  • the placement of files;
  • the attributes of the files;
  • record structures intended for use in the input or output data streams of an application program when such data streams are required to be organized as sets of records;
  • three nested levels of medium interchange;
  • two nested levels of implementation;
  • requirements for the processes which are provided within information processing systems, to enable information to be interchanged between different systems, utilizing recorded CDROM as the medium of interchange; for this purpose it specifies the functions to be provided within systems which are intended to originate or receive CD-ROM which conform to this Standard.
