Logical preservation

Definition
Logical preservation is

"the ability to reconstruct streams of bits in a meaningful way that computers and humans can interpret, use, repurpose, and understand at any arbitrary point in the future. Logical preservation is a difficult problem because people and organizations are using increasingly complex software tools, data models, semantics, and concepts to capture, represent, [display]], and analyze many different types of information. Formats, standards, software, and semantics evolve at different rates for different types of digital information, adding to the complexity of designing and selecting effective long-term preservation strategies. |undefined"
