Hi I just thought I'd point out some useful resources;

This message talks about making LOCKSS work with Digital repository software to create a private LOCKSS network.
http://www.sfu.ca/~hgmorris/openaccess-archiving/msg00006.html
Hopefully this helps, as the Repository software, is getting pretty good at supporting the digital preservation work you mention in you original email.

Also the China Digital Museum Project paper 'Building a Distributed, Standards-based Repository Federation' talks a fair bit about how they handled replication and naming of metadata and content using the DSpace Digital Repository software.

The RLG has some nice work that you may find interesting:
Attributes of Trusted Digital Repositories

Audit Checklist for Certifying Digital Repositories (Draft - but good enough for others[MAGDIR] to consider it as a model)

This is not an easy answer for your questions.

my understanding of LOCKSS is that it does not work for straight TIFF /PDFs. There are organizations who can take care of your problems. OCLC is testing the idea of preservation. There is also a research project going on with NDIIPP project, which has a consortium to do digital preservation. (Emory U. is one of the partners).

Or you can just buy some hard drives/tapes and save multiple copies in off-site storage. but in this case, you are responsible for the migration of formats etc.

I like the idea of consortium preservation, but there are other issues to be sorted out.

Subject: [oss4lib-discuss] Storing and keeping safe those hugedigitalisation files

Hello,

I'm going to ask help for something I'd say it is a common situation
nowadays mostly everywhere.

My university is engaged in digitalisation of old material, like most
do.  So do some of my neighbour univesrities.  Our libraries belong to
a local consortium, like most libraries do.  This digitalized material
means, among other things, lots of fat TIFF files, totaling a huge
amount of Gigabytes.  I think most of you know that.

There are plenty disk array vendors willing to sell you their
solutions.  I like specially Capricorn Tech
(http://www.capricorn-tech.com/), due to their Archive.org pedigree,
and Copan Systems (http://www.copansys.com/ ) for their MAID concept.

But one of our most urgent problems is keeping those original TIFF
(and their corresponding PDFs) safe beyond just storing them
somewhere: I mean having more than one copy, doing backups, veryfiying
checksums, automatically fixing the damaged files, maybe changing
formats, etc.  This second part is already invented, and it is called
LOCKSS (http://www.locks.org).  It is a software with anything I could
ask for, and more.

What I have been unable to find in the LOCKSS site is a configuration
model where some libraries, in a local consortium, join together to
keep jointly this material.  Ok, I understand that LOCKSS is designed
to keep the material of [external] publishers.  But when I first
learned about CLOCKSS (Controlled LOCKSS) I immediately thought that
it would address the scenario we are facing in our consortium.  However,
I cannot find it in their web pages.

May I ask how are you addressing this scenario?  If there is a better
forum for this question, I'd gladly ask it there again.

Thanks,

Ferran
