A VM4C3PO

We have just set up a vagrant environment for C3PO. It starts a headless vm where the C3PO related functionalities (Mongodb, Play, a downloadable commandline jar) are managable from the host's browser. Further, the vm itself has all relevant processes configured at start-up independently from vagrant, so it can be, once created, downloaded and used as a stand-alone C3PO vm. We think this could be a scenario applicable to other SCAPE projects as well. The following is a summary of the ideas we've had and the experiences we've made.

CSV Validator version 1.0 release

Following on from my previous brief post announcing the beta release of the CSV Validator, http://www.openplanetsfoundation.org/blogs/2014-03-21-csv-validator-beta-releases, today we've made the formal version 1.0 release of the CSV Validator and the associated CSV Schema Language.  I've described this in more detail on The NAtional Archives' blog, 

New QA tool for finger detection on scans

I would like to draw your attention to the new QA tool for finger detection on scans: https://github.com/openplanets/finger-detection-tool. This tool was developed by AIT in scope of the SCAPE project.

 

Checking to identify fingers on scan manually is a very time-consuming and error-prone process. You need a tool to help you: Fingerdet.

Fingerdet is an open source tool which:

EaaS in Action — And a short meltdown due to a friendly DDoS

On June 24th 9.30 AM EST Dragan Espenschied, Digital Conservator at Rhizome NY, released an editorial on rhizome.org featuring a restored home computer previously owned by Cory Arcangel. The article uses an embedded emulator powered by the bwFLA Emulation as a Service framework and the University of Freiburg’s computing center. The embedded emulator allows readers to explore and interact with the re-enacted machine.

BSDIFF: Technological Solutions for Reversible Pre-conditioning of Complex Binary Objects

Documented provenance and the ability for researchers to locate and view original versions of digital records as transferred into an archive are concepts central to archival theory. The continuing ability to enable this is challenged by the numbers of digital records we’re facing; a requirement to follow good digital preservation practice; a need to provide access; the complexity of modern file formats; and the cost of doing all of it. Technological solutions, and techniques borrowed from other disciplines can help reduce costs throughout the transfer process through to the maintenance of digital objects in a digital repository without compromising the integrity asked by archival theory. Using binary diffs and binary patching mechanisms is one such solution that can reduce costs and provide a sound method of documenting all file modifications, from the trivial to the complex – enabling the original record to always be recovered.
