I have a taxonomy eg. authors. I want to create a custom UI for. I think integrating with a Meta Box together with other post meta will make things easier for the user. Also I think a jQuery UI AutoComplete (Multiple comma separated values) is more appropriate
So I will need to know how I can "update_post_taxonomy". I suppose I will need to
- if taxonomy does not exists
- create it
- if post does not have the taxonomy term
- add it
- remove terms that are not specified by user
I am sure there are functions for this?
