direct db access.
