Re: Call for Use Cases & Requirements for WoT Profiles 2.0

Hi,

Just a note to say that we had to cancel the WoT Profiles call today due to
low attendance.

David Ezell and Michael Koster sent their apologies and it was only
Mizushima-san
and I on the call.

We will therefore continue the use cases & requirements discussion
asynchronously.

I would be very grateful if members are able to take the time to review the 6
open PRs
<https://github.com/w3c/wot-profile/pulls?q=is%3Apr+is%3Aopen+draft%3Afalse>
and leave comments and/or *code review approvals* so that we can agree on
an initial set of requirements for the first draft of the WoT Profiles 2.0
Use Cases & Requirements document.

Kind regards

Ben
