Yes, I had seen that a few weeks ago. I have no idea what their structure 
is behind the scenes, but they probably downloaded the language code table 
and the macrolanguage mappings table from the SIL website:

and plugged the data into their processes. These two tables (+ the data on 
B/T identifier equivalents compiled from the ISO 639-2/RA site or from the 
sil site) contain all the data that they would need to create the language 
codes part of the table displayed as part of any entry on a language.

did anyone know?

I just noticed that Wikipedia includes the ISO 639-1, 639-2 (B and T) and
639-3 language codes in articles relating to specific languages. I wonder
how/if they keep them up to date.
