Resources are the key abstraction in REST. A resource is any information that can be named and addressed. Resources should be:

• Nouns, not verbs: Use /users not /getUsers
• Hierarchical: /users/123/orders/456
• Consistent: Use plural nouns (/users, not /user)
• Meaningful: Clear and descriptive names

Resources represent entities in your domain model and should map to business objects or data entities.
