Publicat per jamesks el 28 Octubre 2008 en English. Última actualització de 29 Octubre 2008Lots of way-tracing from Yahoo. Now Madrid has some suburbs, though I am glad I do not live there.

AFAIK, you can't use Geonames data in OSM. Geonames get data from anywhere it can, and doesn't meet the OSM license requirements. See osm.wiki/index.php/Geonames
As always for new data sources, if it's not mentioned that is ok to use on the wiki, bring it up on the legal mailing list to verify it's fine to use.
