12:15:02 <cris> topic: quick updates
12:15:14 <cris> subtopic: signatures
12:15:24 <kaz> s/use case/TD/
12:15:32 <cris> mc: I did some work on signatures for TDs
12:15:46 <kaz> s/publish these/publish them/
12:15:48 <cris> ... it seems that the only candidate is xml Signatures
12:16:01 <cris> ... the only problem is that they are xml not json
12:16:15 <kaz> i|minor pro|-> https://www.w3.org/2021/05/12-wot-minutes.html May-12|
12:16:27 <cris> ... my plan is to get inspired from them and report the same machanism to json
12:17:31 <cris> ... about hashing and singing algorithms we'll pick two to cover requirements from different countries
12:18:26 <cris> ... we need the ability to canonicolize TD fragments or Partial TD to be enable signing
12:19:10 <cris> ... an alternative is to use json pointers instead of canonicalize TD fragments
12:19:28 <cris> ... anyhow I am close to a final PR about signing
12:19:59 <cris> ... the overall plan is to have a signature block and support different signing solutions
12:20:25 <cris> ... for example we can support LDS in the future
12:21:04 <cris> ... any comments?
12:21:19 <cris> subtopic: smart cites workshop
12:21:25 <cris> mc: the dealine is now over
12:21:34 <cris> s/dealine/deadline/
12:21:55 <cris> ... we still need more cites
12:22:18 <cris> kaz: yeah
12:22:33 <cris> mc: did we get a proposal from singapore?
12:22:38 <cris> kaz: not yet
12:22:58 <mjk> If we are planning to use a list (array) of JSON pointers to select TD elements for signing, the list can be used to order the TD. A list containing all of the TD elements would help to canonicalize the TD.
12:23:11 <cris> mc: we got a good coverage of standards and frameworks, the only thing left is more coverage for cites
