localeh

Localeh is a term used in localization theory to describe a descriptor that combines language, regional, script, and heritage information to guide how digital content is presented and interpreted. It is intended to provide a richer, culturally aware signal than traditional locale identifiers, by explicitly incorporating historical or heritage context alongside linguistic and regional data.

The term appears to have originated in academic discussions within computational linguistics and digital humanities in the early 2020s. It is not part of an officially standardized specification and there is no governing body that has adopted localeh as a formal standard. Consequently, references to localeh are predominantly conceptual or exploratory, appearing in research papers or prototype toolchains rather than production-grade specifications.

A typical localeh string is described as including four elements: language, region, script, and a heritage indicator. The language and region align with established codes (for example ISO 639 for language and ISO 3166 for region), while the script uses ISO 15924. The heritage component is a discretionary tag that signals historical or cultural variant considerations. Examples are hypothetical, such as en-Latn-US-historical or fr-Latn-FR-renaissance. In practice, developers often map localeh concepts to existing standards like BCP 47 language tags, using localeh as an internal schema to inform content selection, UX decisions, or archival presentation.

Applications of localeh focus on areas where cultural or historical sensitivity matters, such as educational platforms, museum portals, or heritage-focused interfaces. Limitations include the lack of standardization, potential interoperability challenges with current localization pipelines, and the added complexity of integrating heritage-aware logic into existing tools.
