Thanks Kingsley.
I'm not sure why you have raised all this again.
I simply suggested to Richard another way of doing what he wanted.
You then asked me whether what you had proposed failed to resolve his
problem.
I can't say whether it does, but perhaps Richard can better answer that.
But it would have been rude of me not to attempt to answer your direct
question to me.
My view is that probably none of this now addresses Richard's fundamental
problem, I think, (which I was trying to do in my message and which Toby is
also trying to address). He needs reliable properties that relate countries
to their geography. It is a problem of ontology and published data, not how
to access it.

Išll trim things a bit to try to get at some essence.

And a very nice beachhead.
But your solution only talked about the source at http://lod.openlinksw.com
It is also interesting to consider how it might interact with other sources.

Ah. I think this is perhaps getting to the nub.
I don't see Linked Data as relating to search - more to lookup, as in a
database record lookup by key.
The semantic web is more like one big database then a big file system.
So you project into the Linked Data world by finding the URI you want, and
from then on in it is URIs all the way down, until/unless you want to show a
human something, when you project back into their language.

OK, that's how to start.
But he doesn't need to do that - he said he already had the URI he wanted:

For me to put in a URI such as http://dbpedia.org/resource/New_Zealand and
get the Linked Data back.

Have you tried typing in the URIs that Richard specified?
However, looking at it, I think it may just be a bugette, which confused me.

Actually, it is a Linked Data site that has uploaded a lot of data from
other places, and also dynamically gets more. I assume by instance you mean
it is an instance of the class of Linked Data sites.

An interesting question.
I am certainly uncomfortable with responses that never seem to mention the
idea that Linked Data is a Web of Data, by suggesting the use of data that
might be accessed on domains other than http://lod.openlinksw.com .
But this would be for another thread, and I don't have the time to do that.
