This schema determines allowable xml file formats
for upload into the DOAJ database.
The schema uses imported codes for the representation
of names of languages devised by the International
Organization for Standardization (ISO) 639-2/B
(bibliographic codes). Please note that when two
codes separated by a dash occurs in the iso 639-2
table then only the first code is used, the
bibliographic one. The terminology code that comes
second is omitted.
