Long-Term Digital Preservation

# Long-Term Digital Preservation **Entity class:** Concept or analytic term **Domain:** Digital Preservation / Continuity Infrastructure **Doc Type:** Canonical Preservation Hub **Maturity:** Established Practice / Prospective Application ## Relationships - **Collection route:** [[collections/Consciousness Continuity|Consciousness Continuity]] places long-term preservation within the broader continuity problem. - **Adjacent biological-preservation concept:** [[wiki/Brain Preservation|Brain Preservation]] concerns retaining potentially identity-relevant brain state; a preserved digital archive alone does not establish survival or revival. - **Source article:** [[articles/Information Persistence in Complex Systems|Information Persistence in Complex Systems]] examines persistence across changes in substrate and custody. ## Definition **Long-term digital preservation is the continuing work required to keep digital information authentic, understandable and usable across changes in media, formats, software, institutions and threat environments.** It is an active process, not passive storage. ## Preservation Functions Functions include fixity checking, redundant storage, documented custody, format and media migration, preservation metadata, audit trails, risk monitoring, recovery testing and retention of the knowledge needed to interpret the object. Significant properties must be identified because a technically readable object can lose the behavior or context that made it meaningful. ## Continuity Boundary These methods are necessary for continuity-bearing state but not sufficient for a person. An archive may preserve records and executable artifacts while no subject is running. [[wiki/Executable Preservation|Executable Preservation]] adds interpreters and environments. [[wiki/Continuity Service Tiers|Continuity Service Tiers]] separates cold preservation, warm readiness and hot execution. [[wiki/Continuity Disposition|Continuity Disposition]] supplies the authority boundary. Permission to preserve an archive does not imply permission to assemble a person-model, and permission to reconstruct does not imply permission to activate. Preservation metadata should record the applicable election and its version without exposing private directive content more broadly than necessary. Preservation actions can also alter identity-bearing state. Every migration and repair should enter the [[wiki/Digital Thread|Digital Thread]] and remain available for audit. ## Simple Reminders, Quotations, and Thoughts  > "The aim is to preserve the functions of the mind, not the biological tissue." > **— Randal A.

But no such technology is in sight despite the steady advances of Moore's Law doubling of transistor density on computer chips every two years or so. Nor have we cracked the code of the random pulse train from a single neuron. Hence we are not even close to making sense of the interlocking pulse trains of the billions of chattering neurons in a functioning human brain.” > **— Bart Kosko**, *2009, Edge Annual Question, “WHAT WILL CHANGE EVERYTHING?”* [[reminders/Preservation/Future Biocomputing May Back Up the Neural Information That Defines Us by Bart Kosko|Future Biocomputing May Back Up the Neural Information That Defines Us by Bart Kosko]] > “How do we create and maintain backup options for humanity to quickly rebuild an advanced civilization after a catastrophic human extinction event?” > **— Albert Wenger**, *2018, Edge Annual Question, “WHAT IS THE LAST QUESTION?”* [[reminders/Preservation/How Do We Back Up Civilization Against Human Extinction by Albert Wenger|How Do We Back Up Civilization Against Human Extinction by Albert Wenger]] > “Now, all this may be coming to an end, for one of the things we humans, with our evolved intelligence, are working hard at is trying to eradicate death. This is an understandable enterprise, for nobody wants to die—genes for wanting to die rarely last long in a species. For millennia, human thinkers have dreamed of conquering old age and death: the fight against it permeates our art and culture, and much of our science. We personify death as a spectre and loathe it, fear it and associate it with all that is bad in the world. If we could conquer it, how much better life would become.” > **— Kate Jeffery**, *2013, Edge Annual Question, “WHAT *SHOULD* WE BE WORRIED ABOUT?”* [[reminders/Digital Afterlife/Human Intelligence Is Trying to Eradicate Death by Kate Jeffery|Human Intelligence Is Trying to Eradicate Death by Kate Jeffery]] > “Now we are reaching the point where we have the ability to archive every message, every telephone conversation, every communication between human beings anywhere on the planet. For the first time, we as a species have the ability to remember everything that ever happens to us.” > **— Charles Seife**, *2009, Edge Annual Question: “WHAT WILL CHANGE EVERYTHING?”* [[reminders/Memory/We Can Now Remember Everything That Ever Happens to Us by Charles Seife|We Can Now Remember Everything That Ever Happens to Us by Charles Seife]] > “In 1992, the artist Thomas Bayrle wrote that the great mistakes of the future would be that as everything became digital, we would confusememory with storage.” > **— Kevin Slavin, reporting Thomas Bayrle**, *2009, Edge Annual Question: “WHAT WILL CHANGE EVERYTHING?”* [[reminders/Memory/The Great Mistake Will Be Confusing Memory With Storage by Kevin Slavin|The Great Mistake Will Be Confusing Memory With Storage by Kevin Slavin]] > “Will reading and writing survive given the seduction of video and audio?” > **— Marti Hearst**, *2018 Edge Annual Question, question* [[reminders/Preservation/Will Reading and Writing Survive Video and Audio by Marti Hearst|Will Reading and Writing Survive Video and Audio by Marti Hearst]] > “What libraries will we have to build when cloning becomes infinitely expandable?” > **— Thomas A.
