FITS Extractor

Overview

A simple module to extend islandora solution pack install processes by adding technical metadata extraction via the File Information Tool Set (FITS).

Behind the scenes, the module tries to get as much metadata as possible from your file by running:

fits.sh -i infile -xc -o outfile

The -xc command can sometimes cause problems, so if that fails, the module tries:

fits.sh -i infile -x -o outfile

Should that fail, technical metadata extraction is aborted and the error is logged in the watchdog (see Chapter 14 - Troubleshooting).

An error my be produced and logged in the apache error.log file even if TECHMD DS extraction is successfull, as the first attempt may fail and log an error while subsequent attempts may succeed.

The most common error printed out to the error.log file that is safe to ignore is as follows: "Exception in thread "main" java.lang.NullPointerException at edu.harvard.hul.ois.fits.FitsOutput.addStandardCombinedFormat(FitsOutput.java:310) at edu.harvard.hul.ois.fits.Fits.outputStandardCombinedFormat(Fits.java:294) at edu.harvard.hul.ois.fits.Fits.outputResults(Fits.java:275) at edu.harvard.hul.ois.fits.Fits.main(Fits.java:186) Error: output cannot be converted to a standard schema format for this file"

Watchdog will be updated when TECHMD DS fail's to generate.
