I (still) won't comment on which predicates you use to describe equivalence :-)
My observation was that it was hard (impossible unless you use sameAs.org :-)
?) to get from your 3-letter URIs to the 2-letter ones, which seemed strange.
To be more specific:
If someone gives me the URI
http://worldbank.270a.info/classification/country/AND I can find nothing about
it, not even http://worldbank.270a.info/classification/country/AD.
In fact this actually contradicts principle 3 of Linked Data - you don't
Provide useful information, as far as I can tell.
Not a big deal - just a link (of some kind) to the 2-letter one would help.
In fact, I think, from what you say, you think the link is there from 3-letter
to 2-letter.
But I couldn't find it.
I am looking at http://worldbank.270a.info/classification/country/AND.turtle
Best
