I chose not to use this, since I've added metadata to the forms generated from the html templates. This allows me to store defaults, entry type types (ie. selects, input, checkboxes, textarea), etc. directly in another metadata table that users can then configure. It adds more configurability to my app (Open Admin) without having to mess with the templates (for which I don't have any web based tools yet). >> However, filesystems are highly optimized storage spaces.

Our differences here are simply one of philosophy. Both approaches (files in filesystems vs fields in database) will work. We agree to disagree... (grin) Thanks for the insights.
