Notes:

  1. the example URI, 'info:lc/xmlns/mods-4.0' , is at present hypothetical. It could be used as the MODS namespace URI for MODS version 4, but there is no MODS version 4 yet and the namespace URI for future version 4 of MODS is not yet assigned.
  2. The URI info:lc/vocabulary/languages identifies the languages codelist, and the URI info:lc/vocabulary/languages/abk identifies the language code 'abk' the language code for the language Abkhaz.
