Completed Phase 3 of the schema-of-schemas implementation with a
comprehensive metaschema that validates all MarkiTect schema files
against conventions and standards.

Metaschema Implementation (schema-schema-v1.0.md - 650+ lines):
- Validates core JSON Schema fields ($schema, $id, title, description)
- Validates MarkiTect version field (SemVer: major.minor.patch)
- Validates $id URL format (HTTPS with version path)
- Validates MarkiTect extensions:
  - x-markitect-sections: section classifications and content rules
  - x-markitect-content-control: pattern and quality validation
  - x-markitect-metadata: status, authors, tags
  - x-markitect-source: loader metadata (auto-added)
- Section classification validation (required, recommended, optional,
  discouraged, improper)
- Content control pattern validation
- Comprehensive documentation with examples and usage guides

CLI Command (markitect schema-validate):
- Validates schema files against metaschema
- Supports both markdown and JSON schema files
- Detailed error reporting with schema paths
- Structure validation recommendations
- Exit codes for CI/CD integration

Test Coverage (tests/test_schema_metaschema.py - 12 tests, 100% passing):
- Metaschema self-validation
- Manpage schema validation
- Required fields enforcement
- Version format validation (valid and invalid cases)
- $id format validation (valid and invalid cases)
- Section classification validation
- Complete schema with all extensions

Validation Results:
- ✅ Metaschema validates itself successfully
- ✅ Manpage schema (v1.0.md) validates successfully
- ⚠️  Terminology schema needs migration (missing version, incorrect $id)

Progress Tracking:
- Updated TODO.md with Phase 3 completion
- Updated CHANGELOG.md with implementation details
- Next: Phase 4 - Schema Migration

# Schema-for-Schemas v1.0
## Overview
This metaschema validates that MarkiTect schema files follow conventions and standards. It ensures schemas are well-formed, properly versioned, and include required MarkiTect extensions.
**Purpose**: Quality assurance for schema authors
**Validates**:
- Core JSON Schema fields (title, description, $schema, $id)
- Version format (SemVer: major.minor.patch)
- $id URL format (HTTPS with version)
- MarkiTect extensions (x-markitect-*)
- Section classification structures
- Content control patterns
## Schema Conventions
### Required Fields
Every MarkiTect schema MUST include:
1. **$schema**: JSON Schema version (draft-07)
2. **$id**: Canonical HTTPS URL with version
3. **title**: Human-readable schema name
4. **description**: Brief explanation of what the schema validates
5. **version**: SemVer version string (major.minor.patch)
### Recommended Fields
Schemas SHOULD include:
- **type**: Root schema type (usually "object")
- **properties**: Object properties definition
- **required**: Array of required property names
### MarkiTect Extensions
#### x-markitect-sections
Defines document sections with classifications and content rules.
**Structure**:
```json
{
"SECTION_NAME": {
"classification": "required|recommended|optional|discouraged|improper",
"heading_level": 2,
"content_instruction": "What this section should contain",
"min_paragraphs": 1,
"max_paragraphs": 10,
"min_code_blocks": 0,
"max_code_blocks": 5,
"alternatives": ["ALTERNATIVE_NAME"],
"error_message": "Error if validation fails",
"warning_if_missing": "Warning if section absent"
}
}
```
**Classifications**:
- `required`: Section must be present
- `recommended`: Section should be present (warning if missing)
- `optional`: Section may be present
- `discouraged`: Section should be avoided (warning if present)
- `improper`: Section must not be present (error if present)
#### x-markitect-content-control
Defines content patterns and quality metrics.
**Structure**:
```json
{
"section_name": {
"required_patterns": ["regex1", "regex2"],
"discouraged_patterns": ["regex3"],
"forbidden_patterns": ["regex4"],
"content_quality": {
"min_words": 50,
"max_words": 1000,
"readability_target": "technical|general",
"min_sentences": 3
},
"content_instructions": ["instruction1", "instruction2"],
"link_validation": {
"check_internal": true,
"check_external": false,
"allow_fragments": true
}
}
}
```
#### x-markitect-metadata
Additional schema metadata.
**Structure**:
```json
{
"status": "stable|draft|deprecated",
"authors": ["Author Name <email@example.com>"],
"created": "2026-01-04",
"updated": "2026-01-04",
"tags": ["tag1", "tag2"]
}
```
#### x-markitect-source
Automatically added by schema loader (not in schema file).
**Structure**:
```json
{
"file": "/path/to/schema-v1.0.md",
"filename": "schema-v1.0.md",
"format": "markdown",
"frontmatter": {...}
}
```
## Validation Rules
### $id Format
Must be HTTPS URL with version:
```
https://markitect.dev/schemas/{domain}/v{major}
```
**Examples**:
- ✅ `https://markitect.dev/schemas/manpage/v1.0`
- ✅ `https://markitect.dev/schemas/api-documentation/v2.0`
- ❌ `http://example.com/schema` (not HTTPS)
- ❌ `https://markitect.dev/schemas/manpage` (no version)
### Version Format
Must be SemVer (major.minor.patch):
```
{major}.{minor}.{patch}
```
**Examples**:
- ✅ `1.0.0`
- ✅ `2.5.3`
- ❌ `1.0` (missing patch)
- ❌ `v1.0.0` (has 'v' prefix)
### Title Format
Should be descriptive and end with "Schema":
**Examples**:
- ✅ "Unix Manual Page Schema"
- ✅ "API Documentation Schema"
- ❌ "Schema" (too generic)
## Usage
### Validating a Schema
```bash
# Validate a schema file
markitect schema-validate manpage-schema-v1.0.md
# Show detailed errors
markitect schema-validate manpage-schema-v1.0.md --detailed-errors
```
### Programmatic Usage
```python
from pathlib import Path
from markitect.schema_loader import MarkdownSchemaLoader
# Load schema to validate
loader = MarkdownSchemaLoader()
schema_data = loader.load_schema(Path("my-schema-v1.0.md"))
# Check structure
issues = loader.validate_schema_structure(schema_data['schema'])
if issues:
for issue in issues:
print(f"⚠️ {issue}")
```
## Common Validation Errors
### Missing Required Fields
**Error**: `Missing required field: $schema`
**Solution**: Add `$schema` field:
```json
{
"$schema": "http://json-schema.org/draft-07/schema#",
...
}
```
### Invalid $id Format
**Error**: `$id should be a full HTTPS URL`
**Solution**: Use proper format:
```json
{
"$id": "https://markitect.dev/schemas/my-domain/v1.0",
...
}
```
### Invalid Version Format
**Error**: `version must be in SemVer format (major.minor.patch)`
**Solution**: Use three-part version:
```json
{
"version": "1.0.0",
...
}
```
### Invalid Section Classification
**Error**: `Invalid classification value: 'mandatory'`
**Solution**: Use valid classification:
```json
{
"x-markitect-sections": {
"SYNOPSIS": {
"classification": "required",
...
}
}
}
```
Valid values: `required`, `recommended`, `optional`, `discouraged`, `improper`
