Hi, I checked MARC country codes against ISO country codes. I saw some différences. As ISO 3166 standard is used in some RFC, i suggest to use ISO3166 codes in MODS rather than MARC codes. I worked today on an xml file that made the reliationship between these different codes and names : http://mods-fr.sourceforge.net/ follow the link "Pays". http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/*checkout*/mods-fr/xsl/countr ies.xml I'll give you next week the differences between these standards.
