What are the current data preservation practices within your field?
Data preservation practices are really non-existent. If people do anything it’s usually saving something to DVDs or tapes, and then sticking it somewhere to rot. I’ve spoken to my colleagues, trying to find some of the early landmark datasets of fMRI papers to put into OpenfMRI (openfMRI.org), but most of them either say, we can’t find the data anymore, or it’s on a tape but we don’t have the drive that can read it anymore. I have data from 10 years ago on various tape formats that I couldn’t get to if I wanted to, though it seems that the technology has stabilised a bit. The other worry is that you put it on a DVD or a hard drive, but those things decay; people often have the assumption that once you put the data onto physical media it will be there as long as you want it, and that is definitely not the case. I think the best strategy is to replicate data geographically across as many different systems as possible so that there’s no single point of failure. Continue reading →
