One thing I particularly like about CoAP is the &#x2F;.well-known URI support (<a href="http:&#x2F;&#x2F;tools.ietf.org&#x2F;html&#x2F;rfc7252#section-7" rel="nofollow">http:&#x2F;&#x2F;tools.ietf.org&#x2F;html&#x2F;rfc7252#section-7</a>). It lets you implement services with easily discoverable data endpoints. E.g. IoT sensor devices can be made self-documenting in a lightweight manner.
