Keys beginning with language:*=* indicate the languages offered or taught at a point of interest. The specific degree of language usage may vary from one type of facility to another and from one region to another. These keys are more commonly used in multilingual regions where, for instance, language support may be posted on a shop window.
Usage
These keys are commonly used to indicate, for example:
- The medium of instruction at an amenity=school, amenity=kindergarten, or amenity=childcare (may be part of a language immersion program)
- The languages taught at a amenity=language_school
- The languages that are translated to at a office=translator
- Language service offered to customers of various kinds of retail establishments, such as amenity=restaurant, shop=*, tourism=hotel, and office=insurance
- The languages in which services are conducted at an amenity=place_of_worship
- The user interface language options offered by an amenity=atm, amenity=vending_machine, or amenity=payment_terminal
Values
- language:language code=main/yes - where language code is a two-letter ISO 639-1 code or three-letter ISO 639-2 code
- main - main language offered/taught
- yes - additional languages offered/taught
Example:
- language:de=main - The main language taught in this language school is German.
- language:en=yes - English is taught in this language school.
