RE: New BNB sample data available

Jeff, these seem to be different schemes, not different prefLabels.  
They've been given equivalence, but have different identifiers. My  
point is that prefLabel choice is not just a question of language, but  
language is the only option we have to creating different prefLabels  
for the same identified concept.
