Format of the output document file

This topic contains General-use Programming Interface and Associated Guidance Information.

ACIF can create three separate output files, one of which is the print file in AFP data stream format. In doing so, ACIF might create these structured fields:

  • Tag Logical Element (TLE)
  • Begin Named Group (BNG)
  • End Named Group (ENG)

The TLE is described in Format of the index object file; the other two structured fields are described in this section. Example of code that contains group-level indexing and Example of code that contains group- and page-level indexing illustrate the two possible AFP data stream document formats ACIF can produce.

Example of code that contains group-level indexing

BDT
  BNG Groupname=(index value + sequence number)
    TLE (INDEX1)
    TLE (INDEX2)
    ...
    TLE (INDEXn)
      BPG
        Page 1 of group 1
      EPG
      BPG
        Page 2 of group 1
      EPG
      ...
      BPG
        Page n of group 1
      EPG
  ENG
  ...
  BNG Groupname=(index value + sequence number)
    TLE (INDEX1)
    TLE (INDEX2)
    ...
    TLE (INDEXn)
      BPG
        Page 1 of group n
      EPG
      BPG
        Page 2 of group n
      EPG
      ...
      BPG
        Page n of group n
      EPG
  ENG
EDT

Example of code that contains group-level indexing illustrates the format ACIF produces when it converts and indexes a print file with group-level indexing.

Example of code that contains group- and page-level indexing

BDT
  BNG Groupname=(index value + sequence number)
    TLE (INDEX1)
       ...
    TLE (INDEXn)
      BPG
        TLE (INDEX1)
        ...
        TLE (INDEXn)
        Page 1 of group 1
      EPG
      ...
      BPG
        TLE (INDEX1)
        ...
        TLE (INDEXn)
        Page n of group 1
      EPG
  ENG
  ...
  BNG Groupname=(index value + sequence number)
    TLE (INDEX1)
       ...
    TLE (INDEXn)
      BPG
        Page 1 of group n
      EPG
      ...
      BPG
        Page n of group n
      EPG

Example of code that contains group- and page-level indexing illustrates an input file that has already been indexed (tagged) and converted to MO:DCA-P format. This example shows that you can index (tag) both groups and pages from an application.

In this section:

  1. Page groups
    Page groups are architected groups of one or more pages to which some action or meaning is assigned. Consider the example of the bank statement application. Each bank statement in the print file comprises one or more pages. By grouping each statement in a logical manner, you can assign specific indexing or tag information to each group (statement). You can then use this grouping to do actions such as archival, retrieval, viewing, preprocessing, and postprocessing. The grouping also represents a natural hierarchy. For the AFP Workbench Viewer, you can locate a group of pages and then locate a page within a group. If you again use the example of the bank statement application, you can see how useful this grouping can be. You can retrieve from the archival (storage) system all of the bank statements for a specific branch. You can then select a specific bank statement (group-level) to view and select a tagged summary page (page-level).
  2. Begin Document (BDT) structured field
  3. Begin Named Group (BNG) structured field
  4. Tag Logical Element (TLE) structured field
  5. Begin Page (BPG) structured field
  6. End Named Group (ENG), End Document (EDT), and End Page (EPG) structured fields
  7. Output MO:DCA-P data stream
