New module: BagIt Creator/Exporter

[vpeil]

The plan: Create bag-it for long-term preservation as planned for SAFE PLN. It would be nice to have a Bagit-Creation-module (also for people in other contexts). Maybe a a validator could also be added here (as planned by @phochste).

There already are some modules:

• Archive::BagIt
• a module not released on cpan: https://github.com/LibreCat/imaging/blob/master/lib/Archive/BagIt.pm by @nicolasfranck

Both use Moose, but maybe we can optimize it by switching to Moo if possible and make more things configurable.

What do you think?

Catmandu::BagIt should be a thin layer on top of a new release of Archive::BagIt. Do you plan to have one Catmandu item exported as BagIt (there is only one set of metadata tags) or multiple items aggregated?

[phochste]

I volunteer to look into this. Already created for Ghent a module based on Catmandu::FedoraCommons. I think it should be one Catmandu item as Bagit. It is your task to construct this item.

I fear I don't think there is much hope for a generic exporter of these type of things, e.g allow for different kind of DIP (in OAIS terms) packages based on a common datamodel.

@phochste : As I remember, Archive::Bagit was your module ;-). I just included it.

I think it's better to rename this module, so we can upload our own module on CPAN. The existing one on CPAN is too limited.

[nichtich]

please don't contribute to the many duplicated CPAN modules but contact the author whethet he is still engaged in his version or it is ok to take over!

[vpeil]

+1 for @nichtich 's suggestion. Duplicate cpan modules are not good.

[phochste]

I had already contact with the authors in the past they are very responsive and willing to add new features.

[vpeil]

maybe they'll share the sources on github? So, we can contribute.
