# Records Knowledge and Memory Across Generations
**Domain:** Deep Time / Knowledge Preservation / Nuclear Governance
**Doc Type:** Canonical Wiki Entry
**Maturity:** Developed
**Evidence / Concept Status:** Established OECD NEA international initiative
## Definition
**Records, Knowledge and Memory Across Generations (RK&M)** is the OECD Nuclear Energy Agency initiative for preserving understandable information about radioactive-waste repositories across generations.
## Why It Matters for Deep Time Continuity
Continuity requires not only preserving state but preserving the meaning, provenance, instructions, and institutions needed to interpret it.
## Existing Architecture / Evidence
The NEA has developed a preservation toolbox, essential-record concepts, and key information files to keep repository knowledge socially recoverable across long horizons.
## Evidentiary Boundary
Nuclear repositories are the source domain; continuity use is structural analogy.
