Import files with metadata values from XML files. This is a crontab task base in Java class packaged in a JAR.

Description:

  • Files to be imported are stored at /home/openkm/import/Output OpenKM server. (Variable SYSTEM_FOLDER+Output).
  • XML files with metadata values are stored at /home/openkm/import/logfile OpenKM server. (Variable SYSTEM_FOLDER+logfile).
  • Files are imported at /okm:root/import. (Variable OPENKM_FOLDER).

Execution description: The first action when crontab task run, is import all file into /home/openkm/import/Output and delete it after has being imported. Then parse xml files located at /home/openkm/import/logfile and inserts corresponding metadata to documents. Finally xml parsed files are deleted also
