A slide deck would be a "Collection", not an "Adaption".
There is no restriction on how you license your collection,
only the CC-BY-SA part must remain under that license.
Thanks for the clarification/pointer; that's really helpful. At the
risk
of being pedantic, one question... What if I layer other elements on
top
of the image, as in slide 18 and later at [1]? Does this now
constitute
a derivative work?
I would think yes.
Presumably if so then I simply need to license the
derivative work as CC-BY-SA, but not the Collection as a whole??
That's where things get a bit murky, but I would think that this is a
reasonable interpretation: The one slide with the modified diagram is
an Adaption, and therefore must be CC-BY-SA licensed. The slide deck
is a collection that contains your Adaption as one part, and therefore
can be subject to a more restrictive license.
BTW, I note my own ommission of the licensing statement for the
cloud in
that slide set. I'll fix that.
This is a very early version, there was no explicit license back then,
probably I or Chris sent you the picture directly for use in your
slides.
