The "source" of the Matroska specification is an XML file hosted on Matroska.org's GitHub repository (although that table has not been updated since 2018). This table is also used to generate the semantic data used in libmatroska and libmatroska2.
Specification information is published concurrently in two locations: The Matroska website and the Internet Engineering Task Force (IETF) Matroska Media Container Format Specifications datatracker. Since 2018, the in-process specification for version 4 of the Matroska Media Container Format has been published as a sequence of Internet Drafts, available at Matroska Media Container Format Specifications datatracker. An early version of the specification dated January 11, 2009 authored by Alexander Noé is available on the Matroska site but it is not clear which versions are covered in this document.
MPEG-2's specification is ISO/IEC 13818 and its first approvals were in 1994. Ten parts have been published; parts 1, 2, 3, and 7 are central. Part 2 concerns the coding and specifies profiles and levels.
