Clothes are commonly stored in two ways: neatly or haphazardly. Either way meets the ultimate need of "storing" clothes, but one system is more efficient and more useful. Choosing the efficient approach doesn't mean you have to go to the extreme and sort each article of clothing by color or age, but a closet that allows you to organize by seasonal utility might be beneficial. With respect to metadata, the amount of effort expended to organize data in your metadata system (like clothes in your closet) should be determined by what makes sense for you and your users.
