language attribute (xml:lang) on oaire:file

[ACz-UniBi]

Under discussion is the improvement of the oaire:file element (https://openaire-guidelines-for-literature-repository-managers.readthedocs.io/en/latest/field_filelocation.html#example) by using the xml:lang attribute to indicate the language of the resource content.

Because of the cardinality [0-n], the xml:lang attribute could describe the same item in different languages, so this would be more accurate than the dc:language element.

What would be missing

• a description of the usage
• an example
