Andrew Nacin has written a thorough post discussing many of the challenges for implementing taxonomy metadata in WordPress core and a potential roadmap for doing so. He also highlights how we may be able to achieve post to post relationships with alterations to the database schema. No promises are offered, but he assures that if this moves forward, it would take many releases to do so. It’s great to see the core team’s thought processes for such challenges in the form of a blog post.
