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).
