The Foreword provides background on the standards process for X3D encodings. The Introduction describes the purpose, design criteria, and characteristics of X3D encodings. The following clauses define this part of ISO/IEC 19776:

  1. Scope defines the problem area that the Compressed binary encoding of X3D addresses.
  2. Normative references lists the normative standards referenced in this part of ISO/IEC 19776.
  3. Definitions contains the glossary of terminology used in this part of ISO/IEC 19776.
  4. Concepts describes various fundamentals of the Compressed binary encoding of X3D.
  5. Encoding of fields specifies the Compressed binary encoding of data types used by X3D nodes.
  6. Conformance describes the conformance requirements for implementations of the Compressed binary encoding.

There are several annexes included in the specification:

  1. Fast infoset tables specifies the initial table values for each syntactic element.
  2. Node compressor registry contains the listing of all registered node compressors.
  3. Examples includes a variety of examples encoded in the X3D Compressed binary encoding.
Bibliography lists references which may have more information.
