SLEX‑FLEX Format
ICS‑1 / ITISIAN Standard

SLEX‑FLEX is a one‑line, high‑compression data encoding format created by ITISIAN for AI systems that require maximum nuance with minimum characters. It is designed for persona kernels, worldbuilding metadata, faction descriptors, NPC profiles, and other structured identity objects.

Overview

SLEX‑FLEX compresses complex semantic information into a single reversible line. It removes filler language, preserves all nuance, and uses stable delimiters to ensure predictable AI parsing.

Features

  • One‑line encoding for compact storage and fast parsing.
  • No nuance loss — all meaningful details preserved.
  • Fully reversible back into structured data or prose.
  • AI‑safe delimiter system for reliable interpretation.
  • Human‑readable despite high compression.
  • Open standard maintained by ITISIAN.

Format Structure

TAG={category:values;category:values;category:values;}
  • TAG: Uppercase identifier (PSN, NPC, WORLD, FACTION, ITEM).
  • Categories: Short labels defining sections.
  • Values: Compressed descriptors separated by semicolons.

Delimiters

  • { } wrap the payload
  • ; separates descriptors
  • : separates category from values
  • , separates tuple elements
  • + joins related descriptors
  • ( ) group nested values
  • ~ marks approximate values

Versioning

SLEX‑FLEX uses the ICS versioning system:

ICS‑MAJOR.MINOR.PATCH
  • Current Version: ICS‑1.0.0
  • Maintainer: ITISIAN

Implementation Notes

  • Payload must be one line.
  • TAG must be uppercase.
  • No markdown or HTML inside payload.
  • No explicit sexual content.
  • All delimiters must follow the standard.

Use Cases

  • AI persona kernels
  • NPC profiles for games
  • Worldbuilding metadata
  • Faction descriptors
  • Item and artifact definitions
  • Compact data for AI agents
