My only concern is that tags make me think of Twitter. They have prolific tagging but don't use it to form a category system. We already have categories for people, prayer, and stained glass. It seems that you really want a page that lets you view the contents of not just one category, but from multiple categories connected with "and", "or", and "not".

I think it is a perfectly good and noble ambition to strive for "a logically sound ontology as contrasted with a controlled terminology". I just don't believe it is attainable. Perhaps you could build it by including all existing non-compatible ontologies. I had an interesting conversation about tagging last month, in which it was stated that enough tagging could cause new ontologies to appear through organic growth. I find that an interesting concept. Our Wikipedia category tree structures are being built vertically and horizontally around a few main categories like "Category:People" that slowly get split off into subcategories such as "Category:People praying on stained glass windows" as they get too large, whereas a tagging system could lead to the formation of new categories for which there is no parent category (as yet).
