Names can also be difficult if not done correctly / uniformly. For instance, "Category Name", "CategoryName", "category_name", and "category-name" can all return differently through search.

I don't think the key is names vs. numbers vs. whatever else, I think it's more important to pick a system that works for the use case, then define / document / communicate it as wide and loud as possible.
