In general, there is several “layers” of language support in GoodData
• The portal in different langueges per user - that is supported and can be done per user (each user can see different language of the buttons, menus etc. in GoodData portal
• The Metadata localization - names of insights, attributes, facts, column names in tables, etc… - this can be done with the
Metadata Localization feature, where you can import diffrent language versions of these to the workspace and then different users of the workspace can see different names
• “Date dimension data” - this is officially not supported, but you can use the
custom date dimension to upload customized (i.e. translated) date dimension, but that will be for the whole workspace (not per user)
• “General data” - (I believe this is what you are asking for) - this is not supported, you can possibly load different values to different workspaces, but it would not be possible to use different languages in the same workspace (unless you use the dashboard plugins workaround).
