Review minutes

   [8]Feb-10 minutes

      [8] https://www.w3.org/2020/02/10-wot-sec-minutes.html

   McCool: any objections to accept them?

   (no objections)

   McCool: minutes approved

DID review

   McCool: still working on it

   David: there was a session on IoT and DID during the DID
   meeting
   ... shall I paste the link?

   McCool: maybe helpful

   <dezell> DIDs and IoT (from 29 January 2020)

   McCool: (goes through the minutes from the DID f2f meeting)
   ... think IDs may be managed by some distributed system like
   blockchain

   David: a lot of messages there

   McCool: blockchains are not explicitly required but some
   systems expect it
   ... the minutes mention IETF/TCG - Device ID - Impllicit
   Identifier
   ... this is typical for provisioning, etc.

   Kaz: as I mentioned the other day, I also talked with Ivan
   Herman, the DID-WG Team Contact, and we agreed further
   collaboration between WoT and DID would be important
   ... so probably having a joint call would be useful

   McCool: make sense
   ... (updates the WoT Main call wiki with a possible joint call
   with DID)

   [12]WoT Main call wiki

     [12] https://www.w3.org/WoT/IG/wiki/Main_WoT_WebConf

   McCool: having a joint call would be a good idea
   ... Manu Sporny, the main Editor should be also included

   Kaz: happy to contact the DID guys about the possible joint
   call

   McCool: David, do you know if they have any survey documents
   about existing standards, etc.?

   <dezell> [13]https://www.w3.org/2019/did-wg/

     [13] https://www.w3.org/2019/did-wg/

   Kaz: maybe we can look at the references sections of the Use
   cases document and the DID spec document

   McCool: that's true
   ... would see the abstract first
   ... e.g., Thing Description could be related to the
   "resolvable" feature
   ... also section "2.4 Accessing service endpoints"

   [14]2.4 Accessing service endpoints

     [14] https://www.w3.org/TR/did-use-cases/#accessingServiceEndpoints

   McCool: but would see more concrete use cases for IoT purposes

   David: right
   ... that is one of the reasons Sam made a presentation on IoT
   use cases

   McCool: and also "2.5 Identifiers in an ecosystem of verifiable
   credentials (VCs)"

   [15]2.5 Identifiers in an ecosystem of verifiable credentials
   (VCs)

     [15] https://www.w3.org/TR/did-use-cases/#vcEcosystem

   McCool: (looks into the diagram at "3. DID Actions")

   [16]3. DID Actions

     [16] https://www.w3.org/TR/did-use-cases/#actions

   McCool: don't see any "registration" action here

   David: resolution is key point of the decentralized identifiers

   McCool: what if we expect some controller which manages the
   access
   ... there is "ISSUE 14" saying [[What does it mean for a DID to
   be "recorded in a registry"?]]

   [17]did-use-cases Issue 14

     [17] https://github.com/w3c/did-use-cases/issues/14

   McCool: let me capture this issue on my todo list
   ... next "3.3 Authenticate"

   [18]3.3 Authenticate

     [18] https://www.w3.org/TR/did-use-cases/#authenticate

   McCool: prove control typically through some sort of
   challenge-response
   ... need to read through this document
   ... there is also "3.13 Deactivate"
   ... we might want to include it into our lifecycle diagram

   David: some of the DID guys are active on TLS standardizaton
   within IETF

   McCool: can see that
   ... then "4. feature/Benefit Grid"

   [19]4. Feature/Benefit Grid

     [19] https://www.w3.org/TR/did-use-cases/#featureBenefitGrid

   McCool: let's see "7. Focal Use Cases"

   [20]7. Focal Use Cases

     [20] https://www.w3.org/TR/did-use-cases/#focalUseCases

   McCool: (goes through the use cases)
   ... "7.5 Single Sign On" might be relevant for IoT purposes

   [21]7.5 Single Sign On (security)

     [21] https://www.w3.org/TR/did-use-cases/#sso

   McCool: (also look at the "DID Resolution" doc)

   [22]DID Resolution draft

     [22] https://w3c-ccg.github.io/did-resolution/

   McCool: (then visit the references section of the did-core spec
   draft)

   [23]D. References (did-core)

     [23] https://www.w3.org/TR/did-core/#references
