worph 0.1.6

Materialize RDF knowledge graphs from RML/YARRRML mappings with Morph-KGC compatibility

worph

worph is a public project at wordlift/worph, forked from morph-kgc. It keeps compatibility with retained morph_kgc imports while evolving the primary implementation under src/worph/.

Overview

worph provides RML/YARRRML materialization flows with compatibility for existing morph_kgc consumers. The codebase includes regression suites and compatibility shims used in CI to validate behavior against retained tests.

Repository Layout

• src/worph/: primary package implementation
• .ci_shims/morph_kgc/: compatibility shim re-exporting from worph
• test/: regression and issue-driven test suites
• examples/: runnable configs and sample scripts
• specs/: compatibility, playbook, and agent-guidance documents
• specs/agents/: specialist subagent briefs used during planning/review
• docs/: operational documentation

Quick Start

uv sync --extra test
uv run python -m worph examples/csv/config.ini

CLI Commands

Run using the package entrypoint:

uv run worph examples/json/config.ini

Equivalent module form:

uv run python -m worph examples/xml/config.ini

Testing

Run full CI-aligned tests with shim compatibility enabled:

PYTHONPATH=.ci_shims:src uv run pytest -q

Run the explicit shim validation test:

PYTHONPATH=.ci_shims:src uv run pytest -q test/test_ci_shim_uses_worph.py

Compatibility

Some retained tests still import morph_kgc. CI sets PYTHONPATH=.ci_shims:src so imports resolve to .ci_shims/morph_kgc first, then delegate to worph.

Release

Publishing to PyPI is handled inside .github/workflows/ci.yml.

Trusted Publisher settings on pypi.org:

• Owner: wordlift
• Repository: worph
• Workflow name: ci.yml
• Environment: empty (unless you add one in GitHub)
