The Internet is a part of the whole digital ecosystem (WDE). As such 
it should converge with other registries documenting the WDE or being 
used through the WDE. This calls for the IANA to also capitilize on 
the JTC1/SC32/WG2 experience and study the interest of becoming at 
least ISO 11179 conformant. This should lead Barry's I_D is to be 
"ported" into an ISO 11179 context  (concepts, terminology, 
procedures, I/O formats, creation, relation with information 
provider,  graded reviewers, etc.). And then consider  how it would 
better/lesser fit the IANA needs.

This  was discussed at the langtag registry definition time. The 
langtag registry by its size is most of the IANA registry. It did not 
went through beacause the langtag registry was a new registry and the 
WG's charter did not focus on what ISO 11179 would have brought.

I wish to quote an excellent mail on the matter by Debbie Garside 
(NB. I defeated her FDIS 3166-1 which was an uncorrect political 
move, but analyzing ISO 11179 conformance was a right architectural move).
