A flattened many-to-many seems heavy to just associate string values. A good example would be a Contact entity where you maybe have a set of keywords like:

Thanks Kieren. I'm successfully giving ERTag a test drive. It seems to work pretty well. In general it appears it kinda uses the approach I was trying to avoid myself - many-to-many relationship. I know there's much smarter goodies in there though. :-)

On the UI side I would like to use checkboxes to select which categories to apply to an EO. Then, in the database have only those selections saved to the database.
