Hi Tom,

I added [[
Note that many standards, such as LCSH, might be seen as belonging to 
several of the categories below. However, we will refer in our report to 
each standard as belonging to just one of the categories, based on their 
typical usage.]]

does that address your concern?

How does this help in our definitions? Do you imply a particular change 
in the definition of dataset that would make things more easily 
understandable?

That's a feature of the semantic web, but not a feature of how most 
library information systems are organized, right?

Put differently: whom among our readership will get this problem (i'd 
guess not many?)

Moreover, the structured metadata record "works" in the explanation, 
while adding the triple perspective here would muddle things, unless you 
have a good suggestion which I can't see!

that sounds like a useful idea.
