Learning > presentation > Localization Edit this page Localization Most of the strings specified in presentation rules and visible to the end user can be localized. The library uses a simplified i18next JSON format - it only supports simple key-value pairs (including nesting) without plurals or interpolation. It's important to note that localization happens on the backend, so localization JSON file must be delivered with the backend. Localization in Presentation Rule Sets The strings in presentation rule sets can be localized by using the following format: @LocalizationNamespace:StringId@. Additionally, you can use multiple localized pieces in one string, e.g. Concat_@Namespace:String1@_and_@Namespace:String2@. Last Updated: 15 June, 2021
