tl;dr: I don't think ontologies are suitable for Hackage.
I think I agree. For instance, I just uploaded fix-imports and had to decide which categories it is in. It manages imports, which is IDE-like and people looking for IDE-like features might be interested, so IDE. It's concerned with haskell itself, so Haskell. And it's meant to be used with an editor, though it isn't an editor itself, so Editor. It's actually none of those things, but there's no specific category for it, and if there were I think it would be too small to be useful. So I picked things I think people who might be interested in it would be searching for. I don't think a hierarchy would have helped in this case, but tags would be appropriate. Actually, I wound up using the categories like tags. I think we just need better search, e.g. +tag +tag or something.
