This article summarizes how the TIBCO Spotfire Language Packs and the languageMappings setting in the Spotfire.Dxp.Worker.Web.config impact the TIBCO Spotfire Web Player.

This article describes how language packs work in Spotfire

TIBCO Spotfire Web Players are available in several different languages via language packs. But the language selected in user's web browser will always take the highest preference. A user whose local language setting is set to English, will still see the Web Player user interface in English, even if the French language pack is deployed. So if a Spotfire administrator wants to default the TIBCO Spotfire Web Player language to French and wants it to automatically force this for each user using TIBCO Spotfire Web Player, then it would not be possible as per the current design.

Though mapping language functionality is present through Spotfire.Dxp.Worker.Web.config file (see reference), it only maps different country dialects within the same language.
The language dialects and countries for which TIBCO Spotfire is translated includes the following:

• de-DE (German / Germany)
• es-ES (Spanish) / Spain)
• fr-FR (French / France)
• it-IT (Italian / Italy)
• ja-JP (Japanese / Japan)
• ko-KR (Korean / South Korea)
• pt-BR (Portuguese / Brazil)
• zh-CH (Simplified Chinese / China)
• ru-RU (Russian / Russia)

For example, if your users have French (Canada) [fr-CA] as the highest preference language in their web browsers, but the Web Player service uses French (France) [fr-FR], you can specify that [fr-FR] should be used even if the web client users have not added [fr-FR] to their lists of supported languages in the browser. This is for what the languageMappings setting in the Spotfire.Dxp.Worker.Web.config can be used.

When English browser languages needs to be mapped to French language deployed on TIBCO Spotfire Server or if German browser language needs to be mapped to French language deployed on TIBCO Spotfire Server, the above mentioned language mapping in Spotfire.Dxp.Worker.Web.config file would not work.
