Format of the ACIF index object file

General-use Programming Interface and Associated Guidance Information is contained in this chapter.

One of the optional files ACIF can produce contains indexing, offset, and size information. The purpose of this file is to enable applications such as archival and retrieval applications to selectively determine the location of a page group or page within the AFP data stream print file, based on its index (tag) values.

The following example shows the general internal format of this object:

BDI
  IEL GroupName=G1
    TLE (INDEX1)
    ...
    TLE (INDEXn)
      IEL PageName=G1P1
        TLE (INDEX1)
        ...
        TLE (INDEXn)
      ...
      IEL PageName=G1Pn
  ...
  IEL GroupName=Gn
    TLE (INDEX1)
    ...
    TLE (INDEXn)
      IEL PageName=GnP1
        TLE (INDEX1)
        ...
        TLE (INDEXn)
      ...
      IEL PageName=GnPn

The example illustrates an index object file containing both page-level and group-level Index Element (IEL) and Tag Logical Element (TLE) structured fields.
