File Comparison
File Comparison
File comparison plug-ins receive two files and return a value that can be used as part of a preservation evaluation.
Plug-in Parameters
Depending on the specific implementation, a plug‐in may or may not require parameters. If the plug‐in does require parameters, they are populated in the installation of a new instance of the plug‐in.
Usage
The plug-in receives two files (original and migrated) and returns a decimal value that can be used as part of a preservation evaluation. On failure it returns -1.
