We’ve built our system to be completely “templatized” therefore we don’t bind directly to any tags. In an effort to clean up our tag database, we are curious if there is a way (programmatically or otherwise) to tell which tags are or aren’t being used?. It’s quite a large system, with 200,000+ tags and 600+ views.

I appreciate any recommendations/tips.
