This is a git archive of a very old (2008) Perl project. Idval is a tool for manipulating files that contain metadata, such as mp3, flac, and other music files; jpeg and other exif image files; and any other kind of files that contain metadata. Two of the principles behind Idval are: 1) that the authoritative source for a media file's metadata is the media file itself, and 2) metadata should be presented in a form that's easy to handle with a text editor. Keep a music collection in lossless FLAC format, and then convert to OGG or MP3 as needed for use with portable music players. The name "Idval" came from "ID Validation". Define rules for a valid set of ID tags, and Idval will show which tags break the rules. Edit the text file that represents the metadata and use Idval to correct the bad tags. Idval works by using "plugins". Idval plugins read metadata from files, write metadata to files, convert between file formats, and manipulate metadata XXX.
