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 for the module or topic you want to modify, select an interface from the Edit Mode drop-down list.
Note Some views might not be available in the advanced interface.
