RDF Export Override Update Report

Context

  • Agent: gpt-5-codex

  • Date (UTC): 2025-10-23 16:42:23

  • Task: Recognize bare IRIs on arrow labels with the same reliability afforded to individual nodes while honouring repository contributor workflow requirements.

Summary of Work

  1. Executed required setup steps inside src/main/webapp/plugins/rdfexport/:

    • bun install

    • bun run setup:uv

    • bun run setup:pyodide

  2. Validated the reported failure via python -m debug --scenario flowchart-tweaked to capture the arrow CURIE expansion error (NotInKnownException).

  3. Reviewed meta builder architecture using meta_builder/readme.md to respect override regeneration expectations.

  4. Implemented targeted updates in legacy/overrides/curie_validator.py:

    • Added _looks_like_absolute_uri helper to detect bare IRIs.

    • Normalised arrow identifiers by converting absolute IRIs to known CURIEs when a namespace match exists.

    • Allowed absolute identifiers to bypass _ensure_known_curie while still participating in downstream processing.

    • Ensured property tracking (object/datatype) uses the normalised identifier.

    • Enhanced serialise_to_graph with _resolve_property_uri so absolute properties are emitted as URIRef values when no CURIE mapping is available.

  5. Regenerated generated assets using python -m meta_builder --output legacy/draw_io_parser.py and python -m meta_builder --output drawio_meta.py to apply the overrides.

  6. Ran python -m debug --scenario flowchart-tweaked to confirm the scenario now succeeds and produces isomorphic pipeline/plugin graphs.

  7. Executed the mandated test workflow:

    • bun run fix

    • bun run check

    • bun run test:log:linux

    • bun run debug:all:log:linux

    • bun run test:pytest:all:log:linux

    • bun run test:bun:all:log:linux

    • bun run test:all:log:linux

  8. Verified graph behaviour programmatically to ensure literal targets for bare-IRI properties remain intact.

  9. Documented results (this report) and prepared for changelog + PR messaging.

Testing Evidence

  • python -m debug --scenario flowchart-tweaked → passes with consistent turtle output.

  • bun run check → lint and formatting checks succeeded after automatic fixes.

  • bun run test:log:linux → Bun integration tests pass (30 pass / 11 skip / 0 fail).

  • bun run test:all:log:linux → Aggregate Bun + pytest workflow succeeds (no failures).

Additional Notes

  • Added defensive logic only within overrides; generated parser and metadata files updated via meta builder CLI.

  • No modifications were required for TypeScript sources.

  • ChangeLog update pending alongside final commit/PR preparation.
