Meeting minutes

  agenda review

   <kaz> [22]Agenda for today

     [22] https://www.w3.org/WoT/IG/wiki/WG_WoT_Thing_Description_WebConf#May_5.2C_2021

   Sebastian: focus on review of PRs and prepare for final
   document review

   McCool: issue #940, question around signing

  minutes review from last meeting

   <kaz> [23]Apr-28

     [23] https://www.w3.org/2021/04/28-wot-td-minutes.html

   Sebastian: walking through the PRs that we reviewed last week

   Sebastian: we decided to allow as much of JSON schema as we
   can, and include the missing terms

   McCool: there were also some arbitrary extension points that we
   íK we should not allow extensions because it prevents good
   checking for typos

   Sebastian: discussion on selection where multiple forms are
   íK discussion on URI variables
   íK PR for tmRequired and tmRef
   íK there will be a new namespace and prefix convention for TM
   íK they will be tm:required and tm:ref using the new namspace

   Sebastian: does the SDF use of required apply to anything or
   just interactions?

   Koster: sdfRequired can point to any JSON node, including
   interactions and sdfChoice (enum) elements

   Sebastian: minutes themselves have been approved


   Sebastian: call for review after this TD call, and we're
   planning to publish the updated TD draft May 19

   Sebastian: we can add a sentence to clarify the use of

  PR reviews

    PR 937

   <kaz> [24]PR 937 - WIP: swap securtiy and securityDefinition in
   context file

     [24] https://github.com/w3c/wot-thing-description/pull/937

   Sebastian: #937

    PR 943

   <kaz> [25]PR 943 - WIP: Add proof and proofChain sections

     [25] https://github.com/w3c/wot-thing-description/pull/943

   Sebastian: #943

   McCool: we are rebasing the PR so should close this one

   McCool: the new PR will be based on issue #940

    PR 1085

   <kaz> [26]PR 1085 - WIP: Add Validation Section

     [26] https://github.com/w3c/wot-thing-description/pull/1085

   Sebastian: Validation section

   McCool: could merge but the tagging is not done yet

   Sebastian: agree to merge
   íK maybe we could think more about the naming of the categories

   McCool: we could change it to minimum + basic

   McCool: will add an editor note about the tagging and make the
   name change

    PR 1120 - validation for icon links

   <kaz> [27]PR 1120

     [27] https://github.com/w3c/wot-thing-description/pull/1120

   Cristiano: it validates the size metadata

   Cristiano: adds a validation rule when sizes is present

    PR 1121 - introduce profile term

   <kaz> [28]PR 1121

     [28] https://github.com/w3c/wot-thing-description/pull/1121

   Sebastian: optional term for indicating the profile mechanism,
   URI pointing to a wot profile

   Ege: it could be an array with "and" validation of all profiles
   íK the definition should have a statement about how multiple
   profiles are applied
   íK a consumer may only need to support one of the offered

   McCool: a producer may support more than one profile at the
   same time
   íK need to add this explanation to the profile specification

   Sebastian: there could be a question of which form to consume
   when there are multiple choices in forms

   Koster: the profile may inform that, do we need to provide
   additional guidance in the spec?

   McCool: probably can leave it up to the consumer

   dape: why doesn't the shape for interaction affordances have an
   order number?

   Victor: it is intended to allow any or none (?)

    PR 937 (revisited)

   <kaz> [29]PR 937 - WIP: swap securtiy and securityDefinition in
   context file

     [29] https://github.com/w3c/wot-thing-description/pull/937

   Sebastian: why does securityDefinitions not appear in the

   McCool: it may be a mistake in the file

   McCool: it could be incorrectly generated

   Victor: securityDefinitions is just a container, like
   definitions in JSON schemas
   íK it's only a reference

   McCool: there is confusion between the information model and
   the serialization

   <victor> [30]https://w3c.github.io/wot-thing-description/#thing

     [30] https://w3c.github.io/wot-thing-description/#thing

   McCool: when converted to RDF, they are all flattened to the
   same RDF property

   McCool: for canonicalization, we need to preserve all of the
   nodes in the original document
   íK it's probaby easier to pass them through round trip rather
   than regenerate

   Victor: should the information model then be changed?

   McCool: there is the same issue with named dataschemas in
   additional responses

   Victor: what changes need to be made?

   McCool: start with the rendering

   McCool: we may want to change security to allow objects for
   names schemes

   Victor: it would align better with RDF

   Sebastian: this isn't critical for the specification

   McCool: it blocks progress due to the dataschema issue

   Victor: can provide a TD normalization script

   McCool: sounds similar to canonicalization

   McCool: we can discuss offline and track on the issue tracker

   Sebastian: should we involve JSON-LD people?

   Sebastian: it seems related to #1077

    PR 1104 - Data schema issues

   <kaz> [31]PR 1104 - Address multiple DataSchema issues

     [31] https://github.com/w3c/wot-thing-description/pull/1104

   Sebastian: adds a new term "default"

   Sebastian: adds a note on the "format" term being removed in
   future versions

   Ege: it has been replaced in JSON schema with a new vocabulary
   feature which we could continue to use

   <McCool> @dape that's what I did, not rendering. Trying
   "section" (that is what is done in architecture)

   Sebastian: also adds "pattern" term for constraints using regex

   <Ege> [32]https://json-schema.org/understanding-json-schema/


     [32] https://json-schema.org/understanding-json-schema/reference/regular_expressions.html

   McCool: use of regex should exclude script execution

   McCool: the JSON schema subset is reasonable

   McCool: maybe we could just use the regex subset definition
   text on the JSON schema website

   <McCool> mm: probably the solution is to copy that text into
   our spec, but we need to ask for permission to do so

   Sebastian: merge conflict...
   íK merged

    PR 1085 - Add Validation

   <kaz> [33]PR 1085

     [33] https://github.com/w3c/wot-thing-description/pull/1085

   validation category names

   Sebastian: ready to merge?

   <kaz> [34]PR 1113

     [34] https://github.com/w3c/wot-thing-description/pull/1113

   Ege: implementation of this PR is in the script that generates
   the files

    PR 1122 - terminology

     [35] https://github.com/w3c/wot-thing-description/pull/1122

    PR 1123 - tm namespace

   <kaz> [36]PR 1123

     [36] https://github.com/w3c/wot-thing-description/pull/1123

   Sebastian: new tm namespace and ontology
   íK initially we have only three concepts but more will be added
   íK reviewing changes in the rendered document

   Sebastian: added a rule that extended definitions must be valid
   wrt the base definition
   íK merged

    PR 1124 - canonicalization

   <kaz> [37]PR 1124
