.# Abstract
This document defines the Matroska tags, namely the tag names and their respective semantic meaning.
{mainmatter}
Matroska is a multimedia container format defined in [@!Matroska]. It can store timestamped multimedia data
but also chapters and tags. The Tag Elements add important metadata to identify and classify the information found
in a Matroska Segment. It can tag a whole Segment, separate Track Elements, individual Chapter Elements or Attachment Elements.
While the Matroska tagging framework allows anyone to create their own custom tags, it's important to have a common set of values for interoperability. This document intends to define a set of common tag names used in Matroska.
This document is a work-in-progress specification defining the Matroska file format as part of the IETF Cellar working group. It uses basic elements and concept already defined in the Matroska specifications defined by this workgroup [@!Matroska].
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in BCP 14 [@!RFC2119] [@!RFC8174] when, and only when, they appear in all capitals, as shown here.
