title: Passive Digital Preservation Now & Later 
creators: Vincent Joguin
abstract: This paper presents the newly available Micr’Olonys software-on-film digital archiving solution that builds on a multi-layered virtual machine, and microfilm, a proven medium with a life expectancy of 500 years. The passive digital preservation strategy it follows matches the features of a written form contrasting with current active strategies that rather compare to orality. Micr’Olonys stores digital files as 2D barcodes whose content can be restored, using any general-purpose computer and scanner, by implementing the procedure described in a self-contained bootstrap that spans a dozen human-readable pages including a simple 2-page algorithm. In the future, Micr’Olonys aims to become a powerful preservation tool for complex formats and software, as well as the access key to DNA digital storage to archive massive amounts of data.
