4.2.5 - The repository shall have access to necessary tools and resources to provide authoritative Representation Information for all of the digital objects it contains.
SP identifies and validates each file using software tools from the FITS package. It makes use of DROID for format identification during the ingest process where a file format is associated with each file. The repository also employs JHOVE as a tool for further format-specific identification, validation and characterization of the file. SP links the file format to its entry in the external format registry, PRONOM.
