<kaz> scribenick: GraemeColeman
mkovatsc: Dave was to present
something on the agenda, but he is not yet on the call
... Any updates?
Soumya: Has circulated a call for papers - if anyone wants to write a white paper describing the current status, that would be highly welcome.
mkovatsc: We need someone in the group to sketch some concrete ideas as to what a submission could look like - paper, book, demo. This should go on the agenda.
<mkovatsc> IoT Week, Bilbao, 4-7 June 2018
mccool: Thinking about writing up some of the work on security.
<kaz> Call for Papers - workshop on semantic interoperability
mccool: Suggest talking offline about writing one large paper other than many smaller ones.
mjkoster: Asked if a submission can be submitted if published somewhere else?
Soumya: No, that is not possible.
mccool: Still possible to publish in the journal later even if published in a previous venue.
Soumya: To mjkoster - you can expand the conference paper and submit it to a journal. This is standard for IEEE.
mjkoster: Putting together a paper on design patterns for interoperability, which will cover WoT as well as general web media. Currently thinking about whether to write this up as a single paper or multiple separate papers.
mccool: Worth throwing around a
bunch of ideas and seeing what works together well. If there's
more than one paper, that's fine, but if they fit together
well, then a single paper would do. But IP protection issues,
and timeline, also need to be considered.
... Let's follow this up on the Thing Description TF meeting,
as that's where this discussion is relevant.

<kaz> Soumya's message on the workshop
dsr: I was asked if we were
interested in doing a workshop (0.5/1 day) on IoT on the WoT on
challenges and opportunities within this field and in the web
of data. Would involve panel sessions, demos, etc. Audience
would be from a broad range, but would include people from
European research projects.
... Has been involved last week.
... last year.
... It would be a good opportunity to make a clear description
of what we've achieved in this group, to disseminate our
results, and to perhaps receive more support from people in the
audience.
... The topic of marketplaces keeps coming up in EU research
projects - so how do you enable open markets in IoT? We could
cover this in our workshop, as to how this fits into the web of
things.
mkovatsc: Other projects
involving marketplaces are going, so (as there are many
academic partners) they may also be interested in getting
involved in the workshop.
... This should be a sticky for the main call (as to whether
main contacts would be interested in getting involved).

dsr: Has taken over as the
activity lead for the Web of Data. Has conducted a survey of
tooling and practices funded by the UK government.
... Created a lengthy questionnaire to get a broad range of
feedback from a wide range of responders. Received around 75
responses. Questionnaire took about an hour to fill in.
... Wanted to understand what people from different backgrounds
were interested in - e.g. sustainability and governance (e.g.
best practices on how to proceed), scaling (translating
overlapping categories and what the practices are), tools and
practices (what can be used to support those practices), links
between communities.
... "How successful are standards"? What is the level of
interest, and what is the adoption level? Logs taken from the
W3C website - there is still considerable interest in
JSON-LD.
... A lot of interest from US and China.
... How are we going to measure what the WoT is?
... Please look at the report, and we can discuss in a future
meeting when people have had a chance to review it.
... Companies are looking at IoT platforms and
platforms-as-a-service, but not necessarily looking at open
markets for services. Yet, based on Google/Apple app stores,
there is potential for linked standards for marketing.
... What changes do we need to make at the W3C? How could they
fund and support standardisation? This needs to be discussed
with stakeholders and W3C members. Does it make sense to change
the funding model for community-based standards?
mkovatsc: Are you planning to provide publicly available metrics for the W3C? Or do we need to develop tools ourselves?
dsr: A bit of both. If we can get the support from the members, we could look at interest over time in a particular standard. We need support of the systems team for that, but they are fairly stretched. Beyond that, how do we gather the information? How many people are implementing the standards? Can we find ways of helping people registering their interest in using those standards?
mkovatsc: Did you identify the most popular specifications for open data - e.g. most popular formats for providing/describing open data?
dsr: Don't have a specific answer - but there is a lot of interest in comma-separated values, whereas others are using e.g. JSON-LD. These results pose the question how do we deal with this?
mkovatsc: So there is no specific information as to which is the most popular?
dsr: We did ask which standards were being used, and whether they were interested more in stability or agility, and the problems around interoperability/different licenses. Second phase will dig deeper into these results.
mkovatsc: It would be interesting to find out the most popular formats, and how they do the description so that we can compare it to what we do.
dsr: Next stage will be to find out the priorities for a second phase, and to secure funding to do this.
mkovatsc: Offer from Sheraton
Hotel to do the meeting. 85 Euros per person per day. Assuming
an average of 40 people, cost will be around 20,000 Euros.
