Extensible Binary Meta Language (EBML) is a generalized file format for any kind of data, aiming to be a binary equivalent to XML. It provides a basic framework for storing data in XML-like tags. It was originally designed as the framework language for the Matroska audio/video container format.

EBML is not extensible in the same way that XML is, as the XML schema (e.g., DTD) must be known in advance.
