Flexible Localization is a .NET/Mono library for string-based user interface localization. It offers a hierarchical structure (which can be partially loaded) to organize the strings, as well as support for several independently-localized modules. Localization files are validated against a localization declaration which defines the actual strings that are expected to be in the localization files. The strings themselves can be parametrized and evaluated based on expressions (i.e., different strings can be returned by a localization, based on parameter values).
TongueTied is a Web based application that helps with the creation of keywords with support for multi-language or multi-region resources. One of the key features of TongueTied is that it allows static resources to be exported from the application and can import translations from resources into the application. The following formats are currently supported for both export and import: Java Properties, .NET Resources (.resx), CSV, and Excel. TongueTied integrates an optional work flow around a keyword to track changes to a translation and ensure the validity of that translation. Operators are allowed to query a translation if they believe it to be incorrect.
