# Summary

Condensed information

Layer: Infrastructure · Category: Data Structures

## Mechanism

A compressed representation of a [Datum](https://mindscape.world/scapes/bootstrap/Datum.md) or [Artifact](https://mindscape.world/scapes/bootstrap/Artifact.md) that retains high-[Value](https://mindscape.world/scapes/bootstrap/Value.md) (salient) information while discarding redundancy.
