WG WoT Thing Description WebConf

From Web of Things Interest Group

The WoT Thing Description task force is responsible for defining the information model for WoT Thing metadata, its interpretation, and its common representation. In addition, the task force covers WoT Binding Templates topics to define the mapping from the abstract interaction model used in the Thing Description metadata to concrete IoT protocols and payload encodings.

Wednesdays at 7am US Pacific / 10am US Eastern / 4pm Europe / 10pm China / Midnight Korea & Japan

This is a WoT WG WebConf and underlies the W3C Patent Policy

Call Moderation

The TF is moderated together by Ege Korkan and Michael Koster

  • Koster: Basic architectural design, document structure, etc. Project management (keep people informed on the process)
  • Ege: concrete description based on the design (constructing the statements for normative/informative style for implementability and testability), call moderation
  • Together: Work on how to improve the spec collaboratively, e.g., schedule of the deliverables, and keeping up with the deadlines.
    • We join the calls together unless there is a conflict.
    • Responsibility is not split, it is shared. If someone asks a question, both should be able to answer it.
  • Feedback from the TF:
    • Cris: Testability should be assured
    • Kaz and Koster: TD still does the governance of testing, we are responsible. To be further discussed and the relationship to testing TF clarified.

Zoom

IRC

The IRC is used for the minutes, speaker queue, and sharing links etc.

Agenda

Cancellations: See https://www.w3.org/WoT/IG/wiki/Main_WoT_WebConf#Cancellations_and_Schedule_Updates

Note: Wednesdays start with TD topics and Thursdays start with Binding Templates topics. The other topics will be allocated dynamically based on time left. We will strikethrough discussed topics.

Backlog

For all members, you can edit this header before the meeting and add your points. Please do not insert your topics directly into one of the other headers. TF Moderators will adjust the agenda accordingly.

  1. Example Item 1: Discussing topic ABC (Ege Korkan)
  2. Errata Management: https://github.com/w3c/wot-thing-description/issues/2019
  3. Historical Data Analysis: https://github.com/w3c/wot/blob/main/planning/ThingDescription/analysis-historical-data-work-item.md
  4. Needed by other TF label: https://github.com/w3c/wot-thing-description/issues/1980
  5. Example Existing Requirement (like a design decision) Discussion: https://github.com/w3c/wot-thing-description/issues/1824
  6. JSON Schema standard adoption strategy
  7. Reviews of the individual bindings to extract use cases
    • Waiting for UC Pipeline to be defined
    • Extracting missing mechanisms and documenting them
      • Missing op mappings that are possible
      • Missing protocol mechanisms (e.g. can we do message pattern X of protocol Y in the binding Y?)
        • Asking for more input from experts can help
        • CA: An example would be the request-response pattern in MQTT. If we can not do it, it should be a use case. If we can, it is a lack of documentation, thus a simple issue.
        • MQTT: HiveMQ
        • CoAP: Jan Romann knows people. We can also ask Klaus Hartke from Siemens
        • HTTP: Needs people but the WG is quite knowledgeable in general
        • Websocket: Needs people
        • SSE: Needs people
        • Modbus: We got a lot of input already but can be double-checked
        • BACnet: Quite recent, needs more time

TD

  2. Toolchain Discussion
    • Sub TF new slot: Tuesday 14:30 CEST (8:30 EDT)
    • Report out of the Sub TF
      • Reached "the limits": We are now seeing some issues that need to be addressed by LinkML itself. We have decided to proceed as follows: Categorize issues and contribute back when possible. See labels below.
      • Issue Labels: "Post Processing Forever", "Intermediata Post Processing", "Wait for LinkML fix". Plus, each type of generator will have a label (e.g. "JSON Schema", "SHACL" etc.)
      • This will be probably repeated for each generated document type. For now we are concentrating on JSON Schema.
      • Existing documents we have are in HTML. For those, we will keep it in HTML for now. Once the data model and generators are done, we can reevaluate changing to markdown. Once the process is adopted for bindings, new bindings can start in md directly since they do not have anything old to take care of.

  1. Reorganization of Work Items: https://github.com/w3c/wot/blob/main/planning/ThingDescription/work-items.md

  2. Project Management Proposal: https://github.com/w3c/wot-thing-description/blob/main/proposals/project-management/project-management.md
    • New tables for non UC work items or integrate to first table with new categories. Ege to come with a proposal

Use Case Discussion

  1. What to do here, what to do in Use Cases TF:
  2. Also see https://github.com/w3c/wot-usecases/issues/261
  3. Expectations of stakeholders from the use case TF and the use case process:
    • Let's create an issue in the UC repo after the call with the information below
    • TD TF Participants (first priority)
      • Ege:
        • 1. An issue created in the TD repository that has all the information needed to start working on the discussions to design the feature. This means that the TD TF is not required to contact the people involved in the creation of the use case and requirement and that no other document but the issue is required to create the feature
        • 2. The person to contact who is interested in implementing it in a WoT implementation (Thing or Consumer). If the feature is needed by TD TF participants, this can be omitted by putting the TF participant as the contact. This is important so that we do not work on features that no one is interested in implementing, ending up removed after testing for the implementation report. (+1 from Cris)
      • Luca:
        • 1. So that we do not lose something. E.g. there is a whole application area due to a missing feature.
        • 2. From a Marketing POV: People who are looking for a problem can find the solution to their problem. -> That implies that from use cases and requirements we point to the features (UC -> req -> feature)
      • Cris:
        • 1. Something actionable that we can discuss in the TD TF and implement into the spec.
    • Users or Implementors of TD (and WoT)
      • This stakeholder group should be clarified. E.g. do we mean developers, architects, end user (non technical person), etc.
      • Ege: Identify a similar use case to theirs and get more context about a specific feature.
      • Luca: There should be no need to go to use cases document to understand something. If that happens, our spec is not clear enough. For a more advanced user, we can show a way to submit a UC if they find a gap in the respective chapter of the spec. This will help us get more specific input. This can be guided via an issue template.
      • Cris: It would help to know if they are in "uncharted" territories. In that case, we can say that "you may have issues since we did not explore this area yet". If it already exists, then they can refer to the existing work and even contact the people (including WG/IG people) who were involved in that use case.

