Technical Summary
This document defines format considerations for Extensible Binary
Meta Language, a hierarchical file format for efficient delivery
of binary data in defined Elements inspired by XML. It proposes
definitions for creating and validating EBML Schemas that define
the use and interpretation of Elements within EBML Documents.
Working Group Summary
This document has been adequately reviewed by working group
members and others, through both mailing list discussion and
Github issues and pull requests.
One minor issue was how to define EBML Elements in a Header
document in a forward-compatible way. It was decided Headers
could require a specific, minimum or maximum EBMLVersion
(which might have different implementations of Elements).
Most recent discussion has focused on how Element IDs (unique
identifiers for EBML Elements used within a Schema and Document)
should be defined and encoded (as Variable Size Integers) with regard
to IANA registration.
Document Quality
There are already several existing implementations of the specification,
including ffmpeg, vlc, and most major browsers and many TV boxes.
This is a very readable and clearly written document, and represents
the inclusion of multiple recent revisions resolving minor outstanding issues.
There appears to be strong group consensus on this document’s readiness
to move forward in the standardization process.
Personnel
The document shepherd is Steven Villereal.
The responsible Area Director is Alexey Melnikov.
