Language Metadata Table

The Language Metadata Table (LMT) was created to provide a unified source of reference for language codes for use throughout the media and entertainment industries. LMT’s mission is:

  • To create a standardized table of language codes for implementation by entertainment and other industries using IETF BCP 47 (a.k.a., RFC 5646).
  • To facilitate efficient and consistent LMT usage through best practices.
  • To extend LMT code values through vetted field definitions and approved language code values with a community of thought leaders who focus on information and data from the business, professional associations and academic institutions through the exchange of knowledge and collaboration.
