1. Stop the VIVO application
2. Update the runtime.properties file to:
   1. Enable language filtering

      
      

      Code Block
      RDFService.languageFilter = true

      
      

   2. Enabled desired languages

      ..such as the following if you wanted: English, Spanish, German, French and Portuguese

      Code Block
      languages.selectableLocales = en_US, es, de_DE, fr_CA, pt_BR

      Private-use subtags are also supported, meaning in the list of selectableLocales might be used local/institutional extension of the language such as fr_CA_x_uqam or de_DE_x_tib.  However, those language files are not in the VIVO/Vitro codebase, meaning it is not possible just to enable those languages without copying of the directory with translations in those languages in the [VIVO_HOME] directory.

VIVO i18n Design

One of the goals of the most recent design of VIVO's internationalization (i18n) implementation is to simplify the process for activating a multi-lingual VIVO site. Starting with the 1.12.0 release of VIVO, all supported languages are built into the application. On start-up, VIVO loads the UI labels ttl files, and annotation and other labels RDF for the languages enabled in the runtime.properties file; see Quick Start above.
