Process the IANA BCP 47 subtag registry

Downloads and parses the IANA Language Subtag Registry into a tidy data frame. Each row represents one registry entry (language, extlang, script, region, variant, grandfathered, or redundant tag). Columns correspond to registry fields such as type, subtag, description, added, preferred_value, and suppress_script. When an entry has multiple values for a single field (e.g., multiple Description lines), they are joined with ";".

Usage

bcp_process_registry(
  url =
    "https://www.iana.org/assignments/language-subtag-registry/language-subtag-registry"
)

Arguments

url

A character scalar giving the URL of the registry plain-text file. Defaults to the official IANA location.

Value

A tibble with one row per registry entry and one column per field. The last_update attribute records the File-Date from the registry header.
