What is the difference between URI, URL, and URN?

Re-explain
These are related but distinct concepts:
URI (Uniform Resource Identifier):
- Generic term for any identifier that identifies a resource
- Superset that includes both URLs and URNs
- Example:
mailto:john@example.com
URL (Uniform Resource Locator):
- Type of URI that specifies location and method to access a resource
- Includes protocol, domain, and path
- Example:
https://api.example.com/users/123
URN (Uniform Resource Name):
- Type of URI that identifies a resource by name in a specific namespace
- Location-independent identifier
- Example:
urn:isbn:0451450523
In REST APIs, we primarily work with URLs to locate and access resources over HTTP.
