Metadata extractor

url: http://dark.fhtr.org/repos/metadata
tarball: http://dark.fhtr.org/repos/metadata/metadata-0.1.tar.gz

Description

This package Metadata' comes with a library calledmetadata’ and
a small program called `mdh’.

The library probes files for their metadata (e.g. jpeg dimensions
and camera make, mp3 artist, pdf word count) and returns the metadata
as a Hash.

Mdh can print out file metadata as YAML and package the metadata
with the file.

This package has many dependencies since there is no single universal
metadata header format that all files use. Blame resource forks,
filename
extensions, bags of bytes and mimetypes.

The metadata hash mostly follows the shared-metadata-spec naming.

mdh -p myfile.jpg

create myfile.jpg.mdh, which consists of metadata header +

Any chance this could be expanded to add FLAC and OGG support?

Thanks!
