View source for 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 [[Seon plugin seonplugin_remove_engdat|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 "<code>.gz</code>"? 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 "<code>.gz</code>") will be modified, so the original filename is available.

== Requirements ==

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