[ANN] Metadata 1.0-rc2

Ilmari Heikkinen

9/19/2007 9:09:00 AM

Getting close to the 1.0 release of the metadata library.
If there are no major problems with this release candidate, that is.

tarball: http://dark.fhtr.org/repo.../metadata-1.0-...
git: http://dark.fhtr.org/repo...

Changes
-------
* bittorrent .torrent support
* untested ape/musepack/wavepack support with apetag gem
(couldn't find any ape samples)
* 'name' and 'author' parsed from mplayer output
* more documentation
* better handling of images that have no exif info
* tested ra, wma and m4a
* tested more image formats
* fixed audio samplerate and channels for videos
(i.e. convert the string to int.)
* bin/mdh now prints the metadata as the default action.
Use -c to create an MDH file.
* MDH files have a "MDH#{version_byte}" header now,
the validity of which is checked by mdh.

Thanks

Konrad Meyer for his patient testing and bug reports.
Darren Kirby for the heads-up on wmainfo's ASF-parsing capabilities
(along with being the author of wmainfo-rb and flacinfo-rb.)


Description
-----------

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

The library probes files for their metadata (e.g. jpeg dimensions
and camera make, mp3 artist, pdf text and word count) and returns the
metadata as a Hash. All strings in the metadata are converted to UTF-8.

The `mdh'-program can print out file metadata as YAML and package the
metadata with the file.

The metadata hash follows the shared file metadata spec naming, with some
additional fields, see list at the end of this file (Appendix A.)

For details on the MDH file format, see the end of this file (Appendix B.)


Usage
-----

# print out metadata for myfile.jpg
mdh myfile.jpg

# create myfile.jpg.mdh, which consists of an MDH metadata header + myfile.jpg
mdh -c myfile.jpg

# print out the metadata header from an MDH file
mdh -e -p myfile.jpg.mdh

# strip out the metadata header from an MDH file and save it to myfile.jpg
mdh -e myfile.jpg.mdh

# print out the list of options
mdh -h

irb> require 'metadata'
irb> Metadata.extract('myfile.jpg')
irb> Metadata.extract_text('myfile.pdf')
irb> Pathname.new("myfile.jpg").metadata


List of supported formats
-------------------------

Audio:
Whatever you manage to make mplayer play.
Plus special handlers for FLAC, m4a, ape, musepack, wavepack and wma.
Successfully tested with:
mp3, flac, ogg, wav, ra, wma, m4a
Should also work:
wv, mpc, ape

Video:
Whatever you manage to make mplayer play.
Successfully tested with:
wmv, mov, divx, xvid, flv, ogm, mpg, mkv

Images:
Should handle pretty much anything (apart from ORF.)
Successfully tested with:
jpeg, png, gif, nef, dng, crw, pef, psd, tga, tif, xcf, xpm, ppm, bmp

Documents:
Successfully tested with:
pdf, ppt, odp, sxi, ps, ps.gz, html, txt
Should work:
- OpenOffice docs work to some degree (personally, I'm using unoconv to
convert OO docs to temp PDFs for the text & dimensions extraction, so
those bits of data are missing.)
- MS Office docs to some degree (ppt at least, doc and xls should work too,
dimensions missing due to the above temp PDF -thing.)

Others:
- BitTorrent .torrent files
- Archive contents
- Whatever `extract' outputs and I am handling


Requirements
------------

* Ruby 1.8

* Tons of metadata extraction programs and libs.
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.

List of gems:
flacinfo-rb
wmainfo-rb
MP4info
id3lib-ruby
apetag

List of Debian packages:
dcraw
libimlib2-ruby
extract
libimage-exiftool-perl
poppler-utils
mplayer
html2text
imagemagick
unhtml
pstotext
antiword
catdoc
shared-mime-info

* You do want to install the latest versions of dcraw and
shared-mime-info to be able to handle camera raw images.
http://cybercom.net/~dcof...
http://freedesktop.org/wiki/Software/shared...

* Python + chardet library
http://chardet.feedp...


Install
-------

De-compress archive and enter its top directory.
Then type:

($ su)
# ruby setup.rb

These simple step installs this program under the default
location of Ruby libraries. You can also install files into
your favorite directory by supplying setup.rb some options.
Try "ruby setup.rb --help".


Appendix A: Additional metadata fields
--------------------------------------

This list contains the metadata fields added to the shared
file metadata spec.

Appendix B: The MDH file format
-------------------------------

MDH files are built as follows:

bytes | content
---------------
3 | "MDH" - MDH file format identifier
1 | "\x01" - MDH file format version number
4 | Long, network byte order - the size of the metadata struct in bytes
var | YAML - The MDH metadata struct
var | The actual file contents

All string fields in the metadata are UTF-8.

I'm getting some issues with .torrents. Ex:
$ mdh -p Fedora-7-i386.torrent undefined method `to_utf8' for
["F-7-i386-DVD.iso"]:Array
undefined method `to_utf8' for ["F-7-i386-DVD.iso"]:Array

Thanks, fixed. Along with extracting more metadata from .torrents
and handling flacs with id3 tags better.

Oh, and, if there are any other filetypes that could do with more
metadata, feel free to request. Especially if some other program
shows it. And still more especially if the other program is a
cmdline app with a debian package ;-)

I've actually been doing all this testing under Fedora 7, all the packages
needed are here IIRC but they may have slightly different names (especially
debian -dev -> fedora -devel).

In short, no (to both).
In earlier messages I asked for a gem too, and it turns out this is hard to do
because of a python script that's included. And as far as windows, I think a
lot of this relies on shelling out, which windows... doesn't have. So you
might look for another solution (or go to *nix).
