CNO-11 codes and Spanish titles are reproduced unchanged; the links to O*NET occupations are AI Changing Work's own judgment and are not an INE correspondence. The English and Korean titles of the ACW-ES-* nodes are AI Changing Work's translations of their Spanish CNO-11 titles; listing them as separate occupations with AI Changing Work codes, and any occupations listed as nearest, are AI Changing Work's own judgment and are not an INE classification or correspondence. INE does not endorse or sponsor this dataset.
This version does not include INE's CNO-11 to ISCO-08 correspondence table, its ISCO-08 titles, or the links that an operator rule adopted because they lay on a path through that table.
