# Introduction

This Quarto document provides a comprehensive guide to the PT-CHN schema. It can be rendered to HTML, PDF, or other formats while maintaining consistent formatting and structure. The document is designed to serve both as a reference guide and as training material for new users.
The Plain-Text Chronological Hierarchical Notation (PT-CHN) is a robust naming convention designed for managing Large Language Model (LLM) conversations. This schema optimizes for searchability, readability, and maintainability while using only ASCII characters.

## Core Format

The base format follows this structure:

@YYMMDD-[CAT]-{TAG1.TAG2}-#ID-<V00>-!P-*S: Title
Schema Components
Temporal Marker (@YYMMDD)
Format: @YYMMDD
Example: @241107
Purpose: Chronological organization and temporal search
Rules:
YY: Two-digit year
MM: Two-digit month
DD: Two-digit day
Category Code ([CAT])
Primary classification codes:
Code	Description	Use Case
DEV	Development	Technical development tasks
RES	Research	Investigation and research
PRJ	Project	Project management
EXP	Experiment	Testing and experimentation
STD	Study	Learning and analysis
ANA	Analysis	Detailed examination
Tag System ({TAG1.TAG2})
Tags use dot notation for hierarchical organization:
{DOMAIN.SUBDOMAIN}

Common tag combinations:
Tag Combination	Description
PROMPT.FUNC	Functional prompting
AI.ARCH	AI architecture
SYS.OPT	System optimization
Identifier (#ID)
Format: #XNN where:
X: Alpha character (A-Z)
NN: Two-digit number (01-99)
Examples:
#A01 - First series, first item
#B01 - Second series, first item
#Z99 - Final series, last item

Version Control (<V00>)
Version notation follows semantic principles:
Notation	Meaning	Usage
<V01>	Initial	First version
<V02>	Revision	Subsequent updates
<VXX>	Experimental	Testing versions
Priority Indicator (!P)
Priority levels and their meanings:
Code	Priority	Description
!C	Critical	Immediate attention required
!H	High	Important, time-sensitive
!M	Medium	Standard priority
!L	Low	Can be deferred
!X	None	No priority assigned
Status Marker (*S)
Current state of the conversation:
Code	Status	Description
*IP	In Progress	Active development
*DN	Done	Completed
*RV	Review	Needs review
*BL	Blocked	Cannot proceed
*AR	Archived	Completed and stored
*HL	Hold	Temporarily paused
*XX	Unknown	Status unclear
Implementation Guidelines
Search Patterns
Basic Searches
@24     - All entries from 2024
[DEV]   - All development entries
{PROMPT - All prompt-related entries
#A01    - Specific identifier
<V02>   - All version 2 items
!H      - All high priority items
*IP     - All in-progress items

Combined Searches
@24.*IP     - In-progress items from 2024
[DEV].*RV   - Development items needing review
!H.*IP      - High-priority in-progress items

Best Practices
Version Control Management
Version Incrementing Rules:
Increment for substantial changes
Use VXX for experiments
Document changes in description
Priority Management
Priority Assignment:
Default to !X when unclear
Review priorities weekly
Reserve !C for genuine emergencies
Status Tracking
Status Update Rules:
Update with each interaction
Document status changes
Regular status audits
