As well as blogging about digital preservation here, I've also got a blog on the Open Planets Foundation website where I'll post about OPF issues. I've just posted my first blog entry there: Community and code

I don't know if it was coincidence, or by design, but the latest issue of the International Journal of Digital Curation contains two very similar articles. One is from the Planets Project, is co-authored by me, and is called A Framework for Distributed Preservation Workflows. The other is called An Emergent Micro-Services Approach to Digital Curation Infrastructure, and is by Stephen Abrams et al from CDL. These two separate papers describe two approaches to building preservation systems, which despite having been developed independently appear to be converging towards a single, consistent design.

Inspired by the excellent @dhnow social news service, I've set up a news aggregator for digital preservation. The @digipresnews account follows people involved in digital preservation, and I use the Twitter Tim.es service to extract the top links of interest. This also provides an RSS feed, which is piped back into the Twitter account via twitterfeed.

Of course, this type of aggregation is only as good as its sources, so if I've missed a digital preservation tweeter, or included someone you think I shouldn't have done, contact me @here or here.

This notebook is a place to record useful tidbits of information about digital preservation. The Wikipedia page on Digital Preservation provides quite a good overview of the field, but this notebook intends to dig a little deeper.

Roughly speaking, the technical side of digital preservation can be broken down into two parts:

• Preserving the bytes.
• Preserving access to the digital objects those bytes describe.

Most of this notebook deals with the latter issue, i.e. with how to preserve the meaning of digital objects so that they remain accessible over time. Of course, all of that work is based on the assumption that we can keep the actual binary data safe from bit-rot, and so the first section will look at that issue.
