Completed Phase 2 of the schema-of-schemas implementation with full
markdown schema support. This enables schemas to be authored as
markdown files with rich documentation and embedded JSON schemas.
Core Implementation (markitect/schema_loader.py):
- MarkdownSchemaLoader class with comprehensive parsing capabilities
- YAML frontmatter extraction with error handling
- JSON code block extraction with section preference (## Schema Definition)
- Metadata merging with x-markitect-source tracking
- Schema saving with template support and round-trip capability
- Helper methods: list_json_blocks(), validate_schema_structure()
Test Coverage (tests/test_schema_loader.py):
- 35 comprehensive unit tests (100% passing)
- Tests for loading, parsing, saving, round-trip conversion
- Edge case handling (empty files, binary files, malformed blocks)
- Fixed binary file test to use invalid UTF-8 sequences
Example Schema (markitect/schemas/manpage-schema-v1.0.md):
- First markdown schema following naming convention
- Complete manpage schema with frontmatter + documentation + JSON
- Demonstrates section classification and content control
- Shows proper structure for future schema authors
Documentation (roadmap/schema-of-schemas/SCHEMA_LOADER_GUIDE.md):
- Comprehensive user guide (600+ lines)
- API reference with examples
- Best practices and troubleshooting
- Integration patterns for CLI and validator
Progress Tracking:
- Updated TODO.md with Phase 2 completion
- Updated CHANGELOG.md with implementation details
- Next: Phase 3 - Schema-for-Schemas Metaschema
