Abstract ISO/IEC 8825-2:2008 specifies a set of Packed Encoding Rules that can be used to derive a transfer syntax for values of types defined in ISO/IEC 8824-1. These Packed Encoding Rules can also be applied for decoding such a transfer syntax in order to identify the data values being transferred. The encoding rules specified in ISO/IEC 8825-2:2008:

  • are used at the time of communication;

  • are intended for use in circumstances where minimizing the size of the representation of values is the major concern in the choice of encoding rules;

  • allow the extension of an abstract syntax by addition of extra values, preserving the encodings of the existing values, for all forms of extension described in ISO/IEC 8824-1;

  • can be modified in accordance with the provisions of ISO/IEC 8825-6.
