There are two interfaces that you can use to enter metadata.
Basic interface Simpler and easier to work with, it does not include all of the fields available in the advanced interface (depending on the view) and only allows you to enter terms in the default language.
Advanced interface enables you to specify a language and enter terms in multiple languages, and you can enter multiple values for some fields (e.g. multiple keywords).
On the Edit Metadata page, use the Edit Mode drop-down list to select an interface.
Note Some views might not be available in the advanced interface.
