**Project:** Markdown-First Schema System
**Status:** Planning → Implementation
**Timeline:** 8-10 days

## What We're Building

### Goals
1. ✅ Filename convention: `{domain}-schema-v{version}.md`
2. ✅ Markdown-first schema format (documentation + embedded JSON)
3. ✅ Schema-for-schemas to validate all schemas
4. ✅ Migrate existing schemas to new format
5. ✅ Clean up duplicate/legacy schemas

### Why
- **Consistency:** Enforced naming and versioning
- **Alignment:** Markdown-first matches MarkiTect philosophy
- **Documentation:** Rich docs alongside schemas
- **Validation:** Schema-for-schemas ensures quality
- **Maintainability:** Clear versions and structure

## Implementation Phases

1. **Phase 0:** Planning & Setup (0.5 days) ← **Current**
2. **Phase 1:** Filename Convention (1 day)
3. **Phase 2:** Markdown Loader (2-3 days)
4. **Phase 3:** Schema-for-Schemas (2 days)
5. **Phase 4:** Schema Migration (1-2 days)
6. **Phase 5:** CLI & Docs (1 day)
7. **Phase 6:** Testing (1 day)

## Current Status

### Completed
- [x] Directory structure created
- [x] Planning documents moved to roadmap
- [x] Comprehensive workplan written
- [x] Example markdown schema created

### Next Steps
1. Complete Phase 0 planning artifacts
2. Begin Phase 1 implementation
3. Checkpoint review after Phase 1

## Key Decisions

### Naming Convention
**Format:** `{domain}-schema-v{major}.{minor}.md`
**Example:** `manpage-schema-v1.0.md`

### Schema Format
**Markdown with embedded JSON:**
```markdown
---
schema-id: "https://markitect.dev/schemas/manpage/v1"
version: "1.0.0"
---

# Manpage Schema v1.0

[Documentation...]

## Schema Definition

```json
{ ... JSON schema ... }
```
```

### Schema Migration Plan
```
Old → New
──────────────────────────────────────────────────
terminology-schema.json      → terminology-schema-v1.0.md
api-documentation            → api-documentation-schema-v1.0.md
enhanced-manpage             → manpage-schema-v2.0.md
markdown-manpage             → REMOVE (duplicate)
markdown-manpage-schema.json → REMOVE (duplicate)
```
