When creating new resources, servers can determine a target URI’s type by examining the URI path ending (URI Slash Semantics).
-When a successful PUT or PATCH request creates a resource, the server MUST use the target URI to assign the URI to that resource.
When a successful POST request creates a resource, the server MUST assign a URI to that resource. Servers MAY allow clients to suggest the URI of a resource created through POST, using the HTTP Slug header as defined in [RFC5023].
When a successful POST request creates a resource, the server MUST assign a URI to that resource.
