By means of the TB.CAT 1.3, one may provide several language information (translations etc.) per product. For each multilingual storable information (components, product title, etc.) one receives – in addition to the value – a language tag in the attribute “xml:lang” which indicates the language. At least one language is indicated at any time.
For the import, the languages that are to be imported must first be created together with their import key via the user interface at "Article > Translation > Languages". The import key has to meet the standard ISO-639, i.e. must have at least 2 characters. We highly recommend to follow the ISO standard that is used for the export.The setting which language should preferably be exported to a channel and which language should be used as backup if a translation is missing, is set in the concerned channel settings via the user interface.
