AW: Comments on simplified JSON thing descriptions

I wish you a happy new year and a healthy 2018.

Great to read that you see the proposal as a good step toward.

> In terms of the "bug fixes" you are referring to, do we have a list of those

Matthias refers here to your JSON-LD proposal [1] that do not reflect correct RDF triples. This issue was already raised in the past, e.g., here [2] and [3].

> We are very excited to see this integrated and look forward to the next steps.

To find a common solution quite soon, I would like to invite you to one of our next TD web meetings. It always taking place on Friday 8am CET. How about next week Friday (20. January)? Alternatively, I can try to reserve a slot in January in the weekly plenary WoT meetings that taking place on Wednesday (2pm CET).

I hope, one of the options is possible for you. Please let me know soon.

Kind regards
Sebastian

Betreff: Re: Comments on simplified JSON thing descriptions

Thanks Ben, really appreciate the callout that this was a common effort leveraging previous works.

We really do appreciate the effort of integrating this proposal Matthias, it is indeed a good step towards uniting our efforts as it recognises a simple system that has been working for a while for many real-world IoT systems that do not necessarily require complex transactions. It also makes it fairly compatible with systems such as Google Weave, Nest, EVRYTHNG, HomeKit or Mozillas' Gateway which is really interesting.

In terms of the "bug fixes" you are referring to, do we have a list of those? I could not find one.

We are very excited to see this integrated and look forward to the next steps.

Cheers,

Dom

Please understand that I'm not trying to make the JSON proposal sound more formal than it is, merely to recognise the work of the people who have contributed to getting it to the stage it is now, who I feel don't always get recognised.

A serialisation which can be parsed as both JSON and JSON-LD is an interesting idea I look forward to discussing further.

Dear Ben

Please note that this was not published as IG Note. It is de facto a proposal by three IG Members that uses an incorrect CSS template and colloquially is "your proposal" as you are the editor (just like "Dave's proposal").

Anyhow, looking forward to your comments! Please understand that the WG made a large step toward your TD proposal. The remaining differences are more or less bugfixes to achieve meaningful triples when adding a context and treating it as JSON-LD. I hope that this will enable us to unite our efforts and avoid partitioning the ecosystem...

Happy holidays,
Matthias

Subject: Re: Comments on simplified JSON thing descriptions
Hi,
I'm on holiday at the moment and will reply properly to this interesting GitHub thread in the new year.
I just wanted to mention that the JSON Web Thing Description<https://w3c.github.io/wot/proposals/json-td/index.html> Interest Group Note is not "Ben's proposal". It is the starting point of a combined proposal from Interest Group members (so far Mozilla, EVRYTHNG and Ambrosus Technologies) which builds upon:

  *   The Web Thing Model<http://model.webofthings.io/> member submission which was the output of the EU funded COMPOSE project
  *   Mozilla's Web Thing API<https://iot.mozilla.org/wot/> draft member submission which proposes a JSON serialisation and HTTP & WebSockets protocol binding for the Web of Things

The Interest Group Note is the starting point for a task force in the Interest Group to further incubate a plain JSON serialisation and eventually also an HTTP & WebSockets protocol binding.

I would not necessarily characterise the Interest Group Note as a "subset of a more general approach" provided by Dave's proposal<https://github.com/w3c/wot/blob/master/proposals/dsr-td/td-draft-spec-dsr.md> and I think that proposal may have overlapping but slightly different goals. I'd like to better understand those goals, and the motivation for trying to combine the JSON and JSON-LD serialisations.

Interestingly I think there are still different ideas about the intended use cases of a Web Thing Description and what exactly constitutes the *Web* of Things as opposed to the Internet of Things.

Seasons Greetings

Ben

My regrets for the the main WoT call as I have an appointment I can't change. Sebastian informed me that in today’s call, there will be a presentation of Ben’s Ben’s simplified thing description proposal.

I’ve added some comments on that and invite you to read them and respond, see:

     https://github.com/w3c/wot/pull/363#issuecomment-352996275


In summary: Ben’s proposal is a subset of a more general approach that covers a broader range of requirements, e.g. the ability to pass data with events and actions. In addition, I propose  a general way to address security and synchronisation within the Internet as opposed to the IoT edge protocols. This replace’s Ben’s use of “href” and “links” in his proposal.
