Is the conformance to the Web architecture principles what distinguishes the IoT and the WoT ?

Dear all,

After this exiting week at TPAC, I would like to kindly ask you for some
piece of advice about how to define the exact difference between IoT and
WoT for a paper I'm currently writing.

My intuitive definition would be:
 " the WoT starts when the IoT becomes fully conformant with the Web
Architecture principles" -> https://www.w3.org/TR/2004/REC-webarch-20041215/

Yet at TPAC, I heard various strange shortcut definitions such as:
 - the WoT is putting REST architecture principles into the IoT,
 - the WoT is when discovery and semantics is enabled into the IoT
Then at the IRTF meeting this weekend, some discussions were mentioning the
Web of Things in terms that would violate the Web architecture principles.

I tried to find the clear agreed definition of the Web of Things and its
source. So far, my colleague Andrei Ciortea (was at TPAC too) uses the
following two references:

In [1], Erik Wilde emphasizes the importance of the Web architecture
principles, so I would love to consider that his definition be paraphrased
as above: " the WoT starts when the IoT becomes fully conformant with the
Web Architecture principles"

In [2], Guinard, Trifa, and Wilde, describe the Web of Things as follows:
> We position the Web of Things as a refinement of the Internet of Things
by integrating smart things not only into the Internet (the network), but
into the Web (the application layer).
In this paper, the reference to the Web architecture principles disappears.
Although this second definition implies that the Web architecture
principles must be satisfied, I believe it generates confusion among
participants in the WoT group.

Thus, I would be glad to get your opinion on this point:

To what extent would you agree that the strict definition for Web of Things
may be stated as:  "the WoT starts when the IoT becomes fully conformant
with the Web Architecture principles" - -
