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

Hi,

Thank you everyone for the input so far on Use Cases & Requirements for WoT
Profiles 2.0.

Just a heads up that there are now 6 open PRs
<https://github.com/w3c/wot-profile/pulls?q=is%3Apr+is%3Aopen+draft%3Afalse>
ready for review which propose an initial set of use cases & requirements
for the Use Cases & Requirements document, based on issues filed
<https://github.com/w3c/wot-profile/issues?q=is%3Aissue%20state%3Aopen%20label%3Arequirement%2C%22use%20case%22%20label%3AProfile-2.0>
and feedback received so far, plus some proposed introductory text.

It would be great to get your review on these PRs so that we can determine
which requirements have broad consensus and which still require further
discussion.

Also, if you think of other use cases & requirements that aren't yet
covered then please do file an issue
<https://github.com/w3c/wot-profile/issues> using the "Use Case" and
"Requirement" issue templates.

I'm aiming to get an initial Draft Note put together by 29th October, which
is when I need to file the final report for my fellowship. Requirements
that come in after that date will not make it into that first draft.

My intention is certainly to continue to refine this document in the
following months in order to eventually publish a final Group Note, but I
won't have dedicated time to work on it after that date.

Kind regards

Ben
