A little digression about extractors collisions (more then one
extractors for the same format) from Mac OS Tiger review (by John
Siracusa)

        In Tiger, file metadata is harvested by a set of metadata
        importer plug-ins, one for each type of file. Tiger ships with
        importer plug-ins for many common file types: JPEG images, text
        files, PDFs, etc. Developers are encouraged to write metadata
        importer plug-ins for their file formats. If there are multiple
        plug-ins for a particular file type (e.g. a generic image
        metadata importer and a JPEG metadata importer), the most
        specific plug-in wins. In other words, only one plug-in gets a
        shot at each file.
