Thanks for the pointer.
The proposal makes technical sense. As he notes, this would be somewhat
of a mirror of how DCMI ended up handling their situation (though with a
very different historical origin).
There are two issues that I can see immediately.
1. Creating two or even three versions of each property would be a hard
sell, politically. And confusing, to users of the properties.
2. I'm concerned that the proposal might be aiming to solve a problem
that isn't really a problem. I'm assuming from your and Jon's
descriptions, that the problem is people who are in the following
situation:
"I have this literal value, and this RDA property with a non-literal
range. What do I do?"
And, the DCAM gives you the answer. You create a statement with the RDA
property, using NO value URI, no VES, and a single value string. In
DC-TEXT [1]:
DescriptionSet (
Description (
Statement (
PropertyURI ( rda:publisher )
ValueString ( "Acme Publishing" )
)
)
)
I fail to see what problem is *not* solve by the above.
Thus, my answer would be NO, we don't want to do that. Noone else in the
RDF community needs to, and neither should we. DCMI had to for legacy
reasons, but we'd only create interoperability issues if we went down
the "multiple properties meaning the same thing" route.
