How should nested resources be used in URLs?

✓Correct answer: For clear ownership one level deep, e.g. /users/42/orders; avoid deep chains like /a/1/b/2/c/3/d
2Always nest as deep as the data model goes
3Never use nesting

Deep nesting makes URLs long and forces clients to know the whole hierarchy. Items with their own IDs can also be accessed at the top level.
