graboid

Graboid is a GUI that copies files from one storage to another. It does some file identification using Siegfried or FITS via a FITSServlet.

It creates a UUIDv4 and calculates hash sums.

Output is written to a CSV file when using Siegfried or to an XML file using FITS.

Graboid is work in progress and should not be used in productive environments.

CSV schema using Siegfried

Filename, Size in Byte, Registry, PUID, Name, Version, MIME, Byte Match, Identification Note, Hash sum, UUID

XML output using FITSServlet

work in progress