  3. TO BE TRACKED VIA USE CASES TF: Reviews of the individual bindings to extract use cases
    • Extracting missing mechanisms and documenting them
      • Missing op mappings that are possible
      • Missing protocol mechanisms (e.g. can we do message pattern X of protocol Y in the binding Y?)
        • Asking for more input from experts can help
        • CA: An example would be the request-response pattern in MQTT. If we can not do it, it should be a use case. If we can, it is a lack of documentation, thus a simple issue.
        • MQTT: HiveMQ
        • CoAP: Jan Romann knows people. We can also ask Klaus Hartke from Siemens
        • HTTP: Needs people but the WG is quite knowledgeable in general

  2. Project Management Proposal: https://github.com/w3c/wot-thing-description/blob/main/proposals/project-management/project-management.md

Use Case Discussion

  1. What to do here, what to do in Use Cases TF:
    • We do issue labeling here first.
  2. Also see https://github.com/w3c/wot-usecases/issues/261
  3. Splitting issues to find "promising use cases"?
    • They label issues that have use case like content with "Needs use case" label. The issues that do not get the label are probably one of the following:
      • Tooling: probably already has Tooling label, please add it otherwise.
      • Internal work: Example 1, Example 2. You should use the appropriate label or note the issue number for a quick discussion in the next calls.
      • Fixing something simple: Example 1, Example 2. You should use the appropriate label or note the issue number for a quick discussion in the next calls.
      • Unclear issues: In this case, use "Not Clear" label.
    • They evaluate the relevance of the issue to the charter. E.g. use cases that are more theoretical are lower prioritized, use cases with real application behind are higher prioritized.
      • First of all, "Needs use case" label should be present.
      • If another TF has raised it, use "Needed by other TF" label.
      • If you are not sure about the relevance to the charter, use "Relevance Unclear" label. If the group agrees, we will remove the "Defer to TD 2.0" label.
      • If you think they are relevant for the charter, make sure that they have "Defer to TD 2.0" label.
      • In the end, we will provide Use Case or User Story descriptions for the issues that have "Needs use case" and "Defer to TD 2.0" label.
    • Call participants on the 24.01 are to be considered.
    • We should look into Binding and TD repositories.
      • Together there are 268 issues. We are about 9 or 10 participants
      • We can give about 25 issues per TF participant. We should ask if they prefer TD or Binding issues first of all. Then split:
        • We cannot say issues with number 25 to 50 belongs to person X. There may be no issue 26 since that can be a PR or it is an already closed issue.
        • There are, luckily, 25 issues per page, except for the last page. So one page per participant makes sense but we should note down the issue range since a new issue will push all other issues by one.

  1. Reorganization of Work Items: https://github.com/w3c/wot/blob/main/planning/ThingDescription/work-items.md
  2. Project Management Proposal: https://github.com/w3c/wot-thing-description/blob/main/proposals/project-management/project-management.md

Use Case Discussion

  1. What to do here, what to do in Use Cases TF
  2. Data Mapping
    • Issues/Discussion in BACnet, Modbus, recently Profinet. Relevant discussions before in LWM2M or Philips Hue.
    • Proposal: Start work on this by gathering all the relevant existing inputs into the https://github.com/w3c/wot/blob/main/planning/ThingDescription/td-next-work-items/usability-and-design.md#data-schema-mapping and then move it to the new use cases workflow.
    • Notes:
      • Analyze PACK (or similar) mechanisms found in programming languages such as Python.
      • We need to differentiate serialization with concrete packing mechanisms and those that dont. So paying attention to contentType and contentCoding is needed.
    • Luca B. will do the first PR on this (not to TD spec but to wot repo) and people can comment with any missing discussion so far.
    • There can be proposals but no PRs to change spec at this point
  3. Use Case Analysis and Requirement Extraction Workflow
  4. Backtracking some additions in TD 1.1 and 1.0:
    • User Story is something written like a user.
      • As User X, I want to ABC so I can achieve XYZ
      • It should be specific to WoT (e.g. I want to monitor my trucks so I can have less maintenance costs is not good)
      • We can specify types of users (personas)
    • Thing Models
      • Use Case: Managing/Representing a set of instantiations of the same model of a device. Correlating (search) in a collection of TDs that represent the same model of the device.
      • User Story: TBD
      • Requirement: One file to represent a model of the device
      • Feature: Thing Model mechanism
    • Extension/Submodel in Thing Models
      • Use Case: Reusability. Consistent affordance definition for reuse, e.g. of temperature.
      • Requirement: Reuse of existing definitions found in Thing Models
      • Feature: tm:submodel, tm:extends etc.
    • synchronous word in actions
      • Use Case: Interacting with two robots that behave slightly differently (one replying rightaway and moving, other moving and then replying)
      • User Story: TBD
      • Requirement: A keyword should indicate this behavior
      • Feature: "synchronous" keyword with boolean type
