The wot-discovery specification covers both how to discover Things and how to offer a directory service as a Thing.

Would be good to make sure the library crate offers both aspects:

• Discovery

  • #4
  • Thing Description collection

• Directory

  • #3
  • Description cache/db
    • Search/Delete/Update

• Use the logic already drafted in libsifis.
• Make the code async instead of blocking.
• Test with the wot-serve advertise example.

The Thing Model specified has the following 1.1 requirements:

• Explicit http protocol binding support
  • htv:methodName, used in the actions, required to signal when PUT, PATCH and friends are used on the same route.
  • htv:statusCodeValue, used in response and additionalResponse
  • htv:headers, used in response to to deliver information in the response http header
• Form::additionalResponse

Depends on sifis-home/wot-td#33

wot-td should make simpler to build the discovery Thing and to consume and wot-serve should make serving the whole thing fairly straightforward.

• #3
• #2
