Seon plugin seonplugin engdatv2 decode

Purpose

Recognize the ENGDAT abstract file in a job and analyze its content. The ENGDAT abstract file is separated into different segments, the following are taken into account:

• UNB: Address code of recipient and sender
• MID: Output of the document ID
• EFC:
  • Filename
  • File sequence number
  • Compression
  • Format (Plaintext & ODDC77 encoding)
• FTX (free text, comment; both for job and single files supported)

The plugin marks the found ENGDAT abstract file with the XML attribute "type=ENGDAT" in order to let it be deleted by the remove ENGDAT plugin.

If a file is marked with the compression type "gzip" in the field EFC4891, the following checks will be executed:

• Is the file really a GZIP compressed file?
• If yes: is the suffix of the file ".gz"? If not, the suffix will be appended to the filename as long as no other file with the same name exists.
• Decompression of the file.
• The name of the file in the ENGDAT abstract file (without the suffix ".gz") will be modified, so the original filename is available.

Requirements

• Seon configuration file /etc/seon.conf exists or the file pointed to via the environment variable $Seon_CFGFILE exists. The referenced configuration file defines the used database, from which the temporary directory and license information will be extracted.
