Evidence claims

  • [sourced_fact] RFC 9559, October 2024, Internet Standards Track; authors Lhomme, Bunkus, Rice; defines the Matroska container structure and updates RFC 8794 to allow EBML Element ID 0x80; a container spec, not a codec. source
  • [upstream_claim] Matroska.org describes Matroska as an extensible, open source, open standard multimedia container used for .mkv/.mka/.mks/.mk3d and the basis of .webm. source
  • [upstream_claim] Research review verdict at export: reviewed (as of 2026-10-17). Recorded by the research pipeline, not a hub review outcome; evidence.review stays unreviewed until an independent reviewer records one.