Combined with not having a specific host. Looking for sponsor -
internally, this was felt to be a bit expensive, so possibility
of looking for a second sponsor, or setting up participant
fees. Or, just find a different host.
... Another approach is to look out for other hotels - a
smaller hotel might be possible because we don't need big
meeting rooms.
... Please ask around if you would be willing to host/co-host
this event. Costs expect to be 20,000 Euros, but we hope to
reduce this depending on whether or not we can find a co-host.
We want to avoid registration hassles.
mccool: What days are being used to calculate these costs?
mkovatsc: Saturday to Thursday.
Average of 40 people, as there will be fewer people at the
Plugfest. But, it highly depends on the location and how many
people will show up. It's a rough estimate.
... The day rate is per person, per day. Includes the meeting
room in the service costs per person. We can go back to them
and ask about a fixed price for the numbers who actually show
up.
mccool: I'm assuming the Friday meeting will be paid for by OCF - but we will need to figure this out.
mkovatsc: I was expecting that we would join the co-meeting with OCF, so it wouldn't be on us, but we would use their meeting rooms.
mccool: We would need to check this.
mkovatsc: Any other opinions on what we should do? Should we look for another host - or end up with a meeting fee for participants?
mlagally: Maybe we should have a Doodle poll to find out how many people can come?
kaz: I will create a questionnaire to find out how many people will go.
<kaz> ACTION: kaz to create a WBS questionnaire for Prague f2f
<trackbot> Created ACTION-126 - Create a wbs questionnaire for prague f2f [on Kazuyuki Ashimura - due 2018-01-31].
<dsr> http://www.meetings-conventions.com/Meeting-Facilities/Prague/Hotels
dsr: Potential for self-hosting
in Prague - look for cheaper, "tourist" hotels with meeting
rooms.
... There are some websites and places (such as the above)
which may help find some initial candidate hotels.
... Firstly we need to find out people will attend.
kaz: Let's have more discussion about this on the Chairs list.
mkovatsc: When do they plan to release the next working draft?
<kaz> [TD]
Sebastian: Thing description TF -
we had some discussion about simplified things description
proposal submitted before Christmas. We discussed about
interaction patterns, property/interaction events, are there
enough. Matthias and myself held a separate call with Carsten
Bormann about his concerns regarding property/action
events.
... We discussed what a property means, what an interaction
means and so on - we need a more concrete definition, and
examples, for each. This will help overcome Carsten's
concerns.
... Plan for next meeting - we will concentrate on mkoster's
proposal on new vocabularies. Also giving a status report on
the TD.
mkovatsc: It appears that the
interaction model is not commonly understood in the same way by
everyone. Possibly because properties, actions and events are
quite fuzzy, as they are similar terms to elsewhere. People
therefore need guidance for modeling new system. So it's not
specifically giving definitions, but about giving a description
about how the interaction works and the data action model
works, what the idea behind it is and so on.
... With the simplified TD, the different ideas are not well
documented, or are included in a big PR thread which has now
been merged, so very difficult to follow.
BenFrancis: By having the defaults, is it possible that all of the semantic markup (JSON-LD tags, etc.) could be optional? e.g. similar to OpenGraph data which is added to plain HTML. You have HTML and then you add the extra data. So, could you have a plain JSON description, and then the semantic information is optional.
mkovatsc: Biggest problem is that
LD doesn't support defaults or optional information.
... Whatever is encoded in the TD must be machine
understandable and readable. So, we decided to take an existing
spec (JSON-LD), but this obviously has some limitations. Let's
discuss this in the TD call.
DarkoAnicic: Question about defaults - even if we find away to dismiss them in the TD, they still need to be implemented. This means that every client needs to implement these rules to be aware of the defaults. So I'm not sure if omitting them would be of benefit, because clients still need to be aware of the default values.
BenFrancis: These defaults can be separated out. Problem is that if it's too complex for humans to read, we have a problem of adoption. Doesn't matter how good machines can read it.
mkovatsc: That said, it's quite easy to hard code defaults in some piece of software.
BenFrancis: Look at web app descriptions. These are quite widely adopted and understood.
