languagesupported

Languagesupported is a property used in software applications and web services to indicate the human languages available for user interaction, content display, and input methods. It may refer to the set of UI translations, documentation, help content, and locale-aware data formats that a product provides to end users.

Representations typically consist of a list of language tags or codes, such as en, fr, es, en-US, fr-CA, and similar IETF BCP 47 tags combining language and region. These lists are often stored in configuration files or metadata and may align with ISO 639 language codes and ISO 3166 region codes.

Languagesupported informs localization workflows, user preferences, and content negotiation. A user may select a preferred language from the supported set, and the application may fall back to a preferred secondary language if translations are incomplete. It also influences resource loading, translation memory usage, and the packaging of language packs.

Design considerations include right-to-left scripts, script variants, font support, and locale-specific formatting for dates, numbers, and calendars. Applications should implement robust fallback strategies, ensure accessibility, and avoid displaying incomplete translations.

Maintenance involves updating the languagesupported list as new translations are added, keeping locale data in sync with resources, and testing across locales. Incompatibilities between language data and UI layout can require adjustments to the interface or content strings.

Related concepts include internationalization and localization, language packs, and resource bundles. Common standards for language tags are ISO 639 and IETF BCP 47, with practical usage often using shortened codes such as en, fr, es, or locale tags like en-US.
