Assembled Cognoscenti A friend was asking about what to do with his old digital photo's; anyway that was where it began. When I started looking at the durability, of data across various storage options; HDD's,SSD's, DVD's I was shocked to realise; that  a hard copy of a photograph (laser or inkjet) actually had a much longer expected life; than any of them (assuming;cool, dry, dark environment) . DVD's burnt on a desktop machine =< 10years and HDD's,SSD's often =< 3years. Thus arose my interest in personal digital archiving, with reference particularly to 'digital tombstones'; the reference to tombstones being because these obviously preserve information for >= 1000 years. Currently the most durable digital medium seems to be  the M-disk technology ( >=200 years); but digital archiving seems to involve more than just hardware, there are the 'triage' questions of what to keep and protocol questions of how to structure it, so that it has a common access format....etc When I started looking up personal archiving standards I found http://www.digitalpreservation.gov/documents/ebookpdf_march18.pdf; but couldn't find much in Australia specifically, beyond a discussion paper: https://www.caara.org.au/wp-content/uploads/2010/03/DigitalArchiving21C.pdf Anyone else interested in this area ? regards Rohan Mcleod
