Q: Is is allowed the use of any other language besides English in the text of the metadata files?
A: To be noted that English is the standard language for all metadata files, if extended content is in any other language, it should be flagged. To be noted that exception from this case is for the title of publications, news releases, laws, name of the questionnaires, NUTS regions etc. which should be accompanied with a translation in English of these titles.
If other than English words are used, and not part of the exception mentioned above – reject the file.
