What are the risks involved in a DIY solution like RODA?

Wed, 07 Feb 2018 11:38:21 +0000

I am curious to hear from anyone, particularly smaller institutions, that have implemented DIY solutions with Archivematica, RODA, etc. We have a non-trivial amount of data (300TB - 400TB) that would be cost prohibitive in vendor-based pure cloud scenario using S3 and Glacier.

It seems to me the most cost effective method is to have data on-site in duplicate and replicated to Amazon Glacier, perhaps using a commercial system for the added support. However, its seems (in my ambitious mind) possible to manage a system like RODA in-house and handle the replication ourselves, needing only to pull from Glacier if the fixity checking reports an error. Can someone disabuse me of my fanciful notions? Any horror stories or success stories? Am I right to assume that as long as the bags are stored in Glacier we could migrate those to another system later on if we found maintaining our own system too unwieldy? How horrifying is it to all of you to rely on Glacier as a fail safe option?

Any LTP "Packaging Format" Standard you Support that Makes More Sense than WARC?

Fri, 13 Feb 2015 21:20:18 +0000

Here's my question: Do you prefer a packaging format other than WARC? What other justifications should I take into account? Could you share additional resources for my consideration ( in addition to those below?) And I'll elaborate:

We generally agree that digital permanent records should be kept in open and supported format (tools and communities). We even have a broad selection of formats to chose from (from TIFF/JPEG2000 through PDF/A to XML). What remains, in my view, is a similar broad agreement on the package format that house the above content and linked metadata. The target here is the format of the container, wrapper, or capsule.

There are many requirements that this container should meet, and by far, I like that the container be extendable whereby one can add more content, additional metadata, user contributed context, etc.

Sofar though, .zip container has more or less led the charge, though other formats such as .warc are emerging from studies and comparaisons and showing more promise, which prompts me to ask:
