Directories vs search engines in the IoT (devices usually do not link to other devices like Web pages link to other Web pages).

DNS, DNS-SD, RD, etc.

How do you discover that certain operations (e.g., FETCH/PATCH with SenML) are supported

• Out of band info: based on system properties, etc.
• Opportunistic: try and check response code
• CoRE discovery methods: link rels, interfaces, etc.
